Command Details
Section 6-3
• 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.
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.
6-3-9 Bit Operation
Specified Bit ON/OFF
(SET/RESET)
According to the result of logic operation expression, the SET/RST command
turns ON or OFF the specified bit of the specified variable.
Command type SET: Not executed as an independent command (no type).
RESET: Not executed as an independent command (no type).
Format <First term> = SET <logic operation expression>;
<First term> = RESET <logic operation expression>;
Ex: #MB01000 = SET #MB01001 & #MB01002;
Operand )
Description • If the logic operation expression on the right side is true, SET command
turns ON the bit specified on the left side.
• If the logic operation expression on the right side is true, RESET com-
mand turns OFF the bit specified on the left side.
