![]() It is actually the network module that implements a fair amount of the network protocol stack (AB never makes this easy!), so this seems possible. I seem to remember someone suggesting that you explicitly add a network module to the emulator and then use that IP address to access it. I think this is less likely as the error is fairly explicit but I could be translating the error incorrectly. This will tell the library that the PLC is a Micro800 family PLC which speaks a limited dialect of the protocol. Perhaps the emulator only handles the older ForwardOpen packets. Usually 1 is the back plane, 2 is Channel A (if there is one), and 3 is Channel B (if there is one). If the port is not right, then perhaps you can try other numbers. ![]() It does look like the CPU should be in slot 1, so 1,1 would be what I would normally expect. The error you saw with the ForwardOpen is definitely what is causing the library to stop trying. ![]() I have had people try with the emulator in the past, but they did not get this far. ![]() Thanks for the questions and excellent data to show what you have done! In the future, please start a new issue so that others can search this. ![]()
