800xA Alarms & Events: What does "Cen Man off Blk" means for a MOT1 ????
You have to interpret this way Cen Man Off Blk
[MODE] + [SUBMODE] + [STATUS] + [STOP REASON] + Blk: [BLOCK LIST]
Cen - your motor faceplate in Central mode and Man Off - Manual mode Motor is stopped.
Then finally Blk : which says there is no active interlock block on this motor.
Cen Man off Blk: IB1 - then you have an active block on interlock IB1.
