I need to use 2 CP341 with Modbus RTU Dongle and communication block in the same CPU rack. (Customer ask to get redundan network connectivity...dont ask me why....)
I succeeded making 1 working well at the begining just before having to send parts for panel construction and now i'm not sure which part i should double in my cpu program...
Both CP341 (6es7 341 1ch02-0ae0 ) with dongles (6ES7 870 1AB01 0ya1) Are installed on a remote i/o rack using IM153 Profibus
Doubling only the call for Modbus blocks in OB1 with respective module adress seem too easy to me but i don't have the hardware installed yet to test it...
Any idea or anyone ever do that succesfully ?
