The 3UF5 SIMOCODE-DP System

There is less and less time in be-tween ordering and the start-up ofa system – however, the require-ments made on motor feeders areincreasing. A system should, forexample, be compact, intelligentand powerful. Every motor hasoptimum protection, the scope ofwiring is as small as possible andspares must not mean high storagecosts.

To meet all these requirements, thesystem designer has to have extensiveknowledge of the complete range oflow-voltage switchgear. The new com-munications-capable SIMOCODE®-DP3UF5 – Siemens Motor Protectionand Control Device - DecentralizedPeripherals – makes life easier for thesystem designer.

SIMOCODE-DP is a tried and testedsystem

Increasingly, the communications-capable SIMOCODE-DP 3UF5 motorprotection and control device is beingsuccessfully used worldwide in low-voltage switchgear systems.

It represents the intelligent linkbetween the motor feeder and theprocess control system.

The fact that this state-of-the-arttechnology is being increasingly usedreflects the requirement for increasedplant availability but at the same time,cost savings during the constructionand commissioning of a plant and itsoperation. This places a wide range ofrequirements on such an intelligentfield device.

As it is widely used in the process andothers industries, you can find it all overthe world. The system SIMOCODE-DPprotects and controls load feeders for

instance in the paper, chemical, textile,steel, oil and gas, waterwork plants,cement, petrochemical, shipbuilding,food and consumer goods industries.

There it has proved its reliability formore than five years.

Intelligent load feeders

SIMOCODE-DP also helps ensure thathigh-availability systems such as coal,gas and hydroelectric plants runaround the clock. SIMOCODE alsoprovides the communication betweenthe master level and the automationlevel by its integrated PROFIBUS-DPinterface.

In all that industries it is used for anenormous variety of applications.SIMOCODE-DP is capable to realizeseveral control functions, like direct-,reversing-, star-delta starters and toimplement user-specific controls byusing the freely assignable inputs andoutputs and the built-in truth tables,timers and counters. The existingmotor protection functions (overload,phase failure and current imbalancedetection) are supplemented bythermistor motor protection and earth-fault monitoring.

Electrical equipment such as ACmotors and transformers needprotection against excessive heating.Unbalanced current consumption,phase failure or a stalled rotor aresome of the possible causes ofoverloading.

Overload protectionSIMOCODE-DP protects the load,independent of the automation level,against overload, phase failure andcurrent imbalance. The 3UF50 basicunit can also be used as anautonomous, solid-state overload relayfor motor protection.

Finely adjustable adaptation tostart-up conditionsIt is possible to select a tripping classin six steps from CLASS 5 to CLASS30. The tripping time can be finelyadjusted to the start-up conditions –and the utilization of the motors canbe optimized.

Built-in thermistor motor protectionThermistor motor protection is used forthe thermal protection of motors. Thetemperature is measured directly atthe motor windings via a PTC or NTCthermistor detector and is evaluated bySIMOCODE-DP.␣ No additionalevaluation devices are required, thussaving space in the switchboard.

Apart from binary thermistor detectors,SIMOCODE-DP also evaluatesanalogous (KTY) thermistor detectors.KTY detectors incorporate a resistancecurve which rises linearly with thetemperature. Therefore, a warning anda tripping threshold can be set in theSIMOCODE-DP.A considerable advantage.

For motors with a thermally criticalrotor, e.g. slipring and squirrel-cagemotors with increased power, the combi-nation of thermistor-type motor protec-tion and electronically delayed overloadrelay offers full thermal protection –thermistor-type motor protection.

Earth fault monitoringalways availableThis protective function is also offeredby the SIMOCODE-DP communica-tions-capable motor protection andcontrol device. The internal earth faultdetection can be activated in additionto the thermistor evaluation.

For motors with 3-wire connection,fault currents which exceed thecurrent setting Ie (during nominaloperation) by 30% can be detectedwith the internal earth fault detection.

The SIMOCODE-DP system is alsosuitable for a precise earth faultdetection. A version is available withexternal earth fault detection. Byconnecting an external summationcurrent transformer, fault currents of0.3 A, 0.5 A and 1 A can be detectedfor both 3- and 4-wire motors.

