Warning

Caution

SAFETY PRECAUTIONS

Design Precautions

Install a safety circuit external to the PLC that keeps the entire systemsafe even when there are problems with the external power supply orthe PLC module. Otherwise, serious trouble could result fromerroneous output or erroneous operation.

- Outside the PLC, construct mechanical damage preventing interlockcircuits such as emergency stop, protective circuits, positioning upper and lower limits switches and interlocking forward/reverse operation. When the PLC detects the following problems, it will stop calculation andturn off all output in the case of watchdog timer error, module interfaceerror, or other hardware errors. However, one or more outputs could be turned on when there areproblems that the PLC CPU cannot detect, such as malfunction of output device (relay, transistor, etc.) itself or I/O controller. Build a fail safecircuit exterior to the PLC that will make sure the equipment operatessafely at such times. Also, build an external monitoring circuit that willmonitor any single outputs that could cause serious trouble.

Make sure all external load connected to output does NOT exceed the rating of output module. Overcurrent exceeding the rating of output module could cause fire, damageor erroneous operation.

Build a circuit that turns on the external power supply when the PLCmain module power is turned on. If the external power supply is turned on first, it could result in erroneousoutput or erroneous operation.

3.1 Redundant CPU System Redundant CPU system can be realized through connecting two CPU systems to redundant base as shown in the following figure. That is to say, if an error of master occurred during operation, GMR-B automatically becomes master and continues operation. After a failure of GMR-A recovered, user can switch the master to GMR-A using program tool and key switch.

[Fig. 3.1] Slot of Redundant Basic Base

* Enables Distributed Control System to be configured with Communication Module mounted at I/F Module mounting place. * In Redundant Base, Redundant CPU is located at left and right with the center of DIF Module. (Both of CPU O/S versions should be the same.) It should have the same kinds of module at position 0, 1, 2 and 3 of GMR-A and position 0, 1, 2 and 3 of GMR-B as shown in [Fig. 3.1]. In other words , If G3L-EUEA(Enet) module mounted at slot 0 of GMR-A, G3L-EUEA(Enet) module should be also mounted at slot 0 of GMR-B.

3.2 Redundant Input/Output System Input/Output depends on user’s selection and can be used as Redundant I/O, Switched I/O, One-sided I/O, and its combination according to parameter setting.

3.2.1 Switched Input/Output CPU-A and CPU-B operates simultaneously with the same program and data synchronized when data synchronization required. If master stopped operation due to a failure of CPU, stand-by CPU takes over the operation immediately and this time switched input/output enables continuous operation without change of state.

In this structure, it called CPU redundant because no redundant Input/Output established. Set each base to ‘Switched Input/Output’ at parameter setting. Stand-by CPU checks switched base for connection periodically.

3.2.2 Redundant Input/Output(I/O Redundant) CPU-A and CPU-B operates simultaneously with the same program and data synchronized when data synchronization required. If master stopped operation due to a failure of CPU, stand-by CPU takes over the operation immediately and this time I/O connected to master turns OFF among Redundant I/O setting bases.

In this structure, both of master and stand-by CPU control I/O module and use the same value more than 2 among 3 as input data, compared with Redundant I/O A, Redundant I/O B and Switched I/O.

In GMWIN, set each base to ‘Redundant I/O’ and both base number setting switch to the same value. Also set the position of Switched I/O for input comparison and output feedback.

3.2.3 One-sided Input/Output CPU-A and CPU-B operates simultaneously with the same program and data synchronized when data synchronization required. If CPU-A stopped operation due to a failure of CPU, attached I/O stops the operation and the output connected to it turns OFF. Set each base to ‘One-sided I/O’ and this structure is used when no backup required, saving costs of entire redundancy.

Remarks

• One-sided I/O shall be installed only at CPU-A. • One-sided I/O can be installed with only Digital Contact I/O Module.

The following shows the example of Redundant I/O, Switched I/O, One-sided I/O, and combined structure. ‘Switched I/O #1’ is used for switched I/O and ‘switched I/O #2’ for Redundant I/O.

5.2.7 Power Redundant Module Specifications

1) Usage • Used to prevent a failure using two power modules in a base. • Used in Redundant Basic Base and Switched I/O Base.

2) Type • There are 4 types of GMR-PA1A, GMR-PA2A, GMR-PA1B, GMR-PA2B as operating Input Power Voltage and Output Power/Voltage. • For detailed, refer to ‘5.3 Power Module’.

3) How to replace power module (1) Check the power module for error on Switched Base:

If an error occurred in any of redundant power modules, system operates normally and raises warning message.

If power error occurred in Switched Base, ‘_E_RPWR_WR’(Redundant Power Error of Extended Base)flag turns ON among System Warning Flags. Users replace the power module with LED off among Switched Base connected to the channel of which Error LED illuminated in Interface Driver Module(FDIA).

(2) Replace Power Module: Any power module due to an error or old should be replaced immediately. Remove the power module during normal operation and mount new module. This time you should use redundant power module.

(7) When communication or interface module error occurred in Basic Interface (When a failure occurred in network line not communication module, master changeover is disabled.)

2) During redundant operation, master auto changeover is disabled in the following conditions. This time, warning message will be displayed.

(1) When an error occurred in any redundant power of switched base (2) If stand-by error occurred in a failure of master

A) Operation stops if the same error detected. B) In case of the above A), if mask flag set on the desired error, continues operation without master changeover. C) If master and stand-by not having the same failure e.g. cause of failure not redundant, continues operation without master changeover (Ex. If a failure detected at another position among triplex input).

3) When normal redundant operation disabled due to a failure of DIF module, master is changed into stand-alone operation and stand-by stops operation.

Chapter 7. Basic Concept of Program

7-1


7.1 Program Running Structure • Program is written by GMWIN, and then compiled and run by transmitting to PCL after converting active file compiling the program and converted to active file. • Program consists of Scan and Task Program. Scan Program is operated repetitively per scan and Task Program is operated by task.

• Scan Program is operated and then stopped from the start to the end in accordance with registered order in project. This total process is called “1 scan”. • After operating the Program from the start to the end as mentioned above, running the Program repetitively with the same process is “Repetitive operation system”. • Reading and storing the status of input module in the input image area before computing Scan Program and detecting the contents of the output image area after computing Scan Program is called I/O Refresh. • GLOFA PLC series is Repetitive operation system and do not input and output directly the status of I/O during operation, and just operated by running I/O refresh. In this case, the status of each I/O contact is stored at the memory area in PLC. This area is called I/O image area.

7.2 Program Operation

7.2.1 Program Types Each Program of GLOFA PLC is generated using operator, function and function block that consist of Programs and divided into the followings per operating condition of Program. 1) Initial Program

• Initial Program for cold or warm restart: operated by _INIT Task • Initial Program for hot restart: operated by _H_INIT Task

2) Task Program • Positive period Task Program: Max. 32 EA • Outside Contact Task Program: Max. 16 EA • Inside Contact Task Program: Max. 16 EA

3) Scan Program • Max. 180 EA: 180 minus the Number of assigned Task Program are available.

4) Error Program • Error Task Program : Operated by _ERR_SYS Task

7.2.2 How to Run Program 1) Initialization Program

Refer to “7.3 Restart Mode” regarding each restart mode. • It is used to initiate system such as special module as initial program (_INIT Task) when operating cold or worm restart mode. Initial program performs repetitive operation until satisfying setting condition (until INITDONE flag is on at initial program). In this case, operate I/O Refresh. • When operating on Hot Restart mode, the purpose of Initial Program is to start from stopped step when power failure occurred. Initial Program is used to need special module to restore to condition before power failure or outside condition to make for normal operation. This initial program performs repetitive operation until setting condition satisfied with (until INITDONE flag is on at initial program); do not operate Output Refresh during operating Hot Restart Initial Program Use ‘DIREC_O’ function as output refresh is needed at Hot Restart Initial Program. After completing Hot Restart Initial Program, run Scan Program from previous stopped step and complete Scan Program that was stopped. In this case, do not operate Output Refresh and operate normal I/O Refresh from the next Scan. • During initial program, system operating status flag_INIT_RUN turns ON.

2) Task Program

• Program assigned by Positive period Task operates program at time interval set in task. • Program assigned by Outside interrupt task operates program by Outside interrupt contact signal occurred from interrupt module. • Program assigned by inside contact task operates program when rising edge of inside contact occurred.


7-3

3) Scan Program

Program that is not assigned as Initial Program and Task Program among programs written by user becomes Scan Program automatically. Scan Program is running repetitively regardless of task and the priority is the lowest. And Scan Program is running sequential repetitive operation in accordance with registered order on GMWIN screen.

4) Error Program

It is error task program used when system error occurred during operating a user program. User operates program under _ERR_SYS task condition after writing a program against system error. It is possible to protect stopping of system operating with controlling System Error Mask Flag at Error Task Program (see “9.4 Error Remedy”).

7.2.3 Program Flow Chart Scan Program operates sequentially from start to end per written orders. This kind of Scan Program operates as repetitive operation system and the process is “1 scan”. Temporarily stop the Program that is currently operating and operate related Task Program when the active condition of Positive period Task or Outside Contact Task Program occurred during program operating. After operating program, check the active condition of inside contact task program and operate Task Program occurred active condition.

7.2.4 Synchronization method during redundant operation

7.2.4.1 Synchronization

Synchronize data and operation point between CPU modules when running like below during redundant operation.

(1) Scan Input (Image Area) (2) Scan Output (Image Area) (3) Immediate Input (Command) (4) Immediate Output (Command) (5) When starting Program Scan (6) When starting Task (7) When processing communication (8) When processing GMWIN communication (9) When running function block for special module (10) When changing time data inside CPU

7.2.4.2 Synchronization Method

The followings are operation details of synchronization during redundant operating. 1) Input Scan (Image Area)

• Switched I/O : Master reads and transmit to standby • Redundant I/O : Operating by value that is equaled two of them when three-input • One-sided I/O : CPU-A reads input data and transfer to CUP-B

2) Scan output (Image Area) • Compare output area data of master and standby before output • Output master value unless the master does coincide. • Restart standby and coincide with master status when un-coincident.

3) Immediate Input (Command) The same method as Scan Input (only, selected input)

4) Immediate output (Command) The same method as Scan output (only, selected input)

5) When starting Program Scan Synchronize Scan start point after Scan END processing and Scan ready

6) When starting Task (1) Make kind of Task, intercepted position and start point matched with. - Scan Task, Positive period Task and Inside Contact Task.

(2) Synchronization Method

• Operate Task of upper priority using program block unit (if several program block is operated by task currently running, process the upper task that is waiting before operating each program block)

• if program block is large, process the task of the upper priority during program block by ‘standby task process function’ of user.


7-5

7) When processing communication

HS communication synchronizes at Scan END and variable communication service is synchronized by function block.

8) When processing GMWIN communication

• Starts communication after assigning CPU to be contacted • Assigned CPU responses singly against communication of GMWIN because status of master and standby of data that is using at operation are equal. If modifying inside data as the communication result of GMWIN and line opened master CPU, data of standby is modified together. (It is possible to monitor detailed operation information of standby after contacting from GMWIN to standby) • Contact is available only through connector of DIF during redundant operating.

9) When running function block for special module Both of switched and redundant I/O performs data synchronization immediately.

10) Synchronization of time data in CPU • Two CPUs change base time together such as increased time change in CPU. • Perform synchronization of time rate after matching with two CPUs to remove errors. The base becomes value of master and time running data is used to monitor master. (Set standby value to value of master – to remove cumulative error by long operation)


7-6

7.3 Restart Mode Restart Mode is to set whether to operate RUN Mode after initialization parameters and system when stating to operate RUN Mode by returning Mode or re-power on. It consists of Cold, Worm and Hot. The followings are operating condition of each re-start Mode (See “12.1 Basic Parameter” for setting method).

7.3.1 Cold restart • It is performed when restart mode is set to Cold Restart at parameter. • Eliminate all data to “o” and set only parameter which initial value is set to initial value. • Though Worm Re-start Mode is set at parameter, operated by Cold Re-start Mode when initial running after program to be run changed. • If pressing manual reset switch more than 5 sec during operating, operated by Cold Restart Mode regardless of setting Re-start Mode

7.3.2 Warm restart • It is performed when restart mode is set to Warm Restart at parameter. • Maintain previous value of data that is set to maintain previous value and the data that is set only initial value is set to initial value. Except this, eliminate all data to “0” • Though Worm Re-start Mode is set at parameter, operated by Cold Re-start Mode when initial running after program changed. • Though Worm Re-start Mode is set at parameter, operated by Cold Re-start Mode if data is abnormal. • If pressing manual reset switch within 5 sec during operating when Worm Re-start Mode is set at parameter, operated by Worm Re-start Mode.

7.3.3 Hot restart • It is a run mode when re-power on after power off during normal operation (in RUN Mode). It is operated on Hot Restart Mode when the time is within Hot Restart allowance setting time until re-power on after power off. • All data and program running factor is restored to the status of before power-off. Program is maintained as sudden power failure because the program runs at the status before power-off. • Operating on Restart Mode set at parameter when excess Hot Restart allowance setting time • If data contents are abnormal, operating on Cold Restart Mode.

Remarks

• Consider the followings when setting Hot Restart allowance time System operates Hot Restart Program when time that is calculated from AC Fail to system checking

completed is within setting time. If power failure occurs again before completing program operation, try again the Hot Restart Program and calculate the time form first power failure.

When a power failure occurred for more than 20ms, it takes proximately 0.5 sec until operating normally after re-power on. Hot Restart allowance time setting is set by sec.

• Above mode is adapted when master CPU operates in shutdown. Standby is not adapted on Restart mode

due to operating under currently operating master condition

• Consider followings when controlling manual reset switch during redundant operating. Total system is operating when controlling reset switch of CPU operated by master switch but only standby

CPU is operating when controlling reset switch of standby CPU.

7.3.5 Restart Mode Application according to Operation Purpose • Cold Restart:

It is used when starting operation after a completion of initialization in whole control system.

• Warm Restart: Several (parts) processes Initialized and then operated but it is used when restarting operation under remembering previous operation result of control system

• Hot Restart:

It is used when starting operation under remembering to several (parts) processes in previous operating status of total control system. Processing status control of parts processed is used to system that is remembered and controlled by inside memory not Outside signal.

GLOFA GM series PLC become stop status after retaining operation data if operation is not available any more due to shut down during operating. And it can operate continuously because previous operation status can be restored. But changing of occurred Outside controller can’t be known under PCL shut down and also requirements that are occurred before stopping are processed following restart.

2) Cold Restart

CPU operates like below when Cold Restart. (1) Delete all previous operation data and initialize parameter. (2) Perform initialization program. In this case run I/O refresh. (3) Start normal scan program.

3) Warm Restart CPU operates like below when Warm Restart.

(1) Complete scan program and task program that are shut down. Do not process FB of special/communication module and operate with previous data. (2) Ignore task and communication service on standby. (3) Perform only input refresh and high-speed link input. (4) Initialize the parameter. (5) Perform initialization program. In this case run I/O refresh. (6) Start normal scan program.

4) Hot Restart CPU operates like below when Hot Restart.

(1) Complete scan program and task program that are shut down. Do not process function block of special/communication module and operate with previous data. (2) Perform the task on standby and ignore communication on standby. (3) Perform only input refresh and high-speed link input. (4) Initialize the parameter.


7-9

(5) Perform Hot initialization program at this time perform only input refresh. If output refresh is necessary, use ‘DIREC_O” function. (6) Start normal scan program.

Remarks

Retain forced ON/OFF data, I/O skip data, failure mask setting data and failure history information when restart. If necessary, delete them with GMWIN.

Task that was shut down or on standby is processed when Warm and Hot restart. Result of performance is output by scan refresh. Therefore process result can be output by input data before power failure.

Positive period task is calculated by adding times which were measured before system shot down (Except time during system shut down at calculating time

Task Num. User assign to not overlap among 0~31

User assign to not overlap among 32~47

User assign to not overlap among 48~63

7.4.2 Processing of Task Program This section provides common processing method and Remarks pertaining to Task Program Process.

7.4.2.1 Characteristics of Task Program

Task Program doesn’t repeat process for every scan like scan program and run when operation condition occurred. Consider this when making task program. For instance if using timer and counter at Positive period Task Program of 10 sec cycle, error of this timer can be max 10 sec. Changed input within 10 sec is not counted because the counter checks the input status of the counter per 10 sec.

7.4.2.2. Performance of Task

Makes new occurred task not interrupt during operating of program block at redundant system. Processes high priority task program among standby task at end point of program block that is running


7-11

• Ends running task and performs standby task during operating task program. • Performs with checking standby task whenever each program block ends during operating scan program

1) Performance delay of standby task during operating scan program

Correct control can not be expected by task program if running time of scan program is longer than running delay allowance time of task required at control system. Use the following method to reduce standby time of task.

• Divide Scan Program in to several program blocks by function. • If program cannot be divided, insert “standby task processing function (SYNC)” by proper interval in program and perform task that is waiting. Total scan time increases due to SYNC function running so Insert necessary minimum quantity

• Total scan time increases as much as task program running time in one scan. Therefore in case of positive period task, setting short cycle more than necessary is not allowed.

2) Standby task running delay during task program running Consider relation between tasks because of running standby task after finishing task on operation during task program running.

• Configure the task program short to reduce other task standby time. Before running standby task, ignore the last occurred task if the same task is required • Determine priority of task per emergency of response by considering in case of various task running simultaneously required.

7.4.2.3 System operation and performance of task when instantaneous power failure

• User definition task doesn’t operate during initialization task program running. • When instantaneous power failure occurred within 20ms, after recovering power failure, perform a task that was waiting before power failure and a task that was occurred during power failure. Task that was occurred redundantly can be ignored. • In case of re-operation by Hot Restart, task that performed before power failure and standby task can be processed but interrupt task that was occurred during power failure or positive period task that was occurred redundantly during power failure will be ignored. • Ignore all tasks, which were occurred during power failure and standby task when re-running with cold or warm restart.

