Description
Finds the arc cosine of the specified data. (Units: [deg])
The specified data is real number type only.
The specified data is real number type only.
Finds the exponent of the specified data.
Finds the natural logarithm of the specified data. (Base: e)
Extracts the decimal portion of the specified data.
Extracts the sign of the specified data.
Value of specified data ≥ 0 → 1
Value of specified data < 0 → −1
• 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.
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.
According to the result of logic operation expression, the SET/RST command
turns ON or OFF the specified bit of the specified variable.
SET: Not executed as an independent command (no type).
RESET: Not executed as an independent command (no type).
<First term> = SET <logic operation expression>;
<First term> = RESET <logic operation expression>;
Ex: #MB01000 = SET #MB01001 & #MB01002;

Bit
No Yes
• 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.
