Overview of the combinatory logic operators
The following operators can be used:
Logical (Boolean) operators
The logical operators work only on actuators and resultants of type
bool
.
Syntax example Description Operator
Destination := Source1 AND Source2 ...
AND Source8 Logical AND operator.
1 if all source signals are 1. AND
Destination := Source1 OR Source2 ... OR
Source8 Logical OR operator.
1 if at least one of the source sig-
nals is 1. OR
Destination := Source1 XOR Source2 ...
XOR Source8 Logical exclusive OR operator.
1 if odd number of source signals
are 1. XOR
Destination := NOT Source Inverted value NOT
Arithmetic (integer) operators
The arithmetic operators work only on actuators and resultants of type
INT32
.
Syntax example Description Operator
Destination := S Source2 Add integer value. +
Destination := Source1 - Source2 Subtract integer value. -
Destination := Source1 * Source2 Multiply integer value. *
Destination := Source1 / Source2 Divide integer value. See also the
operator DIV.
Note
Division by zero is undefined. If
the denominator is zero, then the
quotient keeps its current value.
/
Destination := Source1 < Source2 Compares two integer values and
produces a Boolean result. <, <=, ==, >,
>=, !=
Destination := Source1 != Source2
(smaller than, smaller/equal, equal,
larger than, larger/equal, not
equal)
...
Destination := ABS Source Absolute value of integer. ABS
COPY(Source, Destination1, Destina-
tion2,...,Destination8) Copy integer value.
Copy integer value from source to
up to eight destination signals. COPY
