PM865 HI Controller Errors with AI880
A customer is having problem with the PM865 HI Controller on site. It seems like the problems are related to all the AI880 cards connected to the controller. This generates channel errors and then shut down the plant. I have attached the log file of the controller.
These problem seems to have occured only after a maintenance shut down. During this shut down they have changed the loop isolators in the field, and they have performed a firmware upgrade using the 800xA 5.1 Fp4 RevE media. From the log file it seems like these problems occurred only after the firmware upgrade.
Could this be related to firmware and IO card incompatibility/bug? Or could this be a hardwired problem i.e loop isolators, etc.
