Increment (D)+1 → (D)
Decrement (D) – 1 → (D)
In a 16-bit operation, when a value of “+32,767” is reached, the next increment of “1” will write a value of “-32,768”
to the destination device.
In a 32-bit operation, when a value of “+2,147,483,647” is reached, the next increment of “1” will write
a value of “-2,147,483,648” to the destination device.
When X20 = “OFF” → “ON”, the content value of destination (D100) will be increased by one.
If the instruction is not a pulse (P) instruction, the destination (D100) will increase its value in every scan cycle.
The instruction operation result will never lead to any change of a ag.
When X20 = “OFF” → “ON”, the content value of destination (D100) will be decreased by one.
If the instruction is not a pulse (P) instruction, the destination (D100) will decrease its value in every scan cycle.
In a 16-bit operation, when a value of “-32,768” is reached, the next decrement of “1” will write a value of “+32,767”
to the destination device.
In a 32-bit operation, when a value of “-2,147,483,648” is reached, the next increment of “1” will write a value of
“+2,147,483,647” to the destination device.
The instruction operation result will never lead to any change of a ag.
