Hope someone can help. I have a Windows 7 machine running RSLogix 500 Pro ver. 8.10 and RSLinx classic ver. 2.59. When i try to go online or any of the other functions the program stalls and i recieve a "DiagnosticStatus failed: 0xfffffffD" message. I am able also to see the 1100 i am trying to connect to in RSwho, but when i right click to view the data files, it tells me "Processor contains no data files", but i can connect with another machine and view the program with out issue.
Any help would be appreciated.
