Hi .Sir

I need to help your technical support about S7MODM3 FUNCTION BLOCK.

My project need to communicate using MODBUS RTU with S400H & CP341.

The information that should be made are as follows.

Slave ID : 1(1 device)

Function Code : 4(Input resistor)

Address : 502~543(42 resistor)

               1018(1 resistor)

Then I made chart as an attachment file.

But Data of 1018 address is not normal status.

Was this wrong configuration?

I would like to know the configuration method information when I do to recieve data from separate address on one device.

Thank you.
