How to establish communication between a TM251MESE and a Preventa XPSMCM

Issue:
How to establish communication between a TM251MESE and a Preventa XPSMCM

Product Line:
Preventa XPSMCM, SoMachine controllers

Resolution:
I have attached a sample program using Modbus TCP, Ethernet/IP and CANOpen.
It allows to exchange data between XPSMCM and SoMachine controller via MODBUS-TCP, ETHERNET/IP or CANopen.
Inside the SoSafe project report (see attached), you will find the chapter 
Fieldbus Output bytes description with the following content:
Byte 00 - Modular Safety Controller Status
Bit 0: Modular Safety Controller on line
Bit 1: Diagnostic present
Byte 01 - CP0802 Input Bit 0: Function Block 1 Light Curtain CP0802
Byte 18 - Field bus Probe (00÷07) Bit 0: Field bus Probe 0
Byte 20 - OSSD (00÷07) Bit 0: OUTPUT1

To verify the values inside the SoMachine project, you can use the strcuture variable StatusEIP from sample project in the following way:
  • Light Curtain Input:    StatusEIP.stCM.byInputState00.0
  • Light Curtain Error:    StatusEIP.stCM.wFieldBusProbe.0
  • OSSD Output1          StatusEIP.stCM.wOutputState.0
