Extension due to nesting of higher-priority OBs and/or interrupts
The interruption of a user program at the end of an instruction by a higher-priority OB causes
a certain basic time expenditure. Take account of this basic time expenditure in addition to
the update time of the assigned process image partitions and the execution time of the
contained user program. The following tables contain the typical times for the various
interrupts and error events.