An additional evaluation device is notrequired, and the space requirement inthe cubicle is further reduced.

Protection against stalled rotorsProtection against the stalling ofmotors during normal operation isachieved by a comparison of a settablecurrent limit.

Resettable everywhere – manual,remote and automatic resetA reset at the device is implementedwith the Test/Reset button. By con-necting a pushbutton to the inputs, viaPROFIBUS-DP or via the Test/Resetbutton at the operating module, aremote reset can be implemented. Anautomatic reset can also beconfigured.

Reduction of variants by largesetting ranges: 0.25 A – 820 AA current window from 0.25 A to820 A is covered using only six units.This reduces product selection – andsaves on spares costs.

Thermistor-Type Motor ProtectionWithout Compromise

Tolerance < ± 10%With a tolerance of less than 10%,SIMOCODE-DP has an accuratetripping curve which guarantees anoptimum utilization of motors.Long-term stability also contributes tothe high degree of accuracy.

Cost reduction by built-in currenttransformersCurrent detection is achieved via threecurrent transformers which areintegrated in the device. This means thatsavings are made three ways – i.e.space, wiring and additional devicerequirements.

Easy ‘through feed ‘connectionFeeder cables up to 100 A rating can beeasily connected to the 3UF50. Thecables are not terminated to the device,but are fed through 3 integral conduitsin the device housing – a major savingin installation time.

Protection of motors in the EExe rangeThe SIMOCODE-DP system compliesto the regulations for overloadprotection of explosion-protectedmotors of the “increased safety“ typeEExe DIN EN 50019/ DIN VDE0165,DIN VDE 0170/0171 and to the testregulations of the Federal Institute forPhysics and Technology and the testrequirements of the Federal Institutefor Physics and Technology No. 3.53-14605/96.

Cost reduction by pre-definedcontrol functions

In the SIMOCODE-DP, all necessaryinterlocking requirements for therelevant control function (e.g. withencoders the undelayed deactivationof the motor in case of an operation ofthe limit or torque switch) are imple-mented. This offers major advan-tages:

• Reducing the demands put on theuser program in the programmablecontroller, i.e. fast planning, fewerpossibilities for errors, shorterprogram cycle times

• Time-critical functions of themotor feeder are independent ofthe signal process time in theautomation level and of thecommunication system.

With the SIMOCODE-DP system, ninedifferent control functions can beimplemented:

• Overload relay• Direct starter• Reversing starter• Star-delta starter• Dahlander• Pole-changing switch• Slide valve (encoder)• Solenoid valve• SIKOSTART® 3RW22

(soft starter)

In addition, permanent or non-maintained command mode can beset. All control functions can beimplemented using the 3UF50 basicunit. If more than four inputs and fouroutputs are required, an additionaleight inputs and four outputs can befitted by using an extension module.

In addition, run time checks can be setfor the start or stop of motors and forthe slide valve control functions inbetween the limits.

Safety by operator enable andmanual/automatic switch-over

In the automatic mode, controlcommands (e.g. ON, OFF) are trans-mitted to SIMOCODE-DP via the bus.

Control commands from the switch-gear cubicle (e.g. of the operatingmodule) or from the local controlstation are only possible in thisoperating mode if the correspondingoperator enable commands have beenset.

6

Control and signalling

If the automatic level switches tomanual operation, or if local control isactivated by means of a local manual/automatic key switch, the bus controlcommands are ignored and the feedercan now be exclusively controlled viathe operating module or using the localcontrol station.

Reduction of failure times byautonomous operation

In case of system failures on thecommunication system, SIMOCODE-DP automatically switches to manualmode.

When this occurs, the load is eitherswitched OFF or the operating state ismaintained. Further control is possibleusing the manual mode.

Downtimes in case of failures in theautomation and communication levelare considerably reduced: The processcan still be safely continued locally dueto the autonomous structure of theSIMOCODE-DP.

The process can be resumed howeversurely by the self-sufficient structure ofthe system SIMOCODE-DP locally.

Self-sufficient means that allprotective relays for motor and controlfunctions are processed independentlyof the automation level in theSIMOCODE-DP.

