Hello Daniel,

I need your help to connect three s71200 plc in which master PLC S71215C with CM1243-5 and remaining two S1214c with CM1242-5.

I want to know the steps of communication, data tranfer block and how can we transfer status from two 1214c filed plc to master and control status from master 1215c plc to filed.

Thanks!

Hello zeljko;
Have a look at the following FAQ, describing specialized functions for Profinet communications:

How do you program the TSEND_C and TRCV_C instructions for open user communication over the integrated PROFINET interface of the S7-1200 CPU?

There is a sample program attached.
Hope this helps,
Daniel Chartier
