Command Details
Section 6-3
Precaution for Handling the Data Types
1,2,3... 1. Bit type
• When the bit type is used, all the operands must be the bit type.
• The integer immediate values 0 and 1 are treated as the bit type.
2. Types other than the bit type
• Types other than the bit type are prioritized in the following order
Real number type > Long word type > Word type
• Operation is performed in the type of the highest priority, and the op-
eration result will be stored after being converted to the type on the left.
• The integer immediate value is treated as long word type, and the dec-
imal immediate value is treated as real number type.
6-3-7 Logic Operation
Logic Operations (|,
&, ~)
This specified logic operation is executed.
Command type |, &, and ~: Not executed as an independent command (no type).
Format <First term> = <Second term> Operator <Third term>;
Ex: #MW1000 = #MW0010 & #MW0011;
Operand
Note For XOR (LOGICAL EXCLUSIVE OR) (~), the bit type cannot be used for
variables.
Description • The logic operation is executed with logic operators on each bit corre-
sponding to the second and third terms. The result will be output to the bit
corresponding to the first term.
• If the types are different on both sides, the type on the right is converted
to that of the left.
• If the value on the right side cannot be stored in the left side, the alarm
[2005h: Operation overflow] will occur.

Function Description
| OR (LOGICAL OR) Assigns the LOGICAL OR (OR) of the 2nd
and 3rd terms to the 1st term.
& AND (LOGICAL
AND) Assigns the LOGICAL AND (AND) of the
2nd and 3rd terms to the 1st term.
~ XOR (LOGICAL
EXCLUSIVE OR) Assigns the LOGICAL EXCLUSIVE OR
(XOR) of the 2nd and 3rd terms to the 1st
term.