7.4.3 Processing of Positive period Task Program This section provides processing of task program if operation condition of task program is set by positive period 1) Setting item at task

Set running cycle of task that can be operation condition of running task program and priority.

2) Positive period Task Processing Perform positive period task process per setting time interval (performance cycle).

3) Precautions When using positive period task program • When positive period task program is currently running or waiting, if performance requirements of the same task program are occurred, new occurred task is ignored and task crush warning typical flag (_TASK_ERR) is reset. And related location of system error detail flag (TC_BMAP[n]) is marked and issued number of positive period task that performance requirement was ignored at related location of (_TC_CNT[n]) is recorded.


7-12

Remarks

• When setting running cycle of positive period task program, consider that performance requirements of

various positive period task programs can be occurred simultaneously. If using 4 positive period task programs that each cycle is 2, 4, 10 and 20 sec. There can be some

problems such as scan time can extend momentary cause 4 performance requirements are occurred per 20 sec.

7.4.4 Processing of Outside Contact Task Program This section provides process method of task program in assigning the running condition of task program to Outside interrupt contact signal that is input at interrupt module. 1) Setting items at interrupt module

Set the rising and down edge to interrupt module by Dip switch in accordance with required condition of each contact.

2) Setting items at Task

Set contact number and priority of interrupt module to task that is identical the operating condition of running task program

Task number assigned automatically to manage task. Module contact number 0 1 2 3 ... 12 13 14 15

Task number 32 33 34 35 ... 44 45 46 47 3) Outside contact task process

When interrupt at interrupt module occurred by signal authorized from Outside, CPU module recognize this signal and task program that operated by contact occurred signal is performed.

4) Precautions when using Outside contact task program

• When task program that is operated by contact of interrupt module is running or standing by, if performance requirement of task program is occurred by the same contact, new occurred task will be ignored and Outside contact task that is occurred running requirement congestion and occurred number are recorded at task crush warning typical flag (_TASK_ERR) and system error detail flag (TC_BMAP[n]).

• Running requirement of task program can be accepted if operation mode is RUN mode. Running requirement occurred during operating on STOP mode is ignored totally.

7.4.5 Processing of Inside Contact Task Program This section provides process method of task program if setting operation condition of task program to contact of direct parameter (I, Q, M) or auto parameter. 1) Setting items at task

Set contact and priority that can be operation condition of performing task program. Confirm the task number for task management.

2) Inside contact point task process Check the status of the contacts that can be operation condition of inside contact task program and then perform the inside contact task programs occurred rising edge per priority after finishing performance of scan program at CPU module.

3) Precautions when using inside contact task program


7-13

• Inside contact task program is performed after completing performance of scan program. Although performance condition of inside contact task program is occurred at scan program or task program (positive period, Outside contact), it is not performed immediately but performed after completing performance of scan program.

• Inside contact task checks at the completed performance point of scan program. Therefore if inside contact task performance condition is occurred and disappeared(if doing OFF→ON→OFF assigned contact) by scan program or task program (positive period, Outside contact) during “1 scan”, task doesn’t perform cause performance condition is not detected at performance condition checking point.

7.4.6 Verification of Task Program Verify below significant items after making task program. (1) Is the setting of the task proper?

Scan time will become longer or irregular if task occurs more than necessary or various tasks within one scan occur simultaneously. If task setting cannot be changed, check the setting value of the watchdog time with consideration of scan time that is possible to occur.

(2) Is the task priority well arranged?

Check the case of task required simultaneously and then recheck task priority with it.

(3) Do you make the task program short? If the performance time of the task program is long, it causes that scan time becomes longer or irregular or crush of task program can be occurred. Make the performance time short if it is possible.

(4) Is there any effective to other program due to performance result of task?

If scan program and task program share input image, direct parameter (%M) and global parameter, check that the process results of the task programs effect scan program. It has to be paid more attention, if using “standby task process function” or spiriting scan program.

Refer to “Example of Scan Time Calculation” of “7.8 Scan Time” for process speed of scan program and task program.

8.1 System Operation

8.1.1 Program Preparation (1) Program Preparation

Prepare the program using GMWIN. (For detailed, see ‘GMWIN User’s Manual’.)

(2) Program Transmission

• Transmit program to PLC using GMWIN. • Mount the memory module having operation program.

8.1.2 Operation Method For PLC operation, there are the following methods.

(1) Using Local Key:

Download the program in REM mode and then set Front key to ‘RUN’.

(2) Using GMWIN: Set Front Key to ‘REM’ and than select ‘RUN’ in ‘On-line Menu’.

(3) By Power Input: Set Front Key to ‘REM’ and power on. If key set to ‘REM’ and previously Remote ‘RUN’ mode, operation started immediately after power on.

(4) Restart using Reset Key: There are ‘RESEt’ and ‘OVERALL RESET’.

• RESET: Press and release RESET switch in front of CPU module. ‘rESEt’ will be displayed in front. Operates in the same operation with power ON/OFF.

• OVERALL RESET: If pressing RESET switch in front of CPU module more than 5 seconds, ‘rSt c’ will be displayed in front. If releasing switch, restarted with COLD RESTART.

8.1.3 Initial Operation This describes system setting and operation for initial operation of redundant system.

(1) According to I/O usage, set Switched I/O, Redundant I/O and Stand-alone I/O. (2) Prepare program block separately as shown in para. (1) if possible. (3) Set base as shown in para. (1).(Set in the unit of base in Redundant Parameter) Ex.) Base 0:Redundant, Base 1:Redundant Base 2:Switched, Base 3:Stand-alone (4) Set I/O redundant circuit in redundant parameter. (5) Complete configuration and then run compile. (6) Download the program into A Side. (7) With B Side stopped, run trial operation of A Side.


8-2

(8) Set B Side at RUN and make it stand-by. (9) Stop A Side and run back up trial of B Side. (10) If necessary, save the program of each CPU at memory module. (11) Start normal operation as follows.

• Start first the side to be operated as master referring to ‘6.3 Redundant System Operation Mode’(this time, if Stnby displayed at CPU, restart using reset key) and after master started in normal operation, start standby side and make it redundant operation.

8.1.4 Operation Participation

8.1.4.1 Operation Participation

It means the state that standby is participated in redundant operation during operation of master. Standby is synchronized with master as follows.

(1) Initialization of CPU (2) Check of Redundant Composition (3) Transfer of invariable data from master (4) Transfer of variable data from master (5) Check of synchronization with master (6) Participating in operation at the same time with master

Remarks

• (1),(2),(3) are processed in separately to do within delay time of about 50ms at each scan of master. • (4),(5),(6) shall be processed within one scan of master and within delay time of max. 50 ms. (If operating variable exceeds the standard, its delay time may be over 50ms. See 8.5.3 Delay Time in Redundant Operation’.)

8.1.4.2 Standby Operation Participation Details

This describes the detailed operation when standby participated in .

(1) Power On • Check during operation of master • Standby Entry Mode • CPU Self Diagnosis • Transfer of program from master(write in RAM, Memory Module) (2) Check of Redundant Composition • Check Switched I/O Access • Transfer of switched I/O module information from master • Scan redundant I/O module information installed at standby side • Comparison with I/O parameter (3) Transfer of invariable data from master • Transfer of flag from master(if necessary, divided into several scans) • Check the flag not changed and then proceed to step (4) (4) Transfer of variable data from master • Some User Data area and system buffer


8-3

(5) Check synchronization with master • Synchronizes the operation information in CPU. (6) Participation in operation at the same time with master • Run redundant operation from input refresh

8.1.5 Operation Condition

8.1.5.1 Normal Operation

• If power applied, master CPU module checks system configuration. If power applied late in extended base, front display shows checking base such as ‘Eb xx’ until power on. In STOP mode, an error occurred after 10 seconds’ wait.

• After modifying the program, initial operation starts in Cold Restart.

• When restarting the system stopped in normal operation, do as parameter setting. There are Mode key, GMWIN, Power OFF, and reset.

• If restarting the system of Warm Restart in Cold Restart Mode, Use Reset Key or ‘OVERALL RESET’ of GMWIN.

• If stopped by errors during operation, restart will be determined according to the type of error and remedy (See ‘Chapter 13. Program Troubleshooting’).

8.1.5.2 If I/O Skip set

• Exclude skip setting module from the operation. Therefore skip troubleshooting. If skip released during operation, it will be included in operation normally. For details, see ‘9.2 I/O Skip’ and 9.3 ‘Module Replacement During Operation’.

8.1.5.3 If Trouble Mask set

• If trouble mask set, it will be included in operation. Perform troubleshooting. Continues to operate even if module type inconsistent error occurred in initial start. For details see ‘9.1 Trouble Mask’.

• If mask set at overall base with power off, CPU waits for power on in standby.

8.2 I/O Forced ON/OFF

8.2.1 Forced ON/OFF Setting • Set Forced On/Off in accordance with areas of Input (I) and Output (Q).

• Set Input and Output respectively and operate from when ‘Forced I/O Setting Permission’ set.

• If actual I/O module not mounted, setting is enabled. (For detailed information, see ‘GMWIN User’s Manual’.)


