Device involved in the getting of the
absolute value
Word/Double word
Explanation:
1. When the instruction ABS is executed, the absolute value of the value in the device specified
by D is gotten.
2. Generally, the pulse instruction ABSP is used.
3. Only the 32-bit instructions can use the 32-bit counter.
Example:
Suppose the value in D0 before the execution of the instruction is -1234. When X0.0 is switched
from OFF to ON, the absolute value of -1234 in D0 is gotten. That is, the value in D0 becomes 1234
after the instruction is executed.
