Using Modbus RTU to send data to a Siemens CPU 313C.

I have Siemens CPU 313C. I need to acquire data through Modbus RTU. How can it be done?

Any external hardware/converter will be needed? please suggest

Hi MONAK,

You will need CP341 module in the S7 Rack (with a RS-485 interface and a licensed Modbus master loadable software)
