2.3 Slave Configuration
2.3.1 General
The following section will detail the basics of configuring the PS69-DPS module. The PROFIBUS-DP Slave module does not require a configuration tool. There are two ways to configure the Slave module. These two methods are described in the following sections.
2.3.2 GSD File
A GSD file is kind of an electronic datasheet for a particular Slave device. The GSD-File for the PS69-DPS slave named "PSFT097A.gsd" is located on the DVD supplied with the module. You have to provide this file to the configuration
tool for the network master. Refer to the Master’s user manual of how to import
GSD files.
2.3.3 Configuration by Master
The "Configuration by Master" is the easiest way to configure the Slave. The projects on the DVD contain examples which show the use of this method. During the network startup phase, the PROFIBUS Master sends the expected slave configuration over the network to compare it with the real configuration of the Slaves connected to the bus. The slave PS69-DPS automatically takes over the configuration which is sent by the master during its comparison of the configuration. This method is activated by default, since the parameter "Force User Config" in the configuration area is set to 0. The only setting required by the user is setting the Address rotary switches on the front of the module to the required network address.
Note: This is the easiest way to configure the Slave. But be aware that the master can send a new configuration to the slave at any time. This can cause inconsistency, if the new configuration does not match to the controller application. For more safety use the method "Configuration by Controller Application". With this method the slave module does not start any communication as long as the slave configuration and the master configuration don't match to each other.

2.3.4 Configuration by Controller Application
The second option to configure the Slave module is to let the controller application decide on the configuration. To do so the parameter "Force User Config" in the configuration array has to be set to 1. By setting this parameter and initialization of the other values the controller program can configure the slave. With this method the slave module will not start any network communication as long as the master and slave configuration don't match to each other. The following table shows the outline of the mapping of the configuration data image.

Profibus DP Slave Communication Module User Manual
2.3.5 Explanation of settable configuration values
Busaddress
The valid PROFIBUS address range is from 0 to 125. The module has two rotating address switches to set the network address from 0 to 99.
With the rotating switches, however, you are not able to select bus addresses above 99. If you choose 0 on the address switches, then the module will take the address parameter from the configuration data array. Now you are able to set up bus addresses above 99.
XX - Don't Care
Force User Configuration
If the parameter ForceUserConfiguration is set to 1, the slave will not start its network communication until the master and slave configurations match each other. If this value is set to 0, the slave accepts any valid configuration sent from the master.
Watchdog Timeout
The Slave module supervises its I/O exchange with the controller with a timeout. If the controller does not update the output data within this time, the Slave stops the cyclic data exchange to the master and goes into a safe state.
If the parameter ForceUserConfiguration is set to 0 then the module calculates automatically a timeout value by the RPI (Requested Packet Interval). The calculated watchdog results to 2 x the RPI (+/- 5ms). The smallest watchdog value is 15 ms. The module will round the watchdog to a multiples of 5 ms.
WATCHDOG_TIME (ms) = MAX ( 2 * RPI ; 15 ) (+/-5ms) If the parameter "ForceUserConfiguration" is set to 1 the module will take the
watchdog value from the configuration array. Make sure that the watchdog is not smaller than the RPI. The module will also round the watchdog to the next multiple of 5ms.
Number of Valid Configuration Bytes
This parameter holds the number of valid configuration bytes that define PROFIBUS Input/Output modules.

User Manual Profibus DP Slave Communication Module
Module n Type / Module n Length
The PS69-DPS PROFIBUS-DP Slave offers a flexible, modular composition of its I/O data. This means that parts of the input and output image can be viewed as single modules. The master can put the different modules from the PROFIBUS­DP Slave to different locations in its I/O area. The individual configured modules are mapped linearly in the I/O area of the Slave module. It is possible to configure up to 24 I/O modules. A module is defined by a Module Type and its Module Length:
Note: Please notice the definition of Input/Output modules and do not confuse them with the input and output area of the module in the controller memory map. PROFIBUS gives a clear definition of Inputs/Outputs. Inputs and Outputs modules are always defined from viewpoint of the PROFIBUS master. If you configure an Output module you will see this in the input area of the communication module, because the input area of the controller memory map is the output area from point of view of a PROFIBUS master. The same applies to an Input module. If you define an Input module it is mapped in the output area of the controller memory map, because the output area is the input area from viewpoint of a PROFIBUS master.
The projects on the DVD can also be used as an example for a module configuration by the controller application. You only have to set the parameter "ForceUserConfiguration" from 0 to 1 in the configuration array. In chapter "RSLOGIX SAMPLE PROGRAM" later in this manual explains the predefined configuration parameter of the sample project.

