Overview 1 1.1 Product overview

The PSB modules are conceived for an EMS that is equipped with the EMS400S plant controller. Operating in combination with an S7-1200 CPU, the PSB modules act as a plant segment controller and carrier controller.

Communication in the EMS is handled by the "PSB-S modules" and "PSB-C modules". These modules set up the connection for communication between the stationary and mobile sections of the unit. The PSB-S module is assigned to the stationary system section. The PSB-C module is part of the carrier controller and, therefore, the mobile part of the EMS.

The PSB modules are technology modules of the SIMATIC S7-1200 product series.

A PSB-S module supports communication with the EMS carriers. Up to three independent plant segments of an EMS can be connected to one PSB-S module. The PSB-S module is designed for communication with up to 30 PSB-C modules per plant segment.

The PSB-S modules in combination with a CPU form the EMS400S plant segment controller. The EMS400S carrier controller consists of a CPU and a PSB-C module.

Overview 1.2 System limits


1.2 System limits The following applies to PSB-S and PSB-C modules:

● PSB-S module – PSB-C module communication

The communication between the plant segment controller and carrier controller and thus between PSB-S and PSB-C module is based on the following parameters.

Parameter Value Comment PSB-S module Maximum 30 PSB-C modules

per RAIL Applies to each connected segment. Up to 3 can be connected.

● Power supply

The value refers to the 48VDC input on the PSB-S module. Observe the specifications in the section "PSB-S module (Page 56)".

The following condition must be met for the load of each connected LOGO!Power power supply module to maintain the system limits:

4 A ≥ 0.22 A × n + 0.013 A × m 1 n … number of PSB-S modules m … number of PSB-C modules

1 The value 4 A refers to the maximum current-carrying capacity of a LOGO!Power power supply module.

Information can be found in the section "Interfaces of the PSB-S module (Page 62)".

Examples:

– 4 A ≥ 0.22 A × 5 PSB-S modules + 0.013 A × 223 PSB-C modules

When you use 5 PSB-S modules, up to 223 PSB-C modules and therefore up to 223 EMS carriers can be used.

– 4 A ≥ 0.22 A × 10 PSB-S modules + 0.013 A × 138 PSB-C modules

When you use 10 PSB-S modules, up to 138 PSB-C modules and therefore up to 138 EMS carriers can be used.

1.3 Scope of delivery The scope of delivery includes:

● 1 × PSB-S module, order number 6ES7228-1RC52-0AA0

or

● 1 × PSB-C module, order number 6ES7228-1RC51-0AA0

Data processing plant segment controller – carrier controller 6

Duration of processing The time it takes to process the data is made up of the duration of internal processing on the controller and duration of the transmission of this data on the corresponding communication connections.

The following figure shows the flow of data that is not to be acknowledged.

The transmission time is doubled for data to be acknowledge. Moreover, the time it takes for processing in opposite direction must be added, i.e. from the carrier controller to the plant segment controller.

Note

The length of a data subframe can be determined via by the START signal with the diagnostics unit.

Data processing plant segment controller – carrier controller


OB1 cycle time When creating the EMS project, observe the following information to ensure the proper response of the system:

The longer the OB1 cycle is, the higher the probability that the time available for the data subframe will be exceeded. If the time slice is exceeded, the PIO of the segment and carrier controllers will be transmitted in the next data subframe. This procedure delays the reaction time of the controller by the time it takes to transmit a data subframe.

Recommendation: The maximum OB1 cycle time of 10 ms should not be exceeded with a minimum SYNC time of 250 ms.

Data processing Keep in mind that the requirements on the synchronization signal must be observed during data transmission. See section "PSB-S module (Page 56)".

If the time slice configured for the data subframe is exceeded as a result of data processing, transmission of the completed data subframe is delayed until the next data subframe. Transmission is delayed by one synchronization clock cycle, depending on the time configured. For example, the delay would amount to 250 ms at a time of tSYNC = 250 ms for the synchronization signal.


