PLC Connect: One object having signals in two different devices
I can't find a suitable workaround that allows me to have one object with signals in two different devices (PLCs), working with PLC Connect in Modbus TCP. Maybe using Calculations is the solution but in fact, it is not working properly in some situations.
Any help would be appreciated.

You create you object types in the object type structure,
Then you create instances of this object in Control Structure.
Then in Control Structure create PLC Connect generic Control Network, create 2 controllers and add the objects under the PLC.
Then you don't get into the situation where one object need to read from two PLCs.

Yes. Doing this is creating separate communication channels with the two PLCs. Object types are common, whereas instances are unique and can behave independently.
