Outputs
ENO is the Real Divide enable out bit. This bit is enabled and
passes power when the enable bit is True, as long as the value
of RC does not go out of range.
RC is the quotient. RC contains the quotient of RA and RB as
long as the enable bit is True. The range of values this
Variable can assume is from -3.4x10
38 to 3.4x10 38 . No
remainders are stored in this value; only the whole number
value. If this Variable is assigned a value out of these ranges,
ENO is disabled. RC reverts to its last valid value whenever
ENO is disabled.
Real Move (RMOV)
The Real Move (RMOV) function block, shown in Figure
10.33, places the value of one Variable into another Variable.
RMOVE places the input Variable (RIN) value in the output
Variable (ROUT) while the enable bit (EN) is True. The output
bit (Q) always assumes the value of the enable bit; therefore,
when the enable bit is True, the output bit is also True. The
Variables for RIN and ROUT can be any type.

Inputs
EN is the Real Move enable bit. A True condition of this bit
causes the value of RIN to be copied to ROUT. In a program
using Ladder logic, the value of EN is determined by the
Boolean evaluation of elements placed between the left power
rail and EN in a Ladder Diagrams program. In FBD programs,
the value of EN is determined by the Variable connected to EN.
If no contacts are placed on the rung before EN in a Ladder
Diagram program, the value of EN is always True. In FBD, all
inputs must be connected to a Variable.
RIN is the Real Move input Variable. The range of values this
Variable can assume is from -3.4x10
38 to 3.4x10 38 . If this
Variable is assigned a value out of these ranges, unpredictable
results will occur.
