Behaviour
Falling below lower threshold
Exceeding upper threshold
Options:
no reaction
ON
OFF
This parameter determines the contact position of the output based on the value of communication
object
Threshold input
if this value exceeds or falls below the upper or lower threshold respectively.
A reaction only occurs if the communication object value was previously smaller or larger than
Threshold 1 or Threshold 2.
For further information see:
Threshold function
, p. 159
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 contact position of the output (ON, OFF, unchanged) based on the
threshold (communication object) value.
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 made 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 communication object
Threshold input
after bus voltage recovery.
Threshold value evaluation is carried out after bus voltage recovery using the threshold parameterized
here, whereby the last
Status Threshold value
detected in operation is used for comparison. Should no
Status Threshold value
exist before bus voltage failure, the factory-set status (hysteresis limit undershoot)
is assumed.
