Hysteresis for limit values,
Default:
The delayed reaction of the alarm is the difference to the threshold value, which
is defined by the hysteresis.
Function for threshold value undercut / exceedance,
Default:
A limit value undercut is selected with
(for LOW = lower limit value), a limit
value exceedance with
(for HIGH = higher limit value). If e.g. limit value 1 is
on a threshold level of 100 and allocated with function
, an alarm is activated
by reaching the threshold level. If the threshold value was allocated to
an
alarm will be activated by undercutting the threshold value, as long as the
hysteresis is zero.
Threshold values / limits,
Default:
This value defines the threshold, that activates/deactivates an alarm.