8-4

8.2.2 Forced ON/OFF Processing Time and Method

8.2.2.1 Forced Input

• Input(I) updates Input(I) image area by replacing contact data set in Forced On/Off with forced data out of those read from input module at input refresh. User program runs the operation with forced data at forced contact.

• When setting forced input of input contact in triplex configuration, designate input position of redundant base.

Remarks

• If forcedly controlling the contact of switched base from triplex input, input value is not changed and an error detected in its contact. • If controlling the input used for system monitoring such as output feedback, system error can be occurred.

8.2.2.2 Forced Output

• Output(Q) outputs the data by replacing contact output set in Forced On/Off with forced data out of output image data having operation results at output refresh after a completion of user program operation. • Redundant output designates output position at redundant base and both of two outputs will be output simultaneously.

8.2.2.3 Forced On/Off Processing Area

• Input (I) and Output (Q) area for Forced On/Off is designated bigger than actual area. If designating remote I/O with this area, forced On/Off can be used equally with basic I/O area. Remarks

• In case of OFF -> ON, Operation Mode Change and Reset Key operation, forced On/Off setting data previously set is retained in PLC. • If program download and backup broken, forced On/Off setting data will be erased. On/Off setting data will be erased in operating program memory even if restarted with flash memory program. • To set new forced data from start, release all setting of Input and Output respectively using ‘ERASE’ key.


8-5

8.3 Immediate I/O This can be used effectively when reading immediately input contact during program operation or outputting immediately operation results at output contact.

8.3.1 Immediate Input In case of Immediate Input, use 'DIREC_IN' function and if completed, Input (I) image area will be updated and applied immediately at subsequent operation.

8.3.2 Immediate Output In case of Immediate Output, use 'DIREC_O' function and if completed, Output(Q) image area data

will be immediately output at output module with operation results. Redundant output designates output position at redundant base and both of two outputs will be

output simultaneously.

8.3.3 Forced ON/OFF In case of forced I/O processing, forced On/Off setting is valid.

8.4 Memory Structure CPU module contains two kinds of memory available for users. One is program memory saving user’s program for establishing system and the other is data memory saving data during operation.

8.4.1 Program Memory Structure The following table describes items and size of program memory.

Item Size

Overall Program Memory Area 512kbyte System Area: • System Program • Back up

13kbyte

Parameter Area: • Basic Parameter • I/O Parameter • Highway Link Parameter • Interrupt Setting Information • Redundant Parameter

35kbyte

Program Area: • Scan program • Task program • User defined function/function block • Standard Library • Access Variable • Variable Initialization Information • Retained Variable Designation Information

464kbyte


8-6

8.4.2 Data Memory Structure The following table describes items and size of data memory.

Item Size

Overall data memory Area 512kbyte System Area: • I/O Information Table • Forced I/O Table • Module Skip Table and etc.

50kbyte

System Flag Area 4,096byte

Input Image Area(%IX) 4,096byte

Output Image Area(%QX) 4,096byte

Direct Variable Area(%M) 0~64kbyte

Symbolic Variable Area (Max.) 256kbyte - Direct Variable Area

Redundant System Flag Area 254kbyte

Stack Area 4,096kbyte 1) System Area

Saves CPU module self-producing data for system management and system control data through GMWIN.

2) System Flag Area As saving area of user flag and system flag as shown in Chapter 11, users control this with flag name.

3) Input Image Area Where input data read from input module saved in automatically. Entire range between %IX0.0.0 and %IX63.7.63 but available between %IX0.0.0 and %IX15.7.63 for actual input module area. The area without actual module can be used freely in program. Especially, conveniently used to save data of remote input through highway link.

4) Output Image Area As memory of operation results, saved data will be output automatically through output module. Entire range between %QX0.0.0 and %QX63.7.63, but available between %QX0.0.0 and %QX15.7.63 for actual output module area. The area without actual module can be used freely in program. Especially, conveniently used to save data of remote output through highway link.

5) Direct Variable Area Where accessible to direct memory data through variable name previously designated by system such as %MX0, %MB0, %MW0, %MD0, %ML0, and etc. Users will set the capacity in ‘OPTION’ menu of GMWIN.


8-7

6) Symbolic Variable Area

Variable made in programming by users, e.g. as data memory with name designated, there are general variable, global variable, and instance memory. The variable used in program block is located in ‘PB Instance Memory’ of desired program. One used in function block is located in ‘FB Instance Memory’. The max. size of PB instance memory is 32K Byte and if exceeding the max. size, program block can be divided and global variable used.

8.4.3 Resource Global Variable Processing

8.4.3.1 Resource Global Variable

Resource Global Variable means that sharable between programs and corresponds to Direct Variable and Symbolic Variable designated as Resource Global. These have one memory physically. That is, these are located in ‘Direct Variable Area(%M)’ and ‘Symbolic Variable Area’. Direct Variable can be used directly in each program and symbolic one used after designating those with the same name as ‘VAR-EXTERNAL’. Resource Global Variable can be written in applicable variable immediately when program performed. There are no problem between programs in scan task while processing sequentially, there may be confusion of data due to intervention of task program while running scan program. Take considerations of the followings in programming.

(1) When using resource global variable, don’t ‘Write’ the same variable in more than two task programs. In other words, do ‘write’ in one task and ‘read’ in required location unconditionally.

(2) When doing program block, save the value of global variable in Local Variable and then do program using Local Variable value. Then, homogeneous data will be hold in program block even if global variable value changed by task during program operation.


8-8

8.5 Scan Time This means the time elapsed after scan program of one time until restarting of scan program.

8.5.1 Scan Time Calculation Scan Time means the sum between processing times of user’s scan and task programs and PLC internal processing time. Scan time is calculated as shown in the following equation.

8.5.1.1 Scan Time Calculation Equation

• Scan Time = Scan Program Processing Time + Task Program Processing Time + PLC internal processing time • Scan Program Processing Time = Processing time of user’s program not designated as Task Program • Task Program Processing Time = Sum of task program processing time treated for one scan • PLC Internal Processing Time = Self diagnosis time + I/O refresh time + internal data processing time + Communication service processing time

Scan time can be varied greatly due to task program operation, I/O redundant composition and communication data treatment.

Remarks • Scan Time can be increased excessively when standby system participated in operation. • Scan Time is longer than stand-alone operation during redundant operation.

8.5.1.2 Scan Time Related Flag

Scan Time is saved in system flag area. • _SCAN_MAX : Max. Scan Time (1ms Unit) • _SCAN_MIN : Min. Scan Time (1ms Unit) • _SCAN_CUR : Current Scan Time (1ms Unit) To measure processing time of task program for calculating scan time, enter task number to be measured in '_STSK_NUM' of system operation information flag in Variable Monitor Mode and monitor '_STSK_MAX, _STSK_MIN, and _STSK_CUR'.

8.5.1.3 Ex. Of Scan Time Calculation

In case of users program structure as shown below (see 7.4.7), how to calculate max. scan time is as follows. • Task: T_SLOW ( Interval := T#30ms, Priority := 2, Task No. : 0 ) PROC_1 ( Single := %MX0, Priority := 3, Task No.:48 ) E_INT1 ( Interrupt:= 0, Priority := 1, Task No.:32 )

(1) With only scan program(S0,…S9) run excepting task program, measure scan time (_SCAN_MAX) while doing communication service through communication module and monitor through GMWIN.

(2) To measure running time of positive period program, start program including positive period task program, register '_STSK_NUM, _STSK_MAX, _STSK_MIN, _STSK_CUR' flag in GMWIN Variable Monitor Mode, enter Task Number ‘0’ at '_STSK_NUM’ and then measure the value of ‘_STSK_MAX’.

(3) Start the program including single task program, enter task number ‘48’ at '_STSK_NUM’, start task in GMWIN (1->%MX0), and then measure the value of _STSK_MAX’.

(4) Start the program including interrupt task program, enter task number ‘32’ at '_STSK_NUM’, turn ON the input of interrupt module, and then measure the value ‘_STSK_MAX’. If the max. run time being Tscan(S0~S9) = 80 ms, Tp1 = 4 ms, Tp2 = 7 ms,

(5) Tp3 = 1 ms, basic san time will be 87 msec (Tscan + Tp2) if single task started during program operation and scan time be 95 msec(Tscan + Tp2 + Tp1 x 2) with two times positive period occurred. If external task occurred three times, scan time will be 98 msec(Tscan + Tp2 + Tp1 x 2 + Tp3 x 3) and max. scan time be 102 msec(Tscan + Tp2 + Tp1 x 3 + Tp3 x 3) with positive period run once more. If external task can be occurred within 102 msec, add its processing time and review the number positive period occurred. (See 7.4.7 Ex. Of Program Composition and Processing’ timing diagram)

8.5.2 Scan Watchdog Timer (1) Scan Watchdog Timer is used to detect operation delay due to an error of users program. Detection time of Scan Watchdog Timer is set at basic parameter. (2) Scan Watchdog Timer monitors Scan Elapsed Time during operation and if sensing excessive detection time, PLC immediately stops operation and perform the followings.

