Hi.
I'm trying to implement Modbus RTU Slave Device (PLC as Slave) only with libraries (no modbus devices added in my device tree)
It seems i could use "Modbus Server" FB in IoDrvModbusSerialSlave Library.
However, there are no variables for setting "start addresses of coils, discrete inputs, holding registers and Input Registers".
1) is it correct to use Modbus Server FB to implement Modbus RTU Slave?
2) where do i set "start addresses of coils, discrete inputs, holding registers and Input Registers"?