Flexibility due to decentralizedsignal logic, delays andconditioning

The great flexibility of the SIMOCODE-DP system is especially characterizedby the integrated:

• 3 truth tables(3 inputs with 1 output each)

• 1 truth table(5 inputs with 2 outputs)

• 2 timers(0.5 s...60 min; output behaviour:ON delay, OFF delay, fleetingNO contact)

• 2 counters (0...65535)

• 4 elements of signal processing– Inverted level without memory– Rising edge with memory– Falling edge with memory

• Signal conditioning– 3 flashing modules– 3 flickering modules

• 2 elements of non-resettingon-voltage failure

The inputs and outputs of the systemcan be assigned to predefined controlfunctions as well as to the truth tables,timers and counters. Thus, a flexibleuse of the predefined control functionsis possible.

The make/break contact behaviour ofthe outputs is set by the signalprocessing modules.

Selective start of the system

After a mains failure, the motor feederscan be restarted using time-grading.This makes a fast and selective start ofthe system possible.

Always informed as to the currentoperating state

SIMOCODE-DP continuously informsthe process engineer about the currentoperating state:

• actual phase current in %• ON/OFF• Anti-clockwise, clockwise LEFT/

RIGHT• Fast, slow• Slide open, closed, moving• Warning• Fault

Reduction of failures by thesignalling of critical operatingstates

The settable current limits inform theprocess engineer about critical statesin the system. For example, a currentwhich is below the lower current limitsetting could mean a broken conveyorbelt for example. The overloading of amixing machine for example can bequickly detected by the display of‘upper current limit exceeded.’ To avoidan overload trip of the machine, theprocess engineer can take precisesteps to change the working process,such as reducing the amount ofmaterial in the mixer.

Extensive Diagnostics

Display of other critical operatingstates:

• Current imbalance• Overload warning/trip• Thermistor motor protection

warning/trip• Earth fault warning/trip• Locked rotor protection• Warning/trip upper/lower current

limit response

Reduction of maintenance times

Maintenance intervals can beincreased, as all statistical data relatingto the condition of a particular feeder istransmitted from the SIMOCODE-DP tothe PLC. SIMOCODE-DP registers thenumber of starts and the number ofoverload trips, counts the operatinghours and calculates the current in %of the last trip. All data is stored in anon-volatile memory in SIMOCODE-DP.

Analog current display

For display of analog current valuethrough a display device on the paneldoor; the SIMOCODE-DP system isprovided with an external currenttransformer (range 0.25 A–820 A/1A).With this it is also possible for thesystem selector to inform about theactual current flowing in the motorfeeder.

Self-monitoring

The correct function of theSIMOCODE-DP processor ispermanently monitored. If a faultoccurs, SIMOCODE-DP switches theload into the safe condition which waspreviously parameterized (OFF or theoperating status is maintained -monostable or bistable behaviour).

Also testable ‘in action’

This function gives SIMOCODE-DPadditional safety and better monitoringfeatures.

The operation of SIMOCODE-DP canbe checked during running – withoutswitching off of the motor. This savestime and avoids unnecessaryinterruptions of the operation.

Display and diagnoses with Win-SIMOCODE-DP software

SIMOCODE-DP offers a large amountof operational and statistical data onthe feeder, which is available to theuser for visualization and diagnosticpurposes.

This data can be accessed:

• directly at the switchboard via theLED display of the hand-held unitplugged into the basic unit oroperator panel, or via a PC withWin-SIMOCODE-DP/Smart.

• via PROFIBUS-DP. The data can beread by the user program and it canbe transferred to a correspondingoperator communication andmonitoring system. Thus, the variousoperational and statistical informationcan be displayed in the control room.

• over PROFIBUS-DPV1 with acommunications processor whichwere in the PC/PU and the softwareWin-SIMOCODE-DP/Professional.

8

PROFIBUS-DP (Process Fieldbus -Decentralized Peripherals) provideshigh-performance communicationbetween the SIMOCODE-DP and theautomation level. Control commands,operational data, statistical data andparameter data are transmitted via thetwo-wire bus cable. There is also thepossibility to use optical link modulesso that the data transmission would beeffected via plastic or glass fibre opticcables.

