Hello Vicius; A long time ago I remember the SLC 5/04 would work with Modbus RTU. Does your SLC 5/03 provide the same interface? If so, adding a CM PTP module on the ET 200SP rack would allow serial comms between the 2 processors, one acting as master, the other as slave.Here is an application example for the ET 200SP: Master-Slave Communication via a CM PtP using the Modbus RTU Protocol https://support.industry.siemens.com/cs/ww/en/view/68202723 Hope this helps, Daniel Chartier |
