Operands:
D: Destination device
Explanations:
1. 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.
2. This instruction adopts pulse execution instructions (INCP).
3. 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.
Program Example:
When X0 goes from Off to On, the content in D0 pluses 1 automatically.

Explanations:
1. If the instruction is not a pulse execution one, the content in the designated device D will
minus “1” in every scan period whenever the instruction is executed.
2. This instruction adopts pulse execution instructions (DECP).
3. In 16-bit operation, -32,768 minuses 1 and obtains 32,767. In 32-bit operation, -
2,147,483,648 minuses 1 and obtains 2,147,483,647.
Program Example:
When X0 goes from Off to On, the content in D0 minuses 1 automatically.