Here, the communications processor(CP/IM) plugged into the program-mable logic controller (PLC) provides themanagement of the SIMOCODE-DP

Communication –PROFIBUS-DPV1

The PROFIBUS-DP standard has beenextended by acyclic reading and writingof data and is named PROFIBUS-DPV1.Acyclic reading and writing means forSIMOCODE-DP that from a centralworkstation over PROFIBUS-DPV1with a PC or PU fitted with communi-cations processor and the softwareWin-SIMOCODE-DP/Professional allcontrol, diagnosis, test and parameterdata can be read and written. ThePROFIBUS-DPV1 is a secondaryprotocol for the PROFIBUS-DP, and itdoes notrequire additional lines orinterfaces.

SIMOCODE-DP is listed asa full compatible and certi-fied PROFIBUS device. Thisensures that the communi-cations-capable devise fullysupports the EN 50170PROFIBUS standard.

Siemens together withmore than 1,100 othermembers around the worldmakes PROFIBUS Inter-national (PI) the world’slargest organization forindustrial communication.The local representationwith regional PROFIBUSAssociations (RPA) in 23countries ensures world-wide PROFIBUS support.

The communication processors

SIMOCODE-DP can work with anystandard DP master which is able toread GSD files and which is capableof processing the following amountsof data:

• Control data 1 or 4 byte cyclic fromthe DP master to SIMOCODE-DP

• Signalling data 1/4/12 byte cyclicfrom SIMOCODE-DP to the DPmaster

• Diagnosis data 20 byte acyclic fromSIMOCODE-DP to the DP master

• Parameter data 213 byte

For acyclic reading and writing ofdata, the communication processormust operate with the standardextension PROFIBUS-DPV1.

Bus system expandable

If no bus system is applicable at thetoday‘s point in time, this then can beeasily re-tooled later. That‘s becauseSIMOCODE-DP processes all pro-tective relays for motor and controlfunctions independently of theautomation level.

Of course, SIMOCODE-DP is alsogenerally applicable as self-sufficientprotective relay for motor andcontroller without PROFIBUS-DP.

Simple Start-Up

Integrating many slaves using onlyone software

The integration of SIMOCODE-DP as aDP slave within SIMATIC S7 is as easyas possible. Configuration andparameterization of the wholehardware including PROFIBUS-DPnetwork and all PROFIBUS-DP slavesis handled by the SIMATIC Manager.No matter whether you work withcentral or decentral periphery devices,whether you have only SIMOCODE-DPor also other DP slaves – everything ishandled by one software.

SIMOCODE-DP – onlineparameterization

Now the user is able to parameterizehis SIMOCODE-DP “online“ from acentral location by using thePROFIBUS-DP.

So, what is meant by “online“?Up to now it was only possible totransmit device parameters from theDP master to the DP slave during thesystem start-up. From now on it´s alsopossible to read and write thoseafterwards. Access is now available not

Possibilities of parameterization

only for the cyclic transmitted inputand output data but also to a numberof SIMOCODE-DP data setsadditionally to the device parameters.

This means that based on a centraldevelopment and diagnosticworkstation with our new Win-SIMOCODE-DP/Professional softwareyou are now able to parameterize,observe, control and test via thePROFIBUS-DP.

This workstation should be equippedwith a personal computer (PC) or aprogramming unit (PU) having aninterface for PROFIBUS-DP (e.g.CP5611, CP5613). If a Siemens PU isused, the required PROFIBUS-DPinterface is already integrated.

Reduced commissioning time

It’s no longer required to run fromswitchroom to switchroom toparameterize motor feeders. Based ona central workstation, all of thePROFIBUS-DP-connectedSIMOCODE-DPs can be parameterizedafter the bus parameter has once beenset correctly.

Increased system availability

In the past, changing of parametersoften meant an interruption of programprocessing in the programmable logiccontroller (PLC) – meaning a full stopof the whole system.

By using WinSIMOCODE-DP/Professional,you can transmit SIMOCODE-DPparameters directly via PROFIBUS-DPto each single unit – without stoppingprogram processing in the PLC.

