![]() ![]() I must recieve from the PDMS about 10 control points.ĭoes any one have sample programs using the modbus can share it. Memory locations (regesters I use them in my control and I must inform the PDMS about them). Outputs of the PLC (total of 40 outputs). I must send the PDMS the folloing points: I must send some data to the PDMS, and recieve other control signals from the PDMS.Īs I understand from the S7-200 manual, the PLC can act as a master (sending Data), and a slave (Recieving data), Can the PLC work as both sending and recieving data at the same time, or its a totally different concept. I have aproject which requires my S7-200 to communicate with the PDMS through Modbus communcation.
