Saffari Posts: 7 Rating: (0)	Thankyou Umencho, As I know, SFB20 is used to stop one plc from remote plc. How is it possible to load a project with two cpu in PLCSIM? Do you have any example to simulate SFB20?

I guess you can only see result of calling this SFB20 in your CPU. If there is a rising edge at control input REQ, SFB 20 "STOP," this activates a change to the STOP mode on the remote device addressed by the ID. The mode change is possible when the device is in the RUN, HOLD or STARTUP modes... Hope this will helps. Best regards. Hristo Mihalev
