Outputs
Q is the Boolean output bit.
ROUT is the REAL result of the SCL operation. The value is
based on the settings for RMAX and RMIN. ROUT retains its
previous value whenever EN is disabled. See Figure 10.25.

Real Number Function Blocks
Real function blocks are similar to regular standard function
blocks in LogicPro. As the name implies, real function blocks
use real Variables to perform calculations. In turn, the output
of these function blocks is also real. These function blocks are
found in the standard category.
Real Greater Than (RGT)
The Real Greater Than (RGT) function block, as shown in
Figure 10.26 on page 146, tests if a real Variable value is
greater than a reference value.
Like the Greater Than function block, RGT tests whether one
value (RA) is greater than another value (RB) when the enable
bit (EN) is True. If the relationship RA>RB is True, then the
output bit (Q) is enabled. The output bit is disabled either
when the enable bit becomes False or the value of RA is no
longer greater than RB. The values of A and B can be preset to
a constant or assigned a symbolic name, which allows their
value to change dynamically within the program.