Creating and transmitting projects 7 7.1 Creating a project in the TIA Portal

You need several projects to meet the technical requirements for operation of an EMS with EMS400S carrier controller.

● Control level 1 – project for the EMS controller

This project is optional. However, the following projects are indispensable for communication between the two controllers.

● Control level 2 – project for the plant segment controller

● Control level 3 – project for the EMS400S carrier controller

For more information, refer to the "EMS400S Plant control system for EMS plants" system manual.

Configuration software The following configuration software is approved:

● The plant segment and EMS400S carrier controllers can only be configured on the TIA Portal.

Approved version of the configuration software:

SIMATIC TIA Portal V12 SP1 or higher

For more information, refer to the corresponding Online Help.

An example is available for download from the following Internet URL:


Requirement ● The configuration software is installed on the configuration computer

● The add-on "Siemens TIA Portal Vxx EHB AddOn - S7-1200 PSB" is installed

"Vxx" stands for the installed version of the TIA Portal software.

● The TIA Portal is open.

You can find the EMS400S components in the TIA Portal hardware catalog as of V13 at:

– Catalog > Technology modules > Power Signal Booster Segment

– Catalog > Technology modules > Power Signal Booster Carrier


Creating and transmitting projects 7.1 Creating a project in the TIA Portal


Procedure 1. Create a project in the TIA Portal.

2. Configure a CPU for a plant segment controller in the "Devices" editor.

3. Insert the required number of PSB-S modules from the hardware catalog.

The following figure shows the resultant modification of the device view. This view is valid as of TIA Portal V13.

① CPU ② PSB-S module in the device view ③ PSB-S module in the hardware catalog

4. Configure a CPU for a carrier controller in the "Devices" editor.

Note

Only the CPUs operated on DC voltage are approved for the PSB-C module. Project compilation will be aborted if an CPU that is operated on AC voltage is used for the link.

Creating and transmitting projects 7.1 Creating a project in the TIA Portal


5. Insert a PSB-C module from the hardware catalog.

The following figure shows the resultant modification of the device view. This view is valid as of TIA Portal V13.

① CPU ② PSB-C module in the device view ③ PSB-C module in the hardware catalog

6. Configure additional devices in accordance with the EMS requirements.

7. Save the project.

Creating and transmitting projects 7.2 Transferring the project


7.2 Transferring the project It is prerequisite for operation of the plant segment or carrier control to provide a project in the corresponding CPU. The following routes are available for transmission of a project to the segment controller or carrier controller:

● PROFINET

The PROFINET interface is provided for data transmission from a stationary input device.

● Memory card

The memory card slot on the CPU.

The transmission routes are specified in the information system of the TIA Portal.

Note

The ERR RAIL LEDs of the PSB-S modules may flash asynchronously system-dependent during project download to a segment controller.

The data is transmitted separately to each PSB-S module via the SM bus. This operation results in runtime differences. Time offset of the flashing always occurs when the CPU is in STOP state.

7.3 Commissioning a project For information on commissioning of the project for control level 3 and accordingly of the PSB-C modules, refer to the "EMS400S plant control system for EMS plants" system manual.


Diagnostics options for PSB modules 8

The following diagnostics options are available for the PSB modules:

● Diagnostics in STEP 7

You can run the diagnostics online in the network and device view, and with the help of the diagnostic buffer of the CPU.

● Alarm messages in the user program

● Creating user-specific Web pages for the S7-1200 Web server

● Diagnostics by means of EMS400S function blocks

● LED display on the PSB module

● Diagnostics using the EMS400S diagnostics unit

The diagnostics options are described in the following sections.

8.1 Diagnostics in STEP 7 You may also view the diagnostics information of configured PSB modules in STEP 7.

The information of the PSB modules is symbolized in the device view. The status is also displayed in the "Local modules" area of the project navigation by an icon on the right side of the device. For information on the meaning of status icons, refer to the corresponding tooltip.

