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 × 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 × 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
J
Work normally with analog inputs and setpoints as the
parameters for the analog value comparator.
J
The analog value comparator for EZ500 and EZ700
operates internally in the value range:
–2147483648 to +2147483647
This ensures that the correct value is always calculated.
This is important for multiplying values (I1 × F1 or I2 ×
F2).
Example:
I1 = 9999, F1 = 9999
I1 × F1 = 99980001
The result is within the value range.
J
If no value is entered at F1 or F2, only the value at I1 and I2
is used (no multiplication).
