Hello,
I am Japanese broken English sorry.
I am trying to create a modbus map for Modicon PLC M340. I am using UnityPro software ver11.
I am using MBP_MSTR with function code 2, and I am successful in modbus communication.
However, I selected mixed topological and state ram for extended %M register. the modbus communication with function code 2 failed.
The exception of Modbus communication is 0X02.
Just by expanding the area, the parameters of MBP_mstr have not changed.
Is there any setting missing?
