Operands:
D
: Destination device
Explanations:
1. If
D
is used in device F, only 16-bit instruction is applicable.
2. See the specifications of each model for their range of use.
3. If the instruction is not a pulse execution one, the content in the designated device D will plus “1” in every scan
period whenever the instruction is executed.
4. This instruction adopts pulse execution instructions (INCP, DINCP).
5. In 16-bit operation, 32,767 pluses 1 and obtains -32,768. In 32-bit operation, 2,147,483,647 pluses 1 and
obtains -2,147,483,648.
6. The operation results will not affect M1020 ~ M1022.
Program Example:
When X0 = Off
→
On, the content in D0 pluses 1 automatically.