Overall Output OFF Set Error LED of CPU Module to ‘ON’ Display ‘E 040’ at 7 segment of CPU Module. (3) If Scan Watchdog time is expected to exceed in a specific program process during user’s program operation, use ‘WDT_RST’ function. If ‘WDT_RST’ function started, initialize the elapsed time of watchdog timer and restart from 0. (4) Power Input, Manual Reset Switch or Mode Change to STOP can be used to exit scan error.

8.5.3 Delay Time in Redundant Operation

8.5.3.1 Delay Time in Redundant Operation Entry

To entry redundant operation among single operations, scan time will be increased excessively when standby CPU activated. Not increased over 50ms during program transmission. Can be increased over 50ms as long as data transmitted as a package. If the sum of symbolic variable and %M area setting being within 10K byte, delay time can be within 50ms and increased about 2ms per 1K byte if exceeded.

8.5.3.2 Scan Time in Redundant Operation

Scan time can be increased in redundant operation basically compared with single operation and greatly increased according to simultaneous operating number within one scan of special module FB and communication FB. Communication FB can choose sequential operating method.

Remarks

Scan Time will be increased excessively to entry Redundant Operation from Single when standby CPU activated.

8.6 RTC : Real Time Clock This PLC CPU module is basically mounted with RTC. RTC provides ‘Time Display Flag’ available in program and displays the time on Fault Report. It also provides hot restart time measuring when Hot Restart used. In case of a power failure more than 20ms or Power OFF, clock continues operation by battery back up. RTC time value updates at system flag area every scan. RTC time value is enabled in Read/Write through GMWIN (See ‘PLC Information’ of ‘On-line’ Menu of GMWIN).

8.6.1 RTC Internal Data Built-in Clock IC has the characteristics as shown in the following table.

Item Data

Year 4 digits in solar calendar

Month 1 ~ 12

Day 1 ~ 31

Hour 0 ~ 23 (24 hours)

Min. 0 ~ 59

Sec. 0 ~ 59 1/100 seconds 0 ~ 99

Day of the Week 0 ~ 6 (Monday ~ Sunday)


8-11

If using time in Operation Program, do programming using User Flag ‘_RTC_DATE’, ‘_RTC_TOD’, ‘_RTC_WEEK’ available in the above table. It can be used in system control such as Start/Stop and Time Stamp of operation history, and etc. ‘_RTC_TIME[n]’, provided as system flag, is provided in BCD form to facilitate data transfer to simple display device or the equipment where time data type not handled.

8.6.2 RTC Time Error There can be errors of the max. ‘±5 seconds/1 month’ according to operating environment of PLC.

Remarks

If battery back up stooped more than 30 min., RTC may stop its operation. Time data was not set when the product purchased. Set and then use time data in system setup. If writing time data in RTC besides the range specified in the above table, it doesn’t operate normally.

( Ex. : 13 Month 32 Day 28 Hour ) If RTC error found, _RTC_ERR of system flag _CNF_WAR turns ON.

If RTC error corrected, _RTC_ERR of system flag _CNF_WAR turns OFF(For error of RTC by CPU, see _CNF_A,B_WAR 의 _RTC_A_ERR, _RTC_B_ERR). RTC stop or error can be occurred due to battery error and etc. If writing new time value in RTC, RTC error

will be resolved.

8.7 Precautions when using special module

GLOFA system provides convenience and high performance of program compared with the previous method when using special module. Take some precautions when establishing the system. Make you understood what the following describes and review the applicable system.

8.7.1 Special Module Programming To make the program simple and prevent programming error, it is provided with function block in separately at each special module.

(1) Function block takes a role as interface between data of users program and special module,

monitors the operation of special module, and displays errors. Special error detection program is not required.

(2) Function block consists of ones for ‘initialization’ and ‘controlling’ the operation of special module.

(3) Function block is provided with one for single module(attached to switched base) and for redundant module(attached to redundant base) according to mounting method.

Remarks

For detailed function block, see ‘Appendix 2.3 Special module function block table’ of this manual and user’s manual of special module.


8-12

8.7.2 Special Module Initialization To define the operation characteristics of special module, do program using ‘Initialization’ function block. Generally, data range, resolution and filtering for channels are designated. You have only do once when starting system.

(1) When system started, initialization shall be completed before master CPU performs scan

program and so done in restart program (initialization task program). But function block required to change set data during operation can be done in general program.

(2) Standby CPU doesn’t perform initialization program. Special module, which is located at redundant base and controlled by standby CPU among redundant special modules, performs module initialization in the method of automatically transferring the information of special module to master.

Remarks

• Special module of switched base can cause errors in a power failure of applicable extended base unit. If programming to override errors and proceeds to operation, special module can be restarted using GMWIN after a recovery of power(See ‘Special Module Initialization’ of 9.3.3 Switched Base Replacement’.

8.7.3 Special Module Control To control the operation of special module, do programming using function block to be controlled for each module. This can be done regardless of the position of program. But it is recommended to handle input and output with one function block through overall scan program for efficient system management and use data memory for operation inside of system.

(1) Control of Single Module • Special Module attached to Switched Base has the same external connection and program method with that of single system. (2) Control of Redundant Module

• Analogue output module has the same program method with that of single system. For connection method and use, see ’10.1.3 Redundancy of Analogue I/O Module’.

• Function block for analogue input module provides both two input data. Check module state, channel state and data value and choose one selectively on the program. For connection method and use, see ’10.1.3 Redundancy of Analogue I/O Module’.

Remarks

• It is recommended to use array type function block rather than single channel to minimize the scan time. • If using hot restart, output the standard of STOP mode until new data used in the program. If writing every scan data in special module, immediately normal output can be done. But when output data value changed or written periodically, standard output can be done until that time. To keep the continuity of output, it is recommended to output the data one time in hot restart program after initialization of special module.

8.7.4 Module Replacement During Operation If replacing extended base or module during system operation, the initialization of special module and data recovery is enabled using GMWIN. If a failure of extended base or power OFF, the system continues operation normally and proceeds to operation without restart of CPU module in ON->OFF->ON(See ‘9.3 Module Replacement during Operation’).

8.9 Flag For displaying outside fault This flag is provided for users to detect fault of outside equipment and perform system stop and warning. If using this flag, outside fault will be displayed without complex program and fault position be monitored without special device(GMWIN and etc.) or source program.

8.9.1 Detection and Classification of Outside Fault Outside fault can be detected by user’s program and classified into Heavy fault(error), which stops PLC operation according to detected fault, and light fault(warning), which continues operation of PLC and only displays fault state. ANC_ERR[n] flag will be used in heavy fault and ANC_WB[n] flag used in light fault.

8.9.2 Heavy Fault of Outside Equipment When heavy fault detected in user’s program, if classifying user’s defined error type and writing the value excepting 0 in system flag _ANC_ERR[n], a fault displayed in ANNUN_ER of CNF_ER, representative system error flag, when a completion of scan program. Then, PLC turns off all output modules and becomes an error equally with PLC self-detection. In case of fault, users can find the cause of fault using GMWIN or by monitoring ANC_ERR[n] flag. ANC_ERR[n] has 16(n : between 0 and 15) fields and classifies fault status greatly. If is able to write fault number designated temporarily by users in each field and the number can be between 1 and 65,535.

Ex.) Error Detection MOVE 10 _ANC_ERR[0]

8.9.3 Light fault of Outside Equipment When light fault detected in user’s program, turns On the flag of desired position according to the usage out of system flag ANCWB[n]. When a completion of scan program, search from ANC_WB[0] and in case of warning, it will be displayed in ANNUNWR of CNFWAR, system warning representative flag, and light fault number of outside equipment will be written from ANCWAR[0] to ANCWAR[7] according to occurrence order. In case of warning, users can find the cause of fault using GMWIN or by monitoring ANCWAR[n] and ANCWB[n] flag. If light fault removed from outside equipment, e.g. after a completion of user’s program, those removed from _ANC_WB[n] will be automatically deleted from _ANC_WAR[n] flag and if all removed, _ANNUN_WR display of system flag _CNF_WAR will be reset. Ex.) Error Detection _ANC_WB[10]


8-16

-- Ex. Of Light Fault Detection and Flag Display of Outside Equipment --

During user’s program operation, if system error detected with user’s program and set _ANC_WB[10] to ON, complete operating scan, and _ANNUN_WR 과 _ANC_WAR[0..7] will be shown as in the left. After the next scan completed, if Nos. 1, 2, 3, 10, 15, 40, 50, 60, and 75 set to ON, _ANC_WAR[n] will be shown as in the left. No. 10 has lower priority than Nos. 1, 2, and 3, but set to ON in the previous scan(occurred in advance), so it will be written before _ANC_WAR[n]. Although _ANC_WB[75] set to ON, the warning occurred in advance will not be displayed due to _ANC_WAR[n] full. After the next scan completed, if Nos., 2, 3, 15, 40, 50, 60, 75 set to ON, _ANC_WAR[n] will be shown as in the left. Because No. 10 warning removed, it will be deleted from _ANC_WAR[0] and the content of _ANC_WAR[1..7] be get ahead of. After data moved, _ANC_WAR[7] will be empty and _ANC_WB[75] be written in _ANC_WAR[7]. If all warnings displayed in _ANC_WB[n] during operation, _ANNUN_WR and _ANC_WAR[n] will be shown as in the left.

