Hello
I have a HMI GT2220 from telemecanique.
I have a problem connecting it with a plc.
I defined an external variable (with a specific address in PLC) in vijeo designer. Now I want to connect it via modbus to plc (also telemecanique). I tried two different connection: modbus RTU, modbus RTU slave
But the data cannot be read from the plc.
Does anyone know how to define the HMI master with a specific address?
thank you so much
