3.22.7.2 Functionality
The real greater than or equal comparator function GER compares the real input
REAL_IN1
with the real input
REAL_IN2
and activates the binary output
OUT
if
REAL_IN1
is equal to or greater than
REAL_IN2
-
TOLR
or greater than input
REAL_IN2
. That is, if
REAL_IN1
≥ (
REAL_IN2
-
TOLR
) or
REAL_IN1
> (
REAL_IN2
),
OUT
= 1, else
OUT
= 0.
If inputs
REAL_IN1
or
REAL_IN2
are outside the range, then
OUT
is set to 0.
