Parameter:
ThresholdValue
Declaration:
INPUT
Data type:
INT
Range of
values:
0 / 1 ... 32767
Default:
270
Explanation:
Threshold value
When specifying the threshold value, take the encryption range of the analog
values into account. Raw values from S7 analog inputs are always encoded in
the range from 0 ... 27648 (= 0 ... 100 %) or + 27648 (= + 100%). Depending
on the resolution of the analog input, the value jumps by 128 (at 8
-bit resolu-
tion) or 1 (at 15
-bit resolution). If the acquired analog values have a different
encod
ing range, specify a threshold value oriented toward this.
If the parameter is not configured, the default value of 270 is used. This corr
e-
sponds to approximately 1% of the normal S7 analog raw value range.
Point to note with "ThresholdValue" = 0
Changes a
re not checked based on the threshold value. The analog value
frame will only be sent in the following situations:
•
When there is a trigger via the "TriggerInput" input, typically a time-driven
or event-driven trigger.
•
When there is a general request to the station or a single request for the
data frame.
•
When the analog value moves into the overshoot or undershoot range
(7FFF
H
or 8000
H
) (possibly after the suppression time set for
"FaultSuppressionTime" has elapsed).
When MeanValueGeneration = TRUE, i.e. the
analog values are sent as
mean values, the "ThresholdValue" parameter has no meaning.
Parameter:
SmoothingFactor
Declaration:
INPUT
Data type:
INT
Range of
values:
1 (no smoothing)
4 (weak smoothing)
32 (medium smoothing)
64 (strong smoothing)
Default:
1
