Hi! I am doing a project of making the S7-200 PLC*s
Modbus protocol as master protocol. Is this possible? Can
I do this through programming? Thank you very much.

The published Modbus Master sample contain the
Modbus-Master driver you need.
You find them at the sample section or type
on the left at ID: 24.

At the Tools section (ID: 25) you could download the
ModSim (Modbus Slave simulator). With this you could
simulate Modbus slaves for tests with your PC.