Remarks

When light error detected, error will not be displayed in CPU Module.

_ANNUN_WR = 1 _ANC_WAR[0] = 10

_ANC_WAR[1] = 0 _ANC_WAR[2] = 0 _ANC_WAR[3] = 0 _ANC_WAR[4] = 0 _ANC_WAR[5] = 0 _ANC_WAR[6] = 0 _ANC_WAR[7] = 0

8.10 Operation in Instantaneous Power Failure CPU Module detects instantaneous power failure when input power off or the voltage of input power lower than the specified. If CPU detected instantaneous power failure, perform operations as follows.

8.10.1 Instantaneous Power Failure less than Permissible 20ms (1) If instantaneous power failure detected, temporarily stop operation with output state remained. (2) If instantaneous power failure released within 20ms, proceeds to operation. (3) When instantaneous power failure occurred within 20ms, operation delay time will be ‘power failure

time +8~20ms’. Also if instantaneous power failure released, restart operation after delay of 16 to 28 ms for input normalization of AC input.

(4) If operation stopped due to instantaneous power failure, scan watchdog timer continues counting. For example, If 15ms instantaneous power failure occurred with scan watchdog time set to 200ms and scan time to 190ms, scan watchdog time error will be occurred. (5) If operation stopped due to instantaneous power failure, timer counting and positive interrupt timer

counting continues operation(For task in instantaneous power failure, see 7.4.2.3 System Start and Task Performance in instantaneous power failure).

8.10.2 Instantaneous Power Failure Exceeding Permissible 20 ms When a power failure more than 20ms occurred, PLC will be restarted. Power module can supply CPU module with normal DC power up to 20ms after AC_Fail. This time, CPU module keeps stop and output state. If AC power not recovered for 20ms, CPU module turns off output and becomes in standby. In subsequent power recovery, restart operation as in normal power on.

8.10.3 Instantaneous Power Failure During Redundant Operation Factors of instantaneous power failure are as follows in redundant system.

(1) Instantaneous power failure of master CPU (2) Instantaneous power failure of standby CPU (3) Instantaneous power failure of extended base

8.10.3.1 Power Failure of Master CPU

• If instantaneous power failure released within 20ms, proceeds to operation. • If power failure not recovered exceeding 20ms, master stops operation and standby CPU is switched to master to proceed to operation

8.10.3.2 Power Failure of Standby CPU

• If instantaneous power failure released within 20ms, proceeds to operation. • If power failure not recovered exceeding 20ms, master proceeds to operation and standby CPU stops operation.

8.10.3.3 Simultaneous Power Failure of Master/Standby CPU

• If instantaneous power failure released within 20ms, proceeds to operation. • If power failure not recovered exceeding 20ms, overall redundant system stop operation. • When power recovered, the power of master shall be recovered to restart system.

8.10.3.4 Power Failure of Extended Base

• To prevent abnormal input and output even in instantaneous power failure of extended base, stops operation and monitors instantaneous power failure as in CPU power failure.

• Power Failure of Extended Base : If instantaneous power failure released within 20ms, proceeds to operation and if not recovered exceeding 20ms, stops operation.

• Power Failure of Redundant Base(Only one side): If instantaneous power failure released within 20ms, proceeds to operation and if not recovered exceeding 20ms, excludes the base and proceeds to operation

• Power Failure of Redundant Base(Both side):: If instantaneous power failure released within 20ms, proceeds to operation and if not recovered exceeding 20ms, stops operation.

• If power recovered in extended base after instantaneous power failure exceeding 20ms, system will be restarted.

Remarks

If instantaneous power failure occurred in redundant system, its operation will be delayed about 20ms to detect the fault.

Chapter 9. Error Remedy 9.1 Fault Mask

9.1.1 Usage and Operation of Fault Mask Fault Mask is used to override and proceed to operation of program if fault occurred in designated module or base during operation. Module or Base designated with fault mask performs update of normal I/O data and trouble check until fault occurred. If fault occurred in module or base with fault mask set during operation, CPU module flickers front display and program proceeds to operation. It will not be displayed in error representative flag and GMWIN. If detailed flag monitored in the area with fault mask set, error can be found.

9.1.2 How to Set Fault Mask (1) Fault Mask is able to be set for fault of module or base and user defined error(_ANNUN_ER). (2) Module fault mask can be set directly by GMWIN on-line menu(fault mask setting) or user’s program and by parameter in ‘Redundant Parameter’ setting menu of programming. (3) 12-slot base can be recognized as subsequent 2 base, so all of two base areas should be set.

9.1.3 By Flag Fault Mask Flag can be preset before error occurred and set by error task program started when error occurred.(See ‘System Fault Mask Flag’). Remarks

• If removing cause of errors without error flag deleted in CPU module, system stops operation. Before releasing of fault mask flag, check error flag.

9.1.4 By Parameter In programming, it can be set in parameter, compiled with program, and then downloaded. Parameter setting will be copied to fault mask flag in first initialization of system after download of program. In spite of parameter setting, flag can be changed using flag control during operation.

Remarks

• Modules set in Redundant Base continues operation if any one failed. When corresponding two modules failed, to continue operation, set fault mask. • When Power OFF->ON, Operation Mode changed and Reset Key operated, fault mask setting data set previously would be retained and performed in PLC. It is able to be deleted using GMWIN or program. • Data of Fault Mask flag are updated with parameter data as follows. 1) Restart operation after download of program using GMWIN 2) If operating program memory has different program with flash memory module and restarts operation with memory module program loaded into program memory. 3) If memory backup broken due to drop of battery voltage


9-2

9.2 I/O Skip(I/O Module, Extended Base Operation Miss Designated)

9.2.1 Usage and Operation of I/O Skip I/O skip function excludes the designated module and base from operation. Designated module and base stops trouble check and update of I/O data from the time designated. It can be used for replacing base during operation and temporary operation with fault excluded from. For module replacement, see 9.3 Module Replacement during Operation.

9.2.2 I/O Skip Setting and I/O Data Processing (1) Skip can be set in the unit of module or base. It is set in on-line menu(I/O Skip) of GMWIN. For detailed, see ‘GMWIN User’s Manual’.

(2) 12-slot base can be recognized as subsequent 2 base, so all of two base areas should be set.

(3) Input(I) Image stops input refresh and keeps previous value of skip setting. But, image control is valid by Forced On/Off. Actual output of output module turns OFF in skip setting, but output(Q) image varies to the operation

of user’s program regardless of skip setting. Output value control of output module is disabled after skip setting.

(4) Skip function will be run equally when immediate I/O function used. Remarks

• When Power OFF->ON, Operation Mode changed and Reset Key operated, skip setting data set previously would be retained and performed in PLC. Skip function is able to be released using GMWIN or program. • Skip setting data are deleted if any of the following occurred. 1) If restarting operation after download of program using GMWIN 2) If operating program memory has different program with flash memory module and restarts operation with memory module program loaded into program memory. 3) If memory backup broken due to drop of battery voltage

9.2.3 Application to Redundant System When installing in Redundant Base, Both of A-side and B-side can be set and only one as required.


9-3

9.3 Module Replacement During Operation

9.3.1 General of Module Replacement During Operation Module Replacement can be varied in accordance the position of module to be replaced during redundant operation. It is divided into switched base and redundant base. First check the followings when replacing the module (1) If stopping CPU system and replacing module,

When any CPU stopped, check there is no error or warning at the side to perform one-sided operation. For example, in case of abnormal communication line at the side to operate, communication can be disconnected when changed into One-Sided Operation. (2) If using I/O redundancy

If stopping some or overall faulty equipment, first check for abnormal. Check there is no contact error in switched base or the part performing one-sided operation during output. If no error in contact of switched base, first resolve the fault of switched base prior to repair of redundant base. REMARK

• In GMR Redundant system, it is possible to replace the module during operation. But special precautions should be taken that it can cause mis-operation of overall system. • 12-slot base can be recognized as subsequent 2 bases, so skip and fault mask should be set for all of two base areas. • Always set fault mask sequentially during replacement to prevent mis-operation of replaced module or overall system.

9.3.2 Replacement of CPU redundancy Stop operation of desired CPU system and then replace CPU redundant.

9.3.2.1 Replacement Sequences of CPU Module, Communication Module, Remote Interface Module

(3) Set ‘OPER’ switch of remote I/F Module to ‘N’. (4) Turns off the base. (5) Replace module. (6) Reapply the power. (7) Set ‘OPER’ switch of remote I/F Module to ‘Y’. (8) Release skips setting of the base in GMWIN. (9) Check it for normal operation(Check Error Detailed Flag, see ’9.1.1’). If replacing with the other module due to faulty replaced module, proceed to (1). (10) Release fault mask and return to normal operation. Remarks

• If power down without switch control of interface module, overall system becomes AC_Fail state. Take precautions of it.

9.3.4.3 Module Replacement after Module Operation Stopped(Digital Module)

When replacing the module in certain operation, exceptional working is enabled as follows.

