Hysteresis for limit value,
HY-1:
Default:
0000
The hysteresis defines a difference to the limit value by which an alarm reacts delayed.
Function for limit value undercut/ limit value exceeded,
FU-1
:
Default:
hi9h
The limit value violation is selected with
Louu
(for LOW = lower limit value) and that with
HiGH
(for
HIGH = upper limit value). Derived from "lower limit" = lower limit value and higher limit = upper
limit value. If, for example, limit value 1 is set to a switching threshold of 100 and assigned the
function
high
, the alarm is activated when the switching threshold is reached. If the limit value is
assigned to
Low
an alarm is triggered when the value falls below the switching threshold,
provided that the hysteresis is zero.
Limit values,
LI-2
:
Default:
0300
The limit value specifies the threshold above which the alarm reacts or is activated/deactivated.

as the hysteresis is zero.