This example can be used to start a project when using a CPU 1769-L32, which supports CIP messaging. Basic PROFIBUS I/O data exchange and all messaging function examples are shown. Details on the Subroutines created and the User Defined Data Types are as follows.
MainRoutine: The MainRoutine calls all of the following routines based on
conditions such as doing a diagnostic request or to check the progress of each individual DPV1 function issued by the Master. This routine also contains a simple I/O transfer function block.
Diagnostic_Req: This subroutine Diagnostic_Req assembles a Diagnostic
Request message which will be sent to the Master. A CIP Generic Message is used to send this message.
Diagnostic_Req_Progress: This subroutine Diagnostic_Req_Progress
checks the status of the diagnostics request message sent to the Master. When the Diagnostic request is done it will increment a status counter to check how many requests have been send successfully and how many failed.
DPV1C1_Alarm_Req: This subroutine DPV1C1_Alarm_Req assembles a
DPV1 Alarm message which will be sent to the Master. A CIP Generic Messages is used to send this message.
DPV1C1_Alarm_Req_Progress: This subroutine
DPV1C1_Alarm_Req_Progress checks the status of the Alarm request message sent to the Master. When the Alarm request is done it will increment a status counter to record how many requests have been send successfully and how many have been failed.
DPV1C1_Progress: This subroutine DPV1C1_Progress checks the
inprogress bit of each service and sends the appropriate response. CIP Generic Messages are used to send the response message from the Slave to the Master.
DPV1C1_Read_Resp: This subroutine DPV1C1_Read_Resp assembles the
DPV1 Read response message. A CIP Generic Message is used to send this message. This routine will return immediately if there is still a DPV1 Read Response in progress.
DPV1C1_Read_Resp_Progress: This subroutine
DPV1C1_Read_Resp_Progress checks the status of the DPV1 Read Response sent to the Master. When the Read response request is done it will increment a status counter to record how many response requests have been sent successfully and how many failed.
DPV1C1_Write_Resp: This subroutine "DPV1C1_Write_Resp" assembles
the DPV1 Write response message. A CIP Generic Message is used to send this message. This routine will return immediately if there is still a DPV1 Write Response in progress.

When the Fault LED of the MicroLogix Controller is off, the module is not in a fault state.
If there is a problem with the expansion module, the Fault LED will be flashing red. To diagnose the error, go online with your RSLogix500 project and open up the processor status dialog box. Click the Error tab to view the fault reason.
4.2.3 SYS and COM Status LEDs
This PS69-DPS module has two bicolor status LEDs. They inform the user about the communication state of the module.
The SYS-LED shows the common system status of the card. It may flash
yellow or green.
The COM-LED displays the status of the PROFIBUS communication. It can
be solid green or off.
If the SYS-LED is solid Green and the COM-LED solid green, the card is in cyclic data exchange with the Master and the communication is running with outfault.
4.2.4 Error Sources and Reasons

5.1.4 PROFIBUS Interface
Isolated RS-485 interface per EN 50170.
Please ensure that termination resistors are available at both ends of the cable. If special PROFIBUS connectors are being used, these resistors are often found inside the connector and must be switched on. For baud rates above 1.5 MBaud use only PROFIBUS connectors, which also include additional inductance. It is not permitted to have T stubs at high baud rates.
Use only a special cable which is approved for PROFIBUS-DP. Make a solid connection from the cable shield to ground at every device and make sure that there is no potential difference between the grounds at the devices.
If the PS69 is linked with only one other device on the bus, both devices must be at the ends of the bus line. The reason is that these devices must deliver the power supply for the termination resistors. Otherwise the Master can be connected at any desired position.

