6.5.45 Average value
Short description
The average value function samples the analog input signal during configured time period and outputs the
average value at AQ
Connection Description
Input En A positive edge (0 to 1 transition) at input En (Enable) sets the output AQ to the average value
of input Ax after the configured time. A negative edge (1 to 0 transition) holds the output at its
last calculated value.
Input R A positive edge (0 to 1 transition) at input R (Reset) resets the output AQ to 0.
Input Ax Input Ax is one of the following analog signals:
Analog Inputs
Analog Outputs
Analog Flags
The block number of a function with analog output
Parameter St (Sampling time): You can set it to Seconds, Days, Hours or Minutes.
Range of values:
If St = Seconds: 1 to 59
If St = Days: 1 to 365
If St = Hours: 1 to 23
If St = Minutes: 1 to 59
Sn (Number of samples):
Range of values:
If St = Seconds: 1 to St*100
If St = Days: 1 to 32767
If St = Hours: 1 to 32767
If St = Minutes and St ≤ 5 minutes: 1 to St*6000
If St = Minutes and St ≥ 6 minutes: 1 to 32767
Output AQ
AQ outputs the average value over the specified time of sampling.
* Analog Inputs: 0 to 10 V corresponds with 0 to 1000 (internal value).
Parameter St and Sn
Parameter St represents the sampling time and parameter Sn represents the number of samples.
