Search for clearing RSLinx harmony. It should appear on the forum search.
It's sort of like rebooting Windows for RSLinx. I have had times where RSLinx showed a SLC as faulted when it wasn't and could go online with it.
Close RSLinx, delete the 2 files (and only 2 - not 3) then reopen RSLinx. I don't have the file with me but it is simply deleting 2 files in the Program Files/Rockwell/RSCommon - might be the (x86) files, and either Rockwell Automation or Rockwell Software.
