TIM 1531 IRC
158 Operating Instructions, 02/2018, C79000-G8976-C468-02
Default:
500
Explanation:
Acquisition interval for analog inputs in milliseconds
The acquisition interval is required for the following parameters:
•
Threshold formation according to the integration principle
(ThresholdIntegration)
•
Smoothing the analog input value (SmoothingFactor)
The value must be selected high enough so that it is certain that a new value
was acquired within the encryption time of the analog input. The interval to be
specified has to be at least
as long as the encoding time of the analog input
module being used at the selected resolution (8 ... 15 bits).
The value must also be selected generously so that analog values are a
c-
quired even with the highest resolution and with analog modules with the
highest number of inputs.
Specifying a "SamplingPeriod" that is too short may lead to an overflow of the
internal accumulation counter.
Parameter:
ThresholdValue
Declaration:
INPUT
Data type:
REAL
Range of
values:
+1.175495e
-38 ... +3.402823e+38
Default:
1.0
Explanation:
Threshold value
Without configuration, the default value 1.0 is used.
Point to note with "ThresholdValue" = 0: Changes are not checked based on
the threshold value. The analog value frame will only be sent in the following
situation
s:
•
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.
Parameter:
SmoothingFactor
Declaration:
INPUT
Data type:
REAL
Range of
values:
1.0 (no smoothing)
4.0 (weak smoothing)
32.0 (medium smoothing)
64.0 (strong smoothing)
Default:
4.0
