Hello,

I have the same problem.

I have an S7-1200 1214C CPU (6ES7214-1HG31-0XB0) with firmware V3.0

I configured MB_CLIENT_DB like attached file.

When I launch the project, the Modbus Slave software see the comunication and show the correct function code 03 (read Holding register) but the value of ModbusData_DB (MB_DATA_PTR) doesn't change

Someone can help me?

Thanks

Split from MB_CLIENT v3.1 doesn't work.
