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.

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
