3.4.13 Server trigger on "Variable monitor reaches limit value"

Function description
Any reaching or exceeding of the limit values defined in the variable monitor can be
configured here as a trigger in the control monitor.
In contrast to the interval-based evaluations, an ePS Network Services endless
counter should not be used here; otherwise, it will only possible for a trigger to be
initiated once over the course of the entire life cycle of the monitor. In this case, it is
advisable to use the normal PLC variable, which can fluctuate around a limit value
so that this monitor can become active each time a limit value is violated.
Since the variable monitor cannot generate an entry in the event history, this is do-
ne via the control monitor to ensure that any limit value violations can be docu-
mented.
The further functions of the control monitor, with workflow actions and diagnostics
actions, are fully available, in order to be able to interactively initiate actions in re-
sponse of limit value violations. Since the processed data is not updated cyclically,
the evaluation is done by reaching or exceeding the limit. In order not to trigger an
action at every triggering, edge evaluation can be selected. An event will be gener-
ated only at the first trigger after the limit value violation.
