Hi friend, How to write a logic to control Micomaster440 with USS communication using S7-300 PLC.
I want a standard program to simulate it.

Aha, I did not know that. The CP340 only supports ASCII and 3964R. I guess then that the USS protocol is realised in STEP7 code and ASCII mode.JRW said:I agree, profibus is much better BUT,
Actually it is pretty common and you dont need a CP341 with any loadable drivers- a CP340 with the DriveES Simatic blocks- called "USSS7" works very well. It is basically a send block and receive block.
