See below for assigning connections (inputs and outputs).
The function block calculates the following based on signals received at inputs IN 1
– IN 5:
Function types
•
Selection of minimum input signal (MIN)
•
Selection of maximum input signal (MAX)
•
Calculation of average value (AVR)
When configuration parameter SPLIT is active, the above calculations are applied
separately to these 2 ranges:
Configuration
parameter SPLIT
•
Inputs IN 1 – IN 2
•
Inputs IN 3 – IN 5
The calculations do not consider non-configured inputs.
Note
6.2
Assign inputs
The function block is activated through the following assignments:
Activate function block
•
At least 1 analog input Xx,
and
•
At least 1 of the 2 outputs Y1 or Y2.
Each analog input Xx can be assigned with a valid identifier to function block MIN-
MAX-AVR. Valid identifiers are TEMP, %, 0.0, and 0000.
Valid identifiers
When calculating the average, the first input IN 1 can be assigned more weight via
configuration parameter FACTIN1 .
Note on averaging
Example:
Enter average value of 5 signals at input 1 and provide signals to the other 4
inputs.
Result:
The output provides the average of 9 input signals.