Requirement ● The respective controller was selected in the "Project navigation" window

● An online connection was set up between STEP 7 and the selected controller

Procedure

Overview of the diagnostics information

The structure of the "Project navigation" provides a fast overview of the plant status, as diagnostics information is distributed hierarchically to the higher-level components. For example, this means that the icon indicates an "Error in sublevel component" at the controller if one or several PSB modules report an error.

1. Select the device view.

The device view displays a status icon for each PSB module. The icon color signals the following states:

Red Error pending Green No error at the PSB module

Diagnostics options for PSB modules 8.2 Messages and errors


Diagnostics information details

1. You can obtain detailed information by selecting "Project navigation" Controller > Online & Diagnostics in the window.

2. Select "Work area" Diagnostics > Diagnostic buffer in the window.

The "Diagnostic buffer" window displays all events, including their details.

For more information, refer to:

"S7-1200 Automation System" system manual (http://support.automation.siemens.com/WW/view/de/36932465/0/en)

8.2 Messages and errors The PSB module transmits a diagnostics interrupt request to the PU in the following situations:

● The PSB module has detected a problem – incoming event

● The problem was rectified or is no longer pending – outgoing event

● An event is pending and another event is detected.

If an event is pending and another event is detected, the first event is acknowledged as "outgoing event", while the new event is entered as "incoming event".

8.2.1 Diagnostics error OB 82 If an OB 82 exists, the operating system responds to incoming or outgoing events by calling OB 82. The S7-1200 CPU will then interrupt the cyclic user program and execute OB 82. You are provided diagnostics information in the local data of OB 82. This information may include:

● Which module has triggered the interrupt?

● Which type of error has occurred?

On completion of OB 82, the S7-1200 CPU resumes the cyclic program at the interrupt position.

For more information about OB 82, refer to:

● EMS400S product documentation (http://support.automation.siemens.com/WW/view/en/68156412/133300), "EMS400S Function Blocks" Application Manual

● "S7-1200 Automation System" system manual (http://support.automation.siemens.com/WW/view/de/36932465/0/en)

Note

Diagnostics information can only be read from the diagnostic buffer if OB 82 is missing.






8.2.2 List of diagnostic entries The following section lists the events that trigger an entry in the diagnostic buffer of a PSB module.

● Single error in the STEP-7 diagnostic buffer

Diagnostic entry Description Low voltage Plant segment controller: 30 V, relative to 48 V

See section "Plant segment controller (Page 29)". Overvoltage Plant segment controller: 52.5 V, relative to 48 V

See section "Plant segment controller (Page 29)". Overload This error may be generated in the plant segment controller. The plant

segment controller drives too many carrier controllers in the three connected plant segments. "Overload" is also triggered in the following scenarios: • Short-circuit between RAIL A and RAIL B in a plant segment • Polarity reversal of RAIL A and RAIL B in a plant segment

This only applies if an EMS carrier is currently present in the respective plant segment. The carrier controller is properly wired.

See section "Plant segment controller (Page 29)". Overtemperature The module is operating outside the temperature specification.

If the temperature in the PSB-S module increases only minimally, the "Overload" message generated.

Process interrupt lost/sampling error

• Plant segment controller: Synchronization signal missing Check the data connection for the synchronization signal, starting at the signal source.

• Carrier controller: Synchronization signal missing Check whether a synchronization signal is set at the PSB-S module. Check the RAIL cable connections.

Invalid/inconsistent firmware, FW update required

The PSB module and the existing firmware are incompatible. Update the PSB module firmware. Carrier controller: This message also concerns the firmware of the display unit in case a display unit is connected.



● Group error in the STEP-7 diagnostic buffer

Diagnostic entry Description Error Applies to the plant segment controller:

General device error on RAIL 1 to 3 Error in carrier controller. Such events may, for example, include an interruption of the power supply. It is not necessary to examine the EMS carrier.

Unknown error 000B • Plant segment controller

Check whether the 48 V input voltage is present. If yes, the PBS-S module has failed. Return the PSB-S module to Siemens for repairs.

