Operands:
D
: Destination
Description:
1. If the instruction is not in pulse mode, “1” is added to the value of the destination
D
every
execution of the instruction, which could be every scan.
2. This instruction works best using pulse mode (INCP, DINCP).
3. In the 16-bit instruction, when +32,767 is reached, “1” is added and it will write a value
of –32,768 to the destination. In 32-bit instruction, when +2,147,483,647 is reached, “1” is
added and it will write a value of -2,147,483,648 to the destination.
4. Flags M1020~M1022 won’t be affected by the operation result of this instruction.
5. If operand
D
uses index register F, then only 16-bit instruction is available.
Program Example:
When X0 = OFF
→
ON, the content of D0 will be incremented by 1.