1) Module Replacement of the base that consisted of only digital I/O module. (1) Perform skip setting to base to replace module in GMWIN. (If replacement module belong to A CPU system, set only A and if belonged to B CPU, only B). (2) Set Fault Mask to the same base in GMWIN. (3) Replace module. (4) Release skips setting of the base in GMWIN. (5) Check it for normal operation(Check Error Detailed Flag, see ’9.1.1’). If replacing with the other module due to faulty replaced module, proceed to (1). (6) Release fault mask and return to normal operation.

Remarks

• In these procedures, I/O module operated in the same base can cause wrong data instantaneously. • Due to an error of replaced module, the other fault of the same base can be detected. It is safe to set fault mask at overall base.

2) Digital Module Replacement of the Base that consisted of combined Special Module Replace as in the above (1) ‘Module Replacement of the base that consisted of only digital I/O module’. Remarks


3) Replacement of Special Module (1) Perform skip setting to base to replace module in GMWIN. (To prevent master changed during module replacement, set skips to A CPU and B CPU systems regardless of master CPU. (2) Set Fault Mask to the same base in GMWIN. (3) Replace module. (4) Perform initialization in GMWIN for replaced module. (5) Release skips setting of the base in GMWIN. (6) Check it for normal operation(Check Error Detailed Flag, see ’9.1.1’). If replacing with the other module due to faulty replaced module, proceed to (1). (7) Release fault mask and return to normal operation. Remarks


4) Initialization of Special Module • If replacing with faulty CPU off, read default from operating special module and perform initialization automatically. • If replacing with I/O partially off, see 9.3.3. Initialization of Special Module.

9.4 Error Remedy

9.4.1 Segment of Errors Errors consists of error due to H/W failure of PLC, system configuration error, operation results error, and etc. When errors occurred, operation stops(see Chap. 13 Troubleshooting), operation can be continued by flag setting and error program.

(1) PLC Hardware Error

(2) System Configuration Error (3) Operation Error of User’s Program (4) Error detected by User’s Program

9.4.2 Standard Error Remedy When an error occurred, PLC system records error content in flag and continues or stops operation in accordance with error content and parameter setting. If an error occurred corresponding to ‘System Error Flag’ after scan program performed, system automatically performs error remedy program. Users can take an action against errors by making error remedy program and parameter. If error remedy program not prepared, it is standard to stop operation when errors occurred. (1) PLC Hardware Error

If hardware error occurred in CPU module, power module, and etc., system stops operation.

(2) System Configuration Error It is occurred when hardware configuration different between PLC and software. If errors occurred, system stops operation.

(3) Operation Error of User’s Program Errors occurred during user’s program operation could cause operation error to be displayed in error flag and continue operation. If operation time exceeds scan watchdog time or attached I/O module controlled normally, system stops operation.

(4) Error detected by User’s Program Errors occurred in external control equipment and detected by user’s program. If errors detected, system stops operation.

9.4.3 How to change by users If the above errors occurred, users can change operation using error operation program, fault mask parameter and flag control through program tool to do in the method besides standard. (1) PLC Hardware Error

If hardware error occurred and CPU module, power module, and etc. not operated normally, system can’t change the operation.


9-9

(2) System Configuration Error

Error occurred when hardware configuration different between PLC and software. If errors occurred in initial check of cold and warm restart, system stops operation. If configuration changed such as module loss during operation but flag mask flag set to desired slot, it continues operation.

(3) Operation Error of User’s Program Errors occurred during user’s program operation could cause operation error to be displayed in error flag(_ERR,_LER) and continue operation. User’s can stop operation referring to error flag. This time, error task program will not be started. If error occurred when attached I/O module not controlled normally, it continues operation by controlling error task program and fault mask flag by parameter.

(4) Error Detected by User’s Program When errors detected in external control equipment(Heavy error detection error of external equipment), it continues operation by controlling error task program and fault mask flag by parameter.

9.4.4 Detailed Error Task

9.4.4.1 Error Task Operation

If errors detected by CPU during program running, ‘_ERR_SYS’ task will be raised. This time if the program prepared with ‘_ERR_SYS’ task as operating condition, it continues programming(See 7.2 How to run program).

9.4.4.2 Error Remedy in CPU

(1) After a completion of scan program, perform system trouble check in END and displays at desired error flag if errors occurred. (2) If the program registered with error task as operating condition, continue programming. (3) If there is any error in error flag, system stops. But if the error set to corresponding fault mask flag in user’s program performed in (2), system continues operation(If setting fault mask flag, it is safe to set skip flag together.)

9.4.4.3 Error Task Operation Flag

(1) I/O Module Error: _IO_DEER, _FUSE_ER, _IO_RWER, _SP_IFER, RIQ_ER (2) External Equipment Error: _ANNUN_ER For detailed error, see ’11.2 System Error Flag’. Remarks

• Displayed error flag will not be deleted automatically during operation even if an error removed(Power OFF→ON), • Error flag will not be deleted with Fault Mask Flag set. • With error flag set, ‘_ERR_SYS’ task will be occurred in END of every scan to do programming.

9.4.5 Example of Error Task

9.4.5.1 System Configuration and Operation Setting (1) System Configuration and Operation Setting Digital Module installed at Slot 4 and 5 of No. 1 Extended Base is constructed so that overall system operation might not be stopped when a failure of module occurred for driving operation indicator. If fault mask set, module error flag will be displayed normally. Error task will be performed every scan if an error found. (2) Error Task Program Ex. Among the above program, 16#30 will be indicated as ‘0011 0000’, mask slot in base(See ‘_SLOT_M’ of Fault Mask Flag).

10.1 Principle

10.1.1 Triplexing of Digital Input

10.1.1.1 Check of Digital Input

Read data of the same switch as three input contacts and if data matched with more than two, choose the value as normal data. Three inputs can be read one another instantaneously by the factors of switch position, switch state, wiring, filter delay of input module, and etc., but if no error in input, normal data will be choose after some delay.

CPU determines it to be fault and remove from operation if any input value not changed until the other two changed input data again.

10.1.1.2 Circuit Diagram of Redundant Input

Three inputs are located at Redundant Base A and B and Switched Base respectively. When installing triplex input, multi power and sensor can be applied to increase availability of system. [Fig. 10.1]Triplex Input Circuit

Choose data with more than 2 out of 3 inputs having the same value(Ex %lx2.0.0-A,%12.0.0-B%l1.0.0 in a pair).

10.1.2 Redundancy of Digital Output

10.1.2.1 Check of Digital Output

For output module, wrong output can be occurred due to a failure of output module and element. Error consists of Permanent 0 Output and 1 Output. This time, CPU can verify the fault and cut off the output if faulty. Users shall set feedback input and measuring delay time to find where a fault occurred(set in the unit of 16-point).

10.1.2.2 Circuit Diagram of Redundant Output

When installing redundant output, ‘Single Redundant Output’, ‘Detection of only Fault Contact’, and ‘A/B Discrimination and Load Power Off’ can be applied to increase fault detection and safety of system.

10.1.3 Redundancy of Analogue I/O Module

10.1.3.1 Analogue Input

Analogue Input Module detects the error of input data by user’s program(FB). Redundant FB outputs each module state and data as a result of operation. Users check module and select data. If short of sensor detected in Module(Temperature Sensor Module), error will be detected in FB when sensor disconnected.

[Fig. 10.3] Analogue Input Redundant Circuit Diagram

When signal received from one source as shown in the figure, only voltage input is enabled. If using Current Input and TC, RTD sensor, install two sensors in separately.

10.1.3.2 Analogue Output

10.2 I/O Processing Procedures and Method

10.2.1 I/O Processing Procedures Redundant system has the same operation procedures with that of single system. Processing time of I/O is the same with that of single system and added with Error Elimination by multi I/O during process. The following figure shows flow chart of basic control program.

[Fig.10.5] Flow Chart of Control Program

10.2.1.1 Considerations in I/O Definition

• Signal holding time of the signal entered in PLC has scan time longer than that of PLC. If input changed rapidly, input signal may not be detected and in case of multi input, it can be detected as contact Trouble.

• Take precautions when setting feedback time in feedback setting output.

• The scan time of redundant operation will be longer than that of single operation. While entering

redundant operation of standby CPU, scan time of master CPU will be longer temporarily. Take considerations of it when defining I/O(See 8.5 Scan Time).

10.2.2 Detailed Input Data Processing This describes ‘input image area refresh’ for processing input data as shown in Fig. 10.5 Flow Chart of Control Program. It describes how to extract data from three input values, how to treat wrong input, and how to find fault.

10.2.2.1 Input Refresh Flow Chart

[Fig. 10.6] Input Refresh Flow Chart

(1) Input Data Read Master reads input of Redundant Base and Switched Base that it belonged to and Standby does only input of Redundant Base.

(2) Data Change

Master receives the input of redundant base read by standby and standby does inputs of Redundant and Switched Bases read by master. (If there is single base in A side, transfer single base input into B side). Two CPU modules share the same input data.

(3) Wrong Input Processing

If changed into normal out of those indicated as wrong input in previous scan input check, it will be released and if not changed and exceeded permissible trouble detection time, it will be treated as fault.

