HELLO COMMUNITY,

I am working on a project where Controller is S7-1200 G2 with one di/do module, ai module and one ao module and 3rd Party Scada and the communication is thorough the GSM Modem with Modbus TCP protocol.

Can any one suggest about how to Read and write Coil Register, Input Register, Input Bits and Holding Register in S7-1200 PLC through Modbus TCP Server Block

If any Sample will be available then it will be helpful.
