Examples

In this example we are setting the value of “My_DINT” to the value 3000.
In this example we are incrementing the value of “My_DINT” by 1. Similarly we could have selected the -1 operation and then decremented the value of “My_DINT by 1. Please note that the 2nd Operand is not needed for this operation .
In this example we are adding 5 to the initial value of “My_DINT” and placing the result in “My_DINT”
