2.17 DCMP Function Block

Description
The DCMP label stands for Deviation Compare. This block is part of the Calculations category. It looks
like this graphically on the Control Builder.
Function
Compares up to 6 analog inputs to a + or - user-entered deviation setpoint to a 7
sets the output true if any input exceeds the deviation value from the reference value. Output is off if all
inputs are less than the deviation.
Note: When the reference input is the average of the 6 inputs, the block performs deviation from average.
Input
IN1 = Input 1
IN2 = Input 2
IN3 = Input 3
IN4 = Input 4
IN5 = Input 5
IN6 = Input 6
Y =Reference Input
Note: All inputs should be used or a single value should be connected to multiple inputs. Unused inputs
will default to 0.
Output
OUT = Hi (1) when any input exceeds the specified deviation from the reference value.
