800xA 5.1 RU4 and TC3 upgrade, lost Ethernet/IP devices
We've ran our upgrades at our site for RU4 and TC3 upgrades to our 800xA system. At the same time we've upgraded the firmware on our controllers to 5.1.1400.15 on our PM891/PM866 controllers and our CI873 cards have been upgraded to 5.1.2401.00 firmware revisions.
We've did the cold download to the controllers, and we are no longer to communicate with any Ethernet/IP devices that we could before the upgrades. We've checked the vendor EDS files and they have not upgraded and are using the same revisions.
Any troubleshooting or things to check to get these devices back or is it revert back to the old firmwares?

Jason,
You could revert back firmware of CI873 in a seperate test system. There is no possibility to go back to old library(i.e old FW) once the system extension is run. I explained the procedure to Attila this morning, you may want to check with him.
