Event ID Event OB
W#16#3501 Cycle time exceeded. OB 80
W#16#3502 User interface (OB or FRB) request error OB 80
W#16#3503 Delay too long processing a priority class -
W#16#3505 Time-of-day interrupt(s) skipped due to new clock setting OB 80
W#16#3506 Time-of-day interrupt(s) skipped when changing to RUN after
HOLD
OB 80
W#16#3507 Multiple OB request errors caused internal buffer overflow OB 80
W#16#3508 Synchronous cycle interrupt-timing error OB 80
W#16#3509 Interrupt loss due to excess interrupt load OB 80
W#16#350A Resume RUN mode after CiR OB 80
W#16#350B Technology synchronization interrupt - timing error OB 80
W#16#3921/3821 BATTF: failure on at least one backup battery of the central
rack/ problem eliminated
Note: the event entering state only occurs if one of the backup
battery fails (if there are redundant backup batteries). If the
other backup battery should also happen to fail, the event will
not occur again.