5.3 PROFIBUS Functionality
5.3.1 DPV0 Services
DPV0 services in PROFIBUS refer to the cyclic data exchange mechanism between a class 1 master and a network slave. PROFIBUS-DP defines two types of masters. The class 1 master handles data communication with slaves assigned to it. A class 2 master should only be used for commissioning purposes. In a PROFIBUS telegram, class 1 masters and slaves transmit up to 244 bytes per telegram. Valid station addresses on PROFIBUS range from 0 to
125.
Fail Safe Mode
For safety reasons, the PROFIBUS master informs connected slaves of its current control status at certain intervals using a "Global Control" telegram. If the master goes to Clear Mode, the Fail Safe enabled slaves will switch to a Fail Safe state. Slaves capable of the Fail Safe state can be configured to either to hold the last state of the outputs or set its outputs to "0". Slaves that do not support the Fail Safe state set their outputs to "0".
Global Control
With the Global Control telegram, the master can send unsolicited commands like Sync/Unsync, Freeze/Unfreeze and Clear Data to a slave or a group of slaves for synchronization purposes. Group membership is defined during network start-up and can be set in the master configuration tool.
Sync and Freeze
Sync and Freeze are optional commands and slaves do not need to support them. However, they must be able to process the Global Control telegram. With a Freeze command, the master prompts a slave or a group of slaves to "freeze" their inputs to the current state. A Sync telegram causes the current output data to latch at their current state until the next Sync telegram arrives. Unfreeze and Unsync cancel each corresponding state.
Extended Device Diagnostics
Using diagnostic telegrams, the slave informs the network master of its current state in a high-priority telegram. The first 6 bytes of the diagnostic telegram are comprised of information such as its identity code ("Ident Code") or correct/incorrect configuration. The remaining bytes of this telegram are referred to as Extended Device Diagnostics and they contain information that is specific to the particular slave.
ProSoft Technology, Inc. Page 73 of 108 May 9, 2014
Reference PS69-DPS CompactLogix or MicroLogix Platform User Manual Profibus DP Slave Communication Module
Watchdog
Using the Watchdog functionality a network slave is able to monitor bus traffic in order to ensure that the network master is still active and process data sent and received are still being updated. The Watchdog time is configured in the master config tool and is transmitted from the master to the slave during the network start-up phase. If the Watchdog time out has been reached the slaves go to their Fail Safe state (if supported) or set their outputs to "0".
5.3.2 DPV1 Services
As an addition to cyclic DPV0 services, non-cyclic services called Read, Write and Alarm were added to PROFIBUS. These services are referred to as DPV1. With DPV1, it is possible to address individual modules within the slave. In addition, DPV1 services allow transferring non-time critical data to slaves who require a large amount of configuration data or slaves that have to change measurement ranges during runtime. DPV1 data exchange takes place after cyclic data exchange in a PROFIBUS network cycle.
Read Request
With a Read Request telegram, the class 1 master can read data addressed by slot and index within the data range of a slave device. This may take several DPV0 cycles. If the master discovers a timeout, it aborts both DPV1 and DPV0 communication with the slave. Then the communication to the slave has to be re­established. The master initiates the Read Request service.
Write Request
With a Write Request telegram, the class 1 master can write data addressed by slot and index into the data range of a slave device. The timeout handling is identical to the Read Request. The master initiates the Write Request service.
Alarm Indication
DPV1 Alarm handling is an addition to the Device Diagnostic function in PROFIBUS. Alarms are reported to the master as device specific diagnostic information. Therefore, the slave initiates an Alarm Indication. Other than Device Diagnostic messages, Alarms have to be acknowledged by the Master.
5.3.3 Start/Stop Communication
Start/Stop communication with one bit: With the "NRDY" (NotReady) Bit the user program can start or stop communication with the PROFIBUS-DP system. When this Bit is set from the user program, the communication between the slave and the master is stopped and will activate diagnostic request which is reported to the PROFIBUS master during runtime. The cyclic data exchange will be suspended and the module switches into a diagnostic mode and reports static diagnosis to the master. This control bit allows the user program to make a controlled start of the communication with the PROFIBUS system.

