I have a problem with RSLinx Lite Classic. When I connect to the PLC, i can see the PLC (CompactLogix), but cannot see any of the modules connected. Please help.
I am trying to connect with an existing system. I have connected to it before, but today I was about to online edit when I noticed in RSLinx that one module is missing. Then I power cycled, and after that there are no modules shown in RSLinx, just the PLC.
Refer to post #2 in the following thread for a reference to Rockwell Technote #769010 about clearing the RS-Linx cache. There is a small chance this will resolve the issue described.
