Short description 
The average value function calculates the average value of an analog input over a 
configured time period.

Description 
En 
A change in status from 0 to 1 transition at input En 
starts the average value function.  
A change in status from 1 to 0 at input En holds the 
analog output value.  
R 
A signal at input R clears the analog output value. 
Ax 
Input Ax is one of the following analog signals:  
• 
AI1 to AI8 (*) 
• 
AM1 to AM16 
• 
NAI1 to NAI32 
• 
AQ1 to AQ2 
• 
NAQ1 to NAQ16 
• 
Block number of a function with analog output 
Parameter 
St (Sampling time): You can set the timebase to s 
(seconds), d (days), h (hours), or m (minutes).  
Range of values: 
St = s: 1 to 59  
St = d: 1 to 365  
St = h: 1 to 23 
St = m: 1 to 59 
Sn (Number of samples):  
Range of values: 
St = s: 1 to St*100 
St = d: 1 to 32767 
St = h: 1 to 32767 
St = m and St ≤ 5 minutes: 1 to St*6000 
St = m and St ≥ 6 minutes: 1 to 32767 
Retentivity: 
/ = No retentivity 
R = Retentivity

Output AQ 
Outputs the average value of input Ax over 
configured time sampling period.  
* AI1...AI8: 0...10 V corresponds with 0...1000 (internal value).