• Carrier controller Check whether the 24 V input voltage is present. If yes, the PBS-C module has failed. Return the PSB-C module to Siemens for repairs.

Unknown error 000C Applies only to the carrier controller: Configuration error. The 10-bit range of the analog output is exceeded. Check the corresponding STEP 7 project.

Note

The "Error" event is displayed as incoming and then immediately as outgoing at the startup of a PSB-S module. This system-related event is triggered during startup and does not represent an error.



8.2.3 Power supply fault. The following table contains a selection of possible errors. You can see how these errors are displayed and what you have to do to rectify the error.

Error Diagnostics event 48 V input voltage is missing permanently

A combination of the following diagnostics events is triggered: • Error • Unknown error 000B

Input voltage 48 V missing max. 250 ms or short-term interruption of the synchronization signal at the PSB-C module

The following diagnostics event is triggered: • Error

Polarity reversal of the 48 V input voltage

A combination of the following diagnostics events is triggered: • Process interrupt lost/sampling error • Unknown error 000B The bridging of two PSB-S modules may result in the communication failure of several PSB-S modules.

Input SYNC is not connected, or the synchronization signal is not generated

• The SYNC LED is inactive • The ERR RAIL LEDs do not provide optical feedback • The "Process interrupt lost/sampling error" diagnostics event is

displayed in STEP 7

Input SYNC it is connected, the frequency of the synchronization signal is too high

• The SYNC LED is active • The "Process interrupt lost/sampling error" diagnostics event is

displayed in STEP 7 Reduce the clock frequency for the synchronization signal.

Short-circuit on RAIL Short-circuit at RAIL A and RAIL B of a plant segment.

• Plant segment controller

The following diagnostic events are triggered: – ERR RAIL LEDs 1 to 3 are active – The presence and validation bit in the PII are set to zero

• Carrier controller

The following diagnostic events are triggered: – SYNC LED is inactive – ERR RAIL LED is active – Process interrupt lost/sampling error

The data corresponds to the last data read. Polarity reversal on RAIL Polarity reversal at RAIL A and RAIL B of a plant segment.

Error on overload and short-circuit on RAIL While the polarity is reversed on rail RAIL, only the ERR RAIL LEDs of the PSB-S module at the plant segments where polarity is not reversed are lit. The ERR RAIL LED of the plant segment at which polarity is reversed is switched off.

Glossary

ACK bit Acknowledgment bit that is mapped to the PII and PIO of the plant segment controller and carrier controller.

The ACK bit is used to toggle the data flow on the → RAIL between the data to be acknowledged and data that is not acknowledged in the process image.

Bridge bit The bridge bit is used by EMS carriers to reliably recognize the segment bridges. To accomplish this, the parity bit configured in the data frame is formed in → 2 bridge bits as 01 or 10. The bridge bits 11 mean there is a segment bridge. The bridge bit is transferred via → RAIL.

Broadcast The term broadcast denotes the transmission of data packets from a source station to all other nodes on the data network.

Transmission to an → EMS with the carrier controller means the broadcast of dispatch data from one → plant segment controller to all → EMS carriers of a → plant segment.

C data Data that is sent the interface from the → PSB-C module over the → RAIL interface.

Carrier controller The control component of the EMS400S carrier controller consisting of a CPU and a → PSB-C module. The carrier controller controls the → EMS carrier.

Contact conductor Electrical part of the EMS rail. The EMS rail is equipped with 6 contact conductors. The contact conductors are used to supply power to the → EMS carrier and the data communication. The two contact conductors for data communication are called → RAIL.

Control data Data that controls → user data traffic between the PSB modules. The control data are resent with each → data subframe.

Glossary


Current collector carrier 6 current collectors are mounted to the current collector carrier. The current collectors move inside the → contact conductors and maintain electrical contact. This system ensures uninterrupted power supply and data exchange while the → EMS carrier is moving.

Data subframe The data subframe relates to communication between the PSB-S and PSB-C modules. The data subframe encompasses the START and PRES signals, the → user data, the → control data, the checksum and the time for preparation of the user data.

