Dear all,

i heard that: you could simu more than one PLC in the PLCSim for testing communication ( Master/Slave; Profibus-DP...), but i can open 2 or more PLC in PLCSim. So please tell me the way i can do that or explain to me why no? and if you have an example about testing communication bewteen 2 PLC, please upload it here.

Thanks much,
