Fatal Error AC800M PM864
The controller PM864 failed and when the secondary controller entered, it did not have the program. I see the controller log but I dont know how interpret it
It seems that module 3 (CI860) whas having some hardware issues right before the fatal error. It could be that the messages overloaded the controller. I would suggest to check the HwStatus bits of the CI860:
W 2017-10-19 16:56:43.752 On Unit= 3 HWError C75_Es~Bombeo4 0000 See HWTree Error 16#00000010 16#00000000
The secondary controller probably reacted the same as the primary controller since they share the same CI860, so it also stopped.
You can always contact your local ABB support to analyse a controller logfile, they can sometimes get more information from the logfile.
Hope this helps in the right direction.
