Hi all,
I have aproject which requires my S7-200 to communicate with the PDMS through Modbus communcation.
I must send some data to the PDMS, and recieve other control signals from the PDMS.
As 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 must send the PDMS the folloing points:
Inputs f the PLC (total of 55 inputs).
Outputs of the PLC (total of 40 outputs).
Memory locations (regesters I use them in my control and I must inform the PDMS about them).
I must recieve from the PDMS about 10 control points.
Any one can help me with that,
Does any one have sample programs using the modbus can share it.
