4.1 PS501 Control Builder Operators Overview

Name Meaning
Arithmetic Operators
ADD Addition
MUL Multiplication
SUB Subtraction
DIV Division
MOD Modulo division
MOVE Assignment of a variable to another variable of
an appropriate type
INDEXOF find the internal index for a POU
SIZEOF determine the number of bytes required by the
given variable
Bitstring Operators
AND Logic AND
OR Logic OR
XOR Logic XOR
NOT Negative
Bit-Shift Operators
SHL
Bitwise left-shift of an operand : erg:= SHL
(in, n) in gets shifted to the left by n bits.
SHR Bitwise right-shift of an operand: erg:=
SHR (in, n) in gets shifted to the right by n
bits.
ROL
Bitwise rotation of an operand to the left:
erg:= ROL (in, n) in will be shifted one bit
position to the left n times while the bit that
is furthest to the left will be reinserted from
the right.
ROR Bitwise rotation of an operand to the right:
erg = ROR (in, n) in will be shifted one bit
position to the right n times while the bit
that is furthest to the left will be reinserted
from the left.
Selection Operators
SEL Binary selection
MAX Maximum function
MIN Minimum function
LIMIT MAX is the upper and MIN the lower limit for
the result
MUX Multiplexer
Comparison Operators
GT Greater than
LT Less than
LE Less than or equal to
