Hi,
to be able to communicate with a PLC from a RPI, I decided to use libmodbus on my RPI and Visilogic on my PLC.
RPI = server / PLC = client
I would like to get request from the PLC and send appropriated data to him.
However, I didn't succeed in getting response after modbus_receive. I am always waiting answers of the PLC wheread he's sending requests.
Did you already work with a modbus communication with a PLC (and Visilogic software) ?
