been taken into service, the last communicated threshold value can be used. Basically,
a temperature range is given, in which the threshold value can be changed (object
value limit).
A set threshold value will be retained until a new value or a change is transferred. The
current value is saved, so that it is retained in the event of a power supply failure and
will be available once the power supply is restored.
Set the
hysteresis
independent of the type of threshold value specification.
Switching output
Set the behaviour of the switching output when a threshold value is exceeded/under-
cut. The output switching delay can be set using objects or directly as a parameter.
