Enable thresholds
Options:
•
yes: The parameters and communication objects for threshold 1 for monitoring the Current value of
output A are enabled. The following parameters appear:
84 2CDC 505 084 D0203 | SE/S 3.16.1
no
yes
Overwrite thresholds with download
or ETS reset
Options: no
yes
•
yes: The threshold values can be modified via the bus. With this setting, after a download or
ETS reset, the values changed on the bus are again overwritten with the parameterized values.
This setting applies for threshold value 1 and threshold value 2.
Delay for switching in s [0...65,535]
Options: 0...1...65,535
Then output can switch in dependence on the threshold values of the current value. The switching
reaction occurs if the threshold exceeds or falls below the time parameterized here. This setting
applies for threshold value 1 and threshold value 2.
Evaluation of threshold 1
Options: only if contact is closed
only if contact is open
always
•
only if contact is closed: Threshold 1 is only evaluated when the contact is closed.
•
only if contact is open: Threshold 1 is only evaluated when the contact is opened.
•
always: Threshold 1 is evaluated independently of the contact position.
Note
The evaluation of threshold 1 occurs based on the "calculated" relay position, i.e. if manual
switching has occurred or if a contact has welded, this will not be considered.
Threshold 1 lower limit
in 100 mA x value [0...200]
Options: 0...1...200
This is the lower hysteresis limit of threshold value 1. If the lower threshold is undershot, there is a
reaction.
