Process Interrupt of the IM 153-2
If the IM 153-2 reports a process interrupt, there is at least one data record
containing messages concerning time-stamped signal changes or special
messages.
The DP master CPU can read the data record(s) and evaluate them with
the 90 ”IM_DRV” FB (see the PCS 7 documentation).
Evaluation with FB 62 ”FB TIMESTMP” is also possible.
