We just upgraded to 7.5 and none of our Logix (control and compact) devices will connect. They just say browse pending. The SLC505s and micrologix are working fine.

Can you try deleting all your tag cache files (all the .tags files in the […]/data/drivers directory) and restart the ABDrivers module?

The same thing happened to me but only for 1 CompactLogix PLC the others connect fine.

Followed Kevin’s instructions and the PLC connected ok again.