(4) Right Input Value Determination

Determines Right input value by majority rules suing three input data).

(5) Wrong Input Detection Compare three input data read from, indicate new wrong input, and monitor it in subsequent scan. If faulty contacts remained, choose Right input value at two contacts and if both two being 1, choose 1. Wrong input detection will not be done in remaining two contacts.

Input Data Scan Start

CPU A.B reads data from inputmodule.

Exchange read data.

Release the indication of ‘WrongInput’ in previous input or treat asfault.

Determine right input value fromthree input data according tomajority rule.

Additionally update ‘Wrong Input’indication according to new data.

• Operation Description of Fig. A)

If three input signals input normally without delay and input data refresh run at dashed point every input, data of input image area %2X2.0.0 will have the same Right input value as shown in the figure.

• Operation Description of Fig. B) Timing diagram of B) shows that three signals input with time delay due to filter delay and etc. In the first scan, three input values become 0 and Right input value be 0. In scan 2, two inputs(%IX2.0.0(A), %IX2.0.0(B)) will be 1, Right input value changed to 1 and remaining input 0(%IX1.0.0)be indicated as ‘Wrong Input’. In Scan 3, three inputs will be 1, right input values be kept at 1, and ‘Wrong Input’ indication released as changed to right input value, e.g. 1. In Scan 4 and 5, there is no change in signal and right input value has been changed to 0 in Scan 6, when input (%IX1.0.0) remained as 1, it will be indicated ‘wrong input’. In Scan 7, as the input indicated as ‘wrong input’ changed as right input value, e.g. 0, ‘wrong input indication’ will be released.

10.2.3.2 Ex. Of Fault Input Processing

The following shows timing diagram related to extract of right input and detection of error used in program operation when a partial fault of input occurred. Wrong input is detected in input refresh and released every 20ms. Perform troubleshooting to determine if error detection setting time exceeded or not at scan END every 20ms. The contacts detected as a fault will be displayed with _RIQ_A_ERR[n], _RIQ_B_ERR[n], _RIQ_C_ERR[n] and verified in ‘I/O Error Detailed Information’ menu of GMWIN.

In Scan 2, the input rather than right input(%IX2.0.2(A)) is indicated as ‘Wrong Input’, but released from wrong input because two inputs being 1 after 20ms.

10.2.4 Detailed Output Data Processing This flow chart provides detailed information for ‘output image area refresh’ as shown in Fig. 10.5. This describes comparison of operation result output data, output from 2 output points, fault detection of output, and auto shutoff of output when faults occurred.

[Fig. 10.9] Output Refresh Flow Chart

(1) Match of Output Data

During redundant operation, compare output data operated in two CPU modules and check if matched with operation result after a completion of scan. In case of different operation result, find the cause and if cause not determined, output it as master data. This time, standby CPU module should be restarted to match with inner data because of having different data in inner data and resulting in wrong results even in continuous operation.

(2) Detection of Fault Contact Each CPU module detects a fault if reading feedback input through input module and after setting time, previous output data not provided with feedback.

Remarks

• If output change time by user’s program being shorter than the sum of signal delay time between

output and input modules, it can cause wrong fault detection.

(3) Output Off

In case of faulty module and abnormal line, CPU module is not able to control abnormal output through output module, which cause a fault, so turn off main power. Then CPU module turns off the power of load by turning OFF master control output contact at parameter designated in user’s program if fault contact detected.

Output Data Processing Start

CPU A.B compare each outputdata and verify if matched with.

Read output data throughfeedback input module and checkoutput contact for disabnormal.

Turn off output power and mark thefault when fault contact found.

(4) Data Output into Output Module

For output module without error, each CPU module outputs data into output module attached to it. Output of switched base will be output by master CPU module.

(5) Save of Output Value To detect fault through feedback input, save output data in memory.

[Fig. 10.10] Feedback Data Detection of Normal Output Signal

The above timing diagram shows that two output signals output the same signal (%QX2.4.0(A), %QX2.4.0(B)) through each output module of redundant output base, feedback output signal(%IX2.5.0(A), %IX2.5.0(B)) through input module of each base, and if error detected, main power turned off by master control output (%QX2.2.0(A), %QX2.2.1(B)) operation. For module configuration and connection, see ’10.2 Digital Output Redundancy’.)

CPU module starts (T0) operation with Master Control Output(%QX2.2.0(A), %QX2.2.1(B)) set to ON after power supply and self diagnosis. Whenever one time operation completed, output operation results at output module. Output data of output module will be output to outside after delay time (Td1,Td2) of output element. Output signal can be received to CPU Module after filter delay time of feedback input module. Then, CPU module checks feedback data after constant delay time(Td3,Td4).

In the above figure, if assumed to output delay 5ms and input delay 10ms, Td3, Td4 becomes 15ms and output signal will be feedback within time delay(Td3, Td4) shorter than setting feedback time 50ms. CPU module checks if there are no errors in output and continues operation with master control output ON.

Remarks

• If feedback time set to 10ms shorter than signal delay time in the above system, CPU may monitor feedback data until 10ms and determine it as a fault.

Chapter 14. Installation and Wiring 14.1 Installation

14.1.1 Installation Environment This equipment can be warranted its reliability and safety when used in the environment specified in general specifications. Take precautions when installing the equipment in order not to miss the environment specified in general specifications. 1) Environmental Conditions

(1) Install in Control Panel available for waterproof and dustproof. (2) Avoid continuous shock or vibration. (3) Do not expose to direct ray of light. (4) Not condensed due to rapid changed temperature. (5) Do not exceed 0~55°C of ambient temperature. (6) Do not exceed 5~95% of relative humidity. (7) No corrosive or flammable gases.

2) Construction

(1) Prevent leftovers entered PLC when machining screw hole or connecting wires. (2) Install where easy to handling. (3) Do not install at the same panel with high voltage equipment. (4) Keep the distance between wiring duct and environmental module more than 100mm. (5) Ground to good noise environment.

3) Radiation Design of Control Panel

(1) If installing PLC in closed control panel, perform radiation design in consideration of its heating as well as heating by the other equipment. If ventilated by means of ventilation fan and commercial fan, it can have an influence on PLC system due to entrance of dust or gas.

(2) It is recommended to install filter or use closed type heat exchanger.

The followings describe how to calculate its own power consumption of PLC system necessary in radiation design.

14-2

2) Power consumption by each Part (1) Power Consumption of Power Module

Power Conversion Efficiency of AC Power Module is about 70% and 30% consumed as heating. Three Seventh(3/7) of output power will be its own power consumption. Therefore, calculated as follows. • Wpw = 3/7 (I5V X 5) + (I24V X 24) (W) I5V : Sum of consumption current in each module DC 5V(inside consumption current)

I24V : Sum of average consumption current of external power supply(DC 24V) such as output module and etc. (Not applicable if DC 24V supplied from outside without PLC power)

(2) Sum of Power Consumption in DC 5V Circuit

If the sum(I5V) of inside consumption current of each module calculated, the sum of power consumption in DC 5V circuit of overall system will be calculated as follows. • W5V = I5V X 5 (W)

(3) DC 24V Average Power Consumption(Power Consumption of Number of Simultaneous On Points) If calculating the sum of average consumption current of ‘External Power Supply(DC 24V) in the modules as 24V power supply output module, the sum of DC 24V circuit power consumption is as follows.(This time, PLC self supply and external supply current will be included). • W24V = I24V X 24 (W)

(4) Average Power consumption by Output Terminal Voltage Drop of Output Module(Power Consumption of Number of Simultaneous On Points) If voltage drop occurred between both output terminal in load driving such as TR and SSR output module, calculate the power consumed as a heat in drive element of module. • Wout = Iout X Vdrop X Output Point X Simultaneous On Rate (W) Iout : Output Current(Actually Used) (A) Vdrop : Voltage drop of each output module (V)

(5) Average Power consumption of Input Module(Power Consumption of Number of Simultaneous On Points) • Win = lin X E X Input Point X Simultaneous On Rate (W) Iin : Input Current(Effective Value if AC) (A) E : Input Voltage(Actually Used) (V)

(6) I/O Power consumption of Special Module Calculate the sum of power consumption occurred concerning I/O of special module. • WS = ( I5V, I+15V, I-15V, I24V, I100V, I220V ) (W)

The sum of power consumption as calculated above by block will be overall power consumption of system.

• W = WPW + W5V + W24V + Wout + Win + Ws (W)

Calculate heating amount as this overall power consumption(W) and check temperature rist in control panel. In temperature rise of control panel is calculated as follows. T = W / UA [°C] W : PLC system overall power consumption(as above calculated) A : Area in control panel [m2] U : Uniform temperature in control panel by fan • • • • • • • • • • • • • • • • • 6 Without ventilating control panel • • • • • • • • • • • • • • • • • • • • • • • 4

Trouble Type and Remedy of Output Circuit(Continued)


Abnormally Long Off Response Time of load

Excessive current in OFF [If driving stream load(Large time

constant L/R) as large current as solenoid with transistor output] t

Because current flows through diode when transistor output Off, there can be delay more than 1 second according to load.

Insert magnetic connector with small time constant and drive load with its contacts.

Broken transistor for output
