Hardware interrupt with time stamping of digital input signals
If the IM 153-2 reports a hardware interrupt, this means that at least one data record contains
messages concerning time-stamped signal changes or special messages.
The DP master CPU can read the data record(s) and evaluate them with the FB 90 "IM_DRV"
(see PCS 7 documentation).
In the same way, it is possible to evaluate with the FB 62 "FB TIMESTMP".
