Hello,
look heresiemens it's the 7. example.

Hi lorenz2512,



Thank you! I try this program and now I can do Modbus Slave Communication with S7-200.

Siemens sells an add-on instruction library for the S7-200 that includes Modbus and USS (their drive protocol). Might be worth looking into?

Hi All;

Which communication protocols integrated to S7-200 and which communication protocols using by modules.
