Behaviour
Falling below lower threshold
Exceeding upper threshold
Options: unchanged
ON
OFF
This parameter determines the switch state of the output in
dependence on the value of the communication object, if the value of
the communication object Threshold input of the upper or lower
threshold value is overshot or undershot.
A reaction only occurs if the communication object value was
previously smaller or larger than Threshold 1 or Threshold 2.
For further information see:
, page 152
With option no, the following parameters appear:
Object value < lower threshold
Lower thrsh. <= object <= upper thrsh.
Object value > lower threshold
Options: unchanged
ON
OFF
This parameter determines the switch state of the output (ON, OFF,
unchanged) in dependence on the threshold value (the value of the
communication object).
Object "threshold input" value
on bus voltage recovery (0...255)
Object "threshold input" value
on bus voltage recovery (0...65,535)
The value range is dependent on the selection in the parameter Data type of
object "Threshold input"
.
1 byte (0…255):
Options: 0…255
2 byte (0…65,535):
Options: 0…65,535
This parameter determines the value of the communication object Threshold
input
after bus voltage recovery.
The threshold value evaluation is carried out after bus voltage recovery
using the Threshold parameterised here, whereby the last Status Threshold
detected in operation is used for comparison. Should no Status Threshold
exist before bus voltage failure, the factory set status (hysteresis limit
undershoot) is assumed.
