Operands:

D: Destination device

Explanations:

1.If the instruction is not used in pulse execution mode, the content in the designated device D will plus “1” in every scan period

2.When INC is executed, the content in D will be incremented. However, in 16-bit instruction, if +32,767 is reached and “1” is added, it will write a value of –32,768 to the destination. In 32-bit instruction, if +2,147,483,647 is reached and “1” is added, it will write a value of -2,147,483,648 to the destination.

3.This instruction is generally used in pulse execution mode (INCP, DINCP).

4.If operand D uses index F, only a 16-bit instruction is applicable..

5.The operation results will not affect M1020 ~ M1022.

Program Example:

When X0 is triggered, the content of D0 will be incremented by 1.
