converter 

9.1 

Min-max-average 

 

 

 
"Min-Max-Average" executes the following calculations from the signals from inputs 
1 to 5: 

Purpose 

  Selection of minimum input signal (Min). 

  Selection of maximum input signal (Max). 

  Calculation of average value (Avr). 

 
2 "Min-Max-Average" blocks are available: 
The calculated values are provided as DC 0…10 V signals (Y) and internal, analog 
signals (a). 
 
The calculations do not consider non-configured inputs.

Function range B: Inputs 3 to 5. 

  The calculations are carried out on all configured inputs if "Inputs split" is 

disabled (factor setting No).