Device error, general The general device error is a function failure of the → carrier controller that triggers the diagnostic entry → error.

EMS Automatically controlled electric monorail system for internal transport – e.g. a conveyor system.

EMS carrier Mobile component of the → EMS and carrier of the → carrier controller.

EMS rail Component of the carrying structure of the EMS. As carrier rail it serves to suspend and move the → EMS carriers. The → contact conductors installed on the EMS rail provide the means for the power supply and communication. The contact conductors are made of an insulated standard U profile that is contacted on its inside by the current collectors.

The combination of UMC rails and bypass sections forms the rail system of the → EMS.

EMS400S Siemens product name and type of → plant controller with a → carrier controller – particularly for → EMS.

Enable bit The enable bit is mapped to the PIQ of the plant segment/carrier controller and set by the function blocks.

The enable bit enables data transmission to the → RAIL. In the → PSB-S module, the enable signal applies simultaneously to all of its three connected → plant segments.

Glossary


Error The "error" event in the diagnostic buffer of the TIA Portal is equivalent to the "general device error". Such an error is reported, for example, if the → EMS carrier is off power, or if the CPU of the carrier controller is in STOP state. This means that the cause of a general device error is found in the carrier controller, i.e. in its CPU or corresponding → PSB-C module. The carrier controller reports the "error" and the plant segment controller maps it.

Infeed The term infeed denotes the supply of a corresponding medium to a network. In this document, this refers to the power input to a → contact conductor rail of the → EMS rail.

Parity bit The project engineer create a configuration once before commissioning the project to determine the → plant segments of parity 0 and the plant segments of parity 1 that are assigned. Adjacent plant segments require different parities. See also → Bridge bit. Bridge bits 01 are derived from parity 0 and bridge bits 10 are derived from parity 1.

PELV Protective extra-low voltage in accordance with the PELV standard for the protection against electrical shock. PELV is used whenever it is necessary for operational reasons to ground active conductor rails of the extra-low voltage, or equipment bodies.

Presence bit The presence bit is mapped to the PII of the plant segment controller.

The → carrier controller reports its presence by setting the PRES signal as soon as it detects the START signal on → RAIL. The presence bit indicates the PRES signal in the → plant segment controller.

PSB-C module Technology module that is linked to a CPU. The PSB-C module is part of the → carrier controller.

PSB-S module Technology module that is linked to a CPU. The PSB-C module is part of the → plant segment controller.

RAIL RAIL is derived from the English term Railing; in this document it relates to the → EMS rail. In an EMS, the term RAIL denotes the terminals on the → PSB-S and → PSB-C modules, as well as to the → RAIL contact conductor of the → EMS rail and, therefore, to the data connection between the PSB-S and PSB-C modules.

Glossary


Rail intersection The rail intersection separates the → RAIL contact conductors electrically at the → plant segment transition.

Rail system The total of all → EMS rails of an → EMS.

S data Data that is sent the interface from the → PSB-S module over the → RAIL interface. The S data sent can be both acknowledged and unacknowledged data.

SELV Safety extra-low voltage in accordance with the SELV standard for the protection against electrical shock.

Standby bit The standby bit is mapped to the PII of the carrier controller.

The standby bit is set in the → EMS carrier if the → enable bit is not set in the plant segment controller; the corresponding communication link is free of error in this case. However, no → user data is transmitted.

Synchronization signal The synchronization signal serves to ensure synchronous data transmission from all → plant segment controllers to the → EMS carriers. The synchronization signal is generated by a plant segment controller and transmitted simultaneously to all → plant segment controllers of the → EMS.

User data User data are data and messages transferred between a → plant segment controller and a → carrier controller. User data can be acknowledged or unacknowledged data. User data are a subset of → S and C data. User data → can be sent with each → data subframe.

Validation bit The validation bit is mapped to the PII and PIO of the plant segment controller and carrier controller.

The validation bit identifies valid transmitted and received data.