Totally Integrated in SIMATIC S7

Interconnectivity from SIMOCODE-DP to a PROFIBUS-DP network

Parameterization with Win-SIMOCODE-DP/Professional

”Totally Integrated” in SIMATIC S7 –with OM SIMOCODE-DP

Win-SIMOCODE-DP/Professional is“totally integrated“ in SIMATIC S7.Is your application focusing on a cen-tral data management for programsand parameters, the object manager(OM SIMOCODE-DP) integratesSIMOCODE-DP/Professional intoSTEP7 HW-Config – allowing you toparameterize your SIMOCODE-DPfrom there.

Therefore, you have got the uniquepossibility of parameterizing all unitswith the same softwareWin-SIMOCODE-DP/Professionalregardless whether the parameters arestored in a central PLC or are loadedsingly into each device.

A plus for commissioning

Another advantage of the SIMOCODE-DPsystem is that a motor feeder can betested during the commissioning stagewith the Win-SIMOCODE-DP/Professionalsoftware. This means, there lies apossibility that one can switch on and offfrom a central workstation and also setthe testbits and enquire about the devicestate.

Price Advantage with SIMOCODE-DP

Figure 1 shows the configuration of atypical communications-capable motorfeeder with overload relay, thermistormotor protection device, earth faultdetection, current value transmissionvia A/D converters and a decentralizedperipheral system for the busconnection.

Figure 2 and Figure 3 show the motorbranch of the future.

Reduced number of productscover the entire range

For the complete control andmonitoring including connection to thePROFIBUS-DP, only SIMOCODE-DP isrequired. This means that no additionaloverload relays, thermistor evaluationdevices etc. need to be installed.

Reduction of the scope of wiringbetween field and control level

Communication between the fieldlevel and the higher automation level(PLC or process control system DCS)

is normally implemented via couplingdevices and point-to-point connectionsto input and output modules of thePLC or DCS. With the application ofSIMOCODE-DP, the scope of wiring isreduced to a minimum – a two-wirePROFIBUS-DP cable for up to 100motor feeders; coupling devices andinput/output modules, cable gallery arenot required.

Reduction in wiring costs inthe field level

In the case of the reverser starter(figure 3), no electrical interlocking isrequired, and no time-delay relay whichprevents a direct switch-over fromclockwise to anti-clockwise rotation isnecessary. Everything is implementedwith SIMOCODE-DP.␣ The only thingrequired is to set the desired switch-over delay time.

Connection between basic unit,extension module or operatingmodule.

Bus terminal/bus terminationmodules

If the PROFIBUS-DP is connected tothe basic unit, the standard 9-pole Sub-D plugs with built-in bus terminatingresistor can be used. Especially for theapplication of SIMOCODE-DP in MotorControl Centers (MCC drawout unitdesign) there is a bus terminationmodule with built-in power supply. Thisguarantees that even the last unit inthe bus can be removed without anyimpairment of the data flow.

Operating manual

A manual for the SIMOCODE-DPsystem is available which describeseach detail of the functionality ofSIMOCODE-DP. It is intended as an aidfor project planning and system start-up and it features a comprehensivedescription of the PROFIBUS-DPcommunications interface and projectexamples.

16

As well as the communications-capable 3WN6 circuit-breakers andAS-Interface modules, SIMOCODE-DPnow provides another communicationsmodule for low-voltage switchgear.

SIMOCODE-DP can be used inSIVACON® for the control of allfeeders in both fixed and drawoutdesign.

High availability – no problem withSIVACON drawout design

SIVACON drawout design enables thesystem operator to adapt quickly tochanging system requirements.

With the integration of SIMOCODE-DPdirectly into the drawout units, a clearconnection to the feeder and thecorresponding SIMOCODE-DP isreached. A replacement of drawoutunits is possible without interruptionof the bus connection.

Technical configuration of theSIVACON switchgear withSIMOCODE-DP

The 3UF52 operating module isalways accessible from the frontand is situated in the front panelof the relevant drawout unit.

The 3UF50 basic unit with the inte-grated current transformers is builtinto the inside of the drawout units.

Each feeder can be adjusted and con-trolled autonomously at the switch-board by connecting the PC with theWin-SIMOCODE-DP software to theoperating module integrated into thefront panel. In addition, all operation,diagnostic and statistical data deter-mined by SIMOCODE-DP can be read.
