If the instruction is not used in pulse execution mode, the content in the designated device D will plus “1” inevery scan period2. When INC is executed, the content in D will be incremented. However, in 16-bit instruction, if +32,767 is reachedand “1” is added, it will write a value of –32,768 to the destination. In 32-bit instruction, if +2,147,483,647 isreached and “1” is added, it will write a value of -2,147,483,648 to the destination.3. When INC is used as 16-bit instruction, Z device cannot be adopted; when INC is used as 32-bit instruction, Vdevice cannot be adopted.4. This instruction is generally used in pulse execution mode (INC P, DINC P).Program Example:When X0 is triggered, the content of D0 will be incremented by 1.X0INCP D0
