Hello guys,
I have problems with the Porfibus communication to my regulator Siemens Sipart DR 21and my PLC rockwell 1756-L161.
So, for the communication between the 2 devices i have on the plc a card MVI56-PDPMV1 made by prosoft, and i have a card 6DR2803-8P made by Siemens on my regulator.
The concern is that once the communication is established, I don't know how to send information from my regulator to my PLC, nothing is specified in the documentation and no approach or software is recommended.
I am in a stalemate.
If anyone among you has already done a transfer of data via Porfibus to a regulator of this type I would be grateful for his help.
Thank you all and have a nice day.
