Error code Variable Bit Description
OB80_OB_PRIORITY Priority class of the OB causing the error
OB80_OB_NUM Number of the OB causing the error
05h and 06h Elapsed time-of-day interrupt due to moving
the clock forward
Elapsed time-of-day interrupt on return to
RUN after HOLD
OB80_ERROR_INFO Bit 0 = "1" The start time for time-of-day interrupt 0 is in
the past
... ....
Bit 7 = "1" The start time for time-of-day interrupt 7 is in
the past
Bit 15 ... 8 Not used
OB80_ERR_EV_CLASS Not used

OB80_OB_PRIORITY Not used
OB80_OB_NUM Not used
07h meaning of the parameters see
error code 02h
Overflow of OB request buffer for the current
priority class
(Each OB start request for a priority class will
be entered in the corresponding OB request
buffer; after completion of the OB the entry
will be deleted. If there are more OB start
requests for a priority class than the max-
imum permitted number of entries in the cor-
responding Ob request buffer OB 80 will be
called with error code 07h)
08h Synchronous-cycle interrupt time error
09h Interrupt loss due to high interrupt load
0Ah OB80_ERROR_INFO Resume RUN after CiR (Configuration in
RUN) CiR synchronizations time in ms
6.9.2 OB 81 - PS_FLT - Power Supply Error
The operating system of the CPU calls OB 81 whenever an event occurs that is triggered
by an error or fault related to the power supply (when entering and when outgoing event).
The CPU does not change to the STOP mode if OB 81 is not programmed.
You can disable or delay and re-enable the power supply error OB using SFCs 39 ... 42.
The following table describes the start information of the OB 81 with default names of the
variables and its data types:
