I have made a little project to communicate Unitronics and Siemens S7-1200 PLC's by MODBUS TCP:


Unitronics:
Software Visilogic 9.31

Unitronics IP: 192.168.1.200

MODBUS_COMM: Connect Sockets 0 and 2 as Slave with different ID to Siemens IP Address 192.168.1.204



Siemens:

Siemens IP: 192.168.1.204

PLC: 1214 DC/DC/DC

Software: Tia Portal V11 SP1

PLC Fw: 2.12

Modbus function: MB_CLIENT



  • Unitronics can read DB2.DBW0 from Siemens PLC
  • Unitronics can wirte MI3..MI5 to Siemens PLC

I have to do something similar but using a Yaskawa mp 2600 instead.

Why did you connect 0-2 sockets?
