Compare Real instruction is used to compare two
values: IN1 to IN2. Comparisons include: IN1 = IN2,
IN1
==R
IN1 >= IN2, IN1 <= IN2, IN1 > IN2, IN1 < IN2, or
IN2
IN1 <> IN2.
Real comparisons are signed.
==R
In LAD, the contact is on when the comparison is true.
In FBD, the output is on when the comparison is true.
In STL, the instructions Load, AND, or OR a 1 with the
IN1, IN2
top of stack when the comparison is true.
