PLC monitor
Edge / level
The limit values are permanently configured in the variable monitor. Triggering for
several limit values of a variable is only possible via several variable monitors; this
is also true for each limit violation.
Notice
If several limit values are monitored in one monitor, triggering is not possible for
each individual limit violation. In this case, only the first limit violation results in a
trigger.

Description
 Reaches the critical limit
 Reaches the warning limit or critical limit
 Reaches the warning limit, but not the critical
limit
Any number of variables can be integrated into
the trigger.
Evaluate trigger:
If "Edge" is selected, the trigger will only be initi-
ated during the transition between the previous
and current instance of variable acquisition, while
simultaneously detecting the trigger initiation func-
tion. If "Level" is selected, the trigger will be initi-
ated each time the variable content is recorded,
once the initiating function has been detected.
The initiating function is the limit value function
that has been selected.