MSB := Module Status Bits
RDY (Ready) When this bit is set, the module is operational. The RDY-Bit should always be set
by the module. If this bit is not set a system error has occurred and the communication between controller and module is not possible.
RUN (Run) When the RUN-bit is set, the module is ready for communication. Otherwise an
initialization error or incorrect Parameterization occurs. COM (Communication) When this bit is set, the communication is started and the module is engaged in
cyclic data exchange with the Master. These three bits are the most important bits that the controller application can
use to monitor the communication and operating status of the module
Firmware Revision
This data field, which is part of the input image of the PROFIBUS Slave module, will contain the current firmware revision. The Minor revision indication will be in the low byte and the Major revision will be in the high byte. The Firmware Field is placed in the Input area as shown in the following table.
Example: If FwMajor = 10 and FwMinor = 1 then the firmware revision is 10.1.

Profibus DP Slave Communication Module User Manual
(*)Note: The status information "InputDataLen" and "OutputDataLen" are related to the definition of inputs and outputs from point of view of PROFIBUS. There is a clear definition of inputs and outputs by PROFIBUS. They are always defined from point of view of a PROFIBUS-Master. Do not confuse them with the input and output area of the communication module. Example: If in status 'OutputDataLen' is indicated a value of 4 Bytes, then it is related to the input area of the communication module, because the input area of the communication module are outputs from point of view of a PROFIBUS-Master. The same relation applies to the status 'InputDataLen' and the output area of the communication module.

User Manual Profibus DP Slave Communication Module
DPV1 Status Registers
The controller application program will use the DPV1 status registers as an indication that the network Master has sent an unsolicited DPV1 Read/Write request. The first will contain two bits which indicate if a read or write needs to be processed. If this register contains a non-zero value, the Slave’s user program must create an appropriate response to this request by using a CIP MSG command (shown in messaging section). The following table contains the mapping of these registers.
RWInd := DPV1 Read/Write Indication Status Bits
Note: Every DPV1 read or write request must be acknowledged by the PLC application program.
Otherwise the PROFIBUS master shuts down communication for both channels, V0 (cyclic IO data) and V1 (non-cyclic messages). This can cause unexpected lost of data between the master and the PS69-DPS slave.
Extended Status Information
Via the extended status area the Slave module is in the position to transfer 96 Byte extended status information to the controller application. The information transferred depends on the parameter "ExtStaSelect" in the "Device Command Register". This can be controlled by the application program. If the controller application selects a specific extended status, it will be acknowledged by the Slave module in the status region in "ExtStaSelect". If the slave adapter does not acknowledge this selection, the extended information is invalid. The number of bytes within the extended status area which are valid depends on the selected status. The number of valid bytes will be shown in the status area in "ExtStaLen".

The Device Command Register is transferred from the controller to the module via the output data image. The Command register always lies in the first 4 Bytes of the output region. Follows is the mapping for the Device Command Register.
MCB := Module Command Bits
NRDY := Not Ready
With this bit, the user program can start or stop communication with the PROFIBUS system. When this bit is set from the user program, the communication between the module and connected network Master is stopped. This control bit allows the user program to make a controlled start of the communication with the PROFIBUS Master.
INIT := Init
With this Bit, the user program can execute a Reset (Warm Start) of the module. This function is not implemented.
RST := Reset
The user program can use this bit to execute a Reset (Cold Start) of the module.
Attention: Using the Reset command will cause an immediate interruption in bus communication. The connection to the network Master will be closed.

PROFIBUS Input Data
The remainder of the output area is used for the PROFIBUS Input data to the sent to the network Master. The input information is transferred from the controller to the module. INPUT data from the PROFIBUS system always starts at the 4Th Byte (based on Start Index 0) in the modules output data area.
5.4.2 CIP Messaging
PROFIBUS-DP supports acyclic services through messages. These PROFIBUS­DP services are supported by the RSLogix5000 programming tool by means of CIP messages using the "MSG" instruction. The outline and usage of these commands for the PROFIBUS-DP Slave are explained with in this section.
Note: At the time of this release of the PS69-DPS module, the MicroLogix 1500 processor, as well as some CompactLogix processors, do not support CIP messaging or CIP messaging for generic Compact I/O modules. CIP messaging for PROFIBUS DPV1 services, are not yet supported with a MicroLogix System and a PS69-DPS module.
Using the MSG Instruction in RSLogix5000
CIP messages are carried out by the use of the "MSG" function block in RSLogix5000. The "MSG" function block can be found under the Input/Output Instructions tab within the RSLogix Instruction Set. The MSG instruction asynchronously reads or writes a block of data to another module on a network. The following is an example of how this instruction is assembled using the acyclic PROFIBUS-DP service DPV1 Class 1 Alarm Request command.
Step1: Create New Controller Tag
Double click on the Controller Tags tree selection under Controller CompactLogix. The Controller Tags dialog box will appear. Select the Edit Tags tab. Add a new tag called Dpv1AlarmMsg and make its Type equal to MESSAGE.
Page 84 of 108 ProSoft Technology, Inc. May 9, 2014
PS69-DPS CompactLogix or MicroLogix Platform Reference Profibus DP Slave Communication Module User Manual
Step2: Insert the "MSG" instruction
From the language element tool bar in RSLogix select the Input/Output tab and click on the "MSG" button. The instruction will be inserted into your ladder logic as shown in the figure below.
Select the ? And enter the MESSAGE type created Dpv1AlarmMsg as shown below.
Step3: Message Configuration
Select the button , which will open the Message Configuration dialog box. The configuration dialog will allow the user to fill in the appropriate information needed to execute the Dpv1AlarmMsg. The entries should be as follows.
Note: The user must create two user defined data types to send and receive the information for this command message. In this example Dpv1AlarmReq and Dpv1AlarmCnf were created to hold the command specific information.

