Comparison Instructions

 Overview of Comparison Instructions 
Description
IN1 and IN2 are compared according to the type of comparison you choose:
==  IN1  is equal to  IN2
<>  IN1  is not equal to  IN2
>  IN1  is greater than  IN2
<  IN1  is less than  IN2
>=  IN1  is greater than  or equal to  IN2
<=  IN1  is less than  or  equal to  IN2
If the comparison is true, the RLO of the function is "1". It is linked to the RLO of a rung network by
AND if the compare element is used in series, or by OR if the box is used in parallel.
The following comparison instructions are available:
•  CMP ? I    Compare Integer
•  CMP ? D      Compare Double Integer
