11.12 Information on the response of the status output
General information
If you have configured the status output for "LIMIT VALUE" (ä 132, ASSIGN STATUS function)
you can specify the required switch points in the ON-VALUE (ä 133) and OFF-VALUE
functions (ä 134).
If the measured variable in question reaches these predefined values, the status output switches as
shown in the illustrations below.
Status output configured for limit value
The status output switches as soon as the current measured variable undershoots or overshoots a
defined switch point.
Application: monitoring flow or process-related boundary conditions.
