Not able to go online with some older 500 series processors. I have went online with the processors in the past, something changed. I get "no response from the processor" window and when I go to system comms I see the SLC504 or 505 in the ethernet tree but When I select online/upload the highlight goes away from my target and it does nothing. I believe it is a path issue but I don't know how to resolve. I try all of the engineering stations available with no success. Any asset center gurus on today? If so I will join your ashram...heads already shaved. Thanks
