4.4.1 Circuit diagram display with analog value comparator
Analog value comparators are integrated as contacts in the circuit diagram.
In the circuit diagram above, I1 enables both analog value comparators. If a
value goes below the set value, A1 switches output Q1. If another value
exceeds the set value, A2 deactivates output Q1. A3 switches marker M1 on
and off.

A1 Analog value comparator function relay 1
EQ Equal mode
The function relay has the following modes:
•
LT: less than
•
LE: less than/equal to
•
EQ: equal to
•
GE: greater than/equal to
•
GT:greater than

I1 Comparison value 1 (positive value I7, I8, I11, I12, actual value T1 to T16, C1 to C16)
F1 Gain factor for I1 (I1 = F1 x actual value at I1); F1 = positive value from 0 to 9999
I2 Comparison value 2 (positive value I7, I8, I11, I12, actual value T1 to T16, C1 to C16)
F2 Gain factor for I2 (I2 = F2 x actual value at I2); F2 = positive value from 0 to 9999
OS Offset for the value of I1 (I1 = OS + actual value at I1); OS = positive value from 0 to 9999
HY Switching hysteresis for value I2
Value HY applies both to positive and negative hysteresis.
•
I2 = Actual value at I2 + HY;
•
I2 = Actual value at I2 - HY;
•
HY= positive value from 0 to 9999

Work normally with analog inputs and setpoints as the
parameters for the analog value comparator.