The Path in the dialog above must point to the PS69-DPS Module. Use the Browse button to select the path.
Step 4: Add Logic to Execute MSG Instruction
With the "MSG" instruction now configured the user can add the required logic needed to execute the instruction. The example below shows the "MSG" instruction used in the example logic in PS69_DPS_messaging.ACD.

Error Code 2
Error code 2 is application specific.
Messaging Error Codes
The section includes all errors codes and conditions that can occur when using the CIP messaging commands outlined in the previous sections.
Your application should be constructed in a manner in which it catches the
two possible error cases listed below:
CIP Message instruction failed itself The requested command returns an error in its request confirmation
Only if both possibilities are without any error has the requested command been successful.
CIP Messaging General
Applicable are the generally known error codes for CIP Messages such as "Service Not Supported". In this case, the parameters of the CIP Message must be checked (Service Code, Class, Instance). All CIP error codes that are returned by the module and their cause are described in the following table.
Note: Some CIP error codes are public and can be generated also by the Controller. Make sure the error was not generated by the controller.

5.5 Constructing a Bus Cable for PROFIBUS DP
The bus cable for connecting PROFIBUS DP devices must be constructed by the user. A special PROFIBUS cable (twisted pair) is required here. This standard cable is available from various manufacturers and is a Belden part number 3079A.
If you plan to construct your own bus cable, the following part numbers are provided for your convenience.
PROFIBUS connector: Siemens part number 6ES7972-0BA40-0XA0 PROFIBUS cable: Belden part number 3079A.
To construct the cable, proceed as follows:
1 Cut the cable to the required length. 2 Prepare the cable ends as shown in the illustration (dimensions in mm):
J PVC Jacket S Braided shielding
3 Remove the PVC jacket J to the indicated length. 4 Wrap the provided copper shielding F around the shield braiding S:
J PVC jacket S Braided shielding F Copper foil shielding
Additional foil can be obtained from 3M.
5 Plug the leads of the corresponding cable(s) into the terminals as shown:
o Green leads in terminal A o Red lead in terminal B
Note: Do not tighten the corresponding screws yet.
ProSoft Technology, Inc. Page 99 of 108 May 9, 2014
Reference PS69-DPS CompactLogix or MicroLogix Platform User Manual Profibus DP Slave Communication Module
Connection terminal assignment on the PROFIBUS DP:
A Incoming cable B Outgoing cable C Connection terminals (only once (B,A)) D Cable cleat for reliving tension E Bus connector screws
6 Attach the cables with the provided cable cleat to create a robust shielded
connection and to relieve any tension as shown:
J PVC Jacket S Braided shielding with foil shielding C Cable cleat
Note: Half of the cable jacket must lie under the cable cleat!
Pay attention to the cable cleat installation instructions.
7 Fasten the individual wires of the PROFIBUS cable to the terminals 8 Close the connector housing.
Note: The shielding of both cables is connected internally with the metal housing of the
connector.
9 Complete the Central Shielding Measures (below) and grounding operations
for the shielding before you connect the cable connector to the module.
10 Plug the PROFIBUS DP connector into the module and secure it with the
screws.
