Hi all,
I've only worked on Profinet once before to talk between a few S7-300 PLCs.
I managed to get the system communicating by using the "GET" and "PUT" commands. Basically I put a datablock on the 'source' PLC and another datablock with the same structure on the 'destination' PLC and then just run "GET" / "PUT" every second or so to transfer information between the PLCs.
I wondered if there was a better way of doing things?
Or is that the only way of transferring data?
Is there not anything like a DP Coupler where you can set up addresses that will be transferred between PLCs?
Thanks for your help
