I want to make PUT GET communication between a plc and two different plc.But one plc is communicating with one plc, when I want to communicate with two plcs at the same time, communication cannot be established and it is constantly busy.

- PLCs are not in the same project,

- I defined a different connection ID for each connection, ( 105, 106 ),

- Each plc s71500 series,

As far as I know and have read, it is necessary to ensure simultaneous communication,

What do you think I should check?
