AC800M ERRORS AND WARNINGS
IM GETTING A CHANNEL ERROR.
CAN ANYONE TELL ME HOW TO RECTIFY THESE ERRORS OR IS THERE ANY MANUAL PROVIDED BY ABB WHICH LISTS THE REMEDY FOR THESE ALARMS AND WARNINGS..
It seems the backup CPU lost connection to Control Network and that caused backup CPU fault (there is about 1 sec between that error messages).
Check the connections between CN1 and/or CN2 of the backup CPU and the control network.
Also flashing of LED's for CN1 and/or CN2 could give you some indication.
Then you have to reset the backup CPU and check if redundant mode is enabled (DUAL LED should light after about 1 min).
There are a lot of manuals available for AC800M controllers and system itself.
For example, look in system help files (F1), manuals installed with the system (pdf), also many available in the Internet, free access.
Kindly find attached controller log files.Right now i'm having only the redundancy enabled warning on the CPU.The module bus has +24vdc connected only to terminals RPA. If possible can i have a document mentioning a (HEX VALUE) for the latched error and warnings,extended status as the manuals has only the bit position for all modules.
