4.4 Analog value comparator/threshold value switch
easy provides 16 analog comparators A1 to A16 for use as required. These
can also be used as threshold value switches or comparators.
An analog value comparator or threshold value switch enables you to
compare analog input values with a setpoint, the actual value of another
function relay or another analog input. This enables you to implement small
controller tasks such as two-point controllers very easily.
All easy-AB, easy-DA and easy-DC devices are provided with analog inputs.
•
The analog inputs of the easy500 are I7 and I8.
•
The analog inputs of the easy700 are I7, I8, I11 and I12
A1…A16 analog value comparator
Boolean inputs/outputs
Parameters
Contact
Coil
Input value
Output value
A..
1 if the selected actual
value/setpoint
condition is fulfilled.
I1
Comparison value 1
F1
Gain factor for I1 (I1 = F1 *
value)
I2
Comparison value 2
F2
Gain factor for I2 (I2 = F2 *
value)
OS
Offset for the value at I1,
I1
OS
= OS + actual value at I1
HY
Switch hysteresis for value at
I2 (value HY is used for both
positive and negative
hysteresis.)

Compatibility with easy400 and easy600
If you are loading an existing easy400 or easy600 circuit
diagram, the existing comparison functions and values are
retained. The analog value comparison function relay works in
easy500 and easy700 and in easy400, easy600. The setpoints
are converted to the new resolution of the analog inputs. The
setpoint 5.0 (easy400, easy600) is converted to the setpoint 512
(easy500, easy700).
