comparators:
Inputs
The function block inputs
>I1, >F1, >I2, >F2, >OS and
>HY can have the following operands:
•Constants
• Markers MD, MW, MB
• Analog inputs IA01 to IA04
– IA01: Terminal I7
– IA02: Terminal I8
– IA03: Terminal I11
– IA04: Terminal I12
• Analog output QA01
• Actual value …QV> of another function block

>I1 Comparison value 1
>F1 Gain factor for >I1 (>I1 = >F1 x value)
>I2 Comparison value 2
>F2 Gain factor for >I2 (>I2 = >F2 x value)
>OS Offset for the value of >I1
>HY Switching hysteresis for value >I2 (Value HY applies to
positive and negative hysteresis.)
