Arithmetic instructions

Adds "1" to the 32-bit data specified by d if the trigger EN is in the ON-state. The result is stored in

Example value 131081

31 . . 28 27 . . 24 23 . . 20 19 . . 16

Result value 131082 if trigger is ON

31 . . 28 27 . . 24 23 . . 20 19 . . 16

This instruction also exists as a P instruction (for FP2/2SH, FP3/5, FP10/10SH PLC types), which

is only executed at the rising edge of the EN trigger. Select [Insert P instruction] from the

"Instructions" pane if you require a P instruction. To facilitate reuse, the instruction then appears

under "Recently used" in the pop-up menu. Press <Ctrl>+<Shift>+<v> within the programming

area to open the list of recently used elements.

Availability of F36_DINC (see page 1325)

In this example the function has been programmed in ladder diagram (LD) and structured text

(ST).The same POU header is used for all programming languages.

All input and output variables used for programming this function have been declared in the POU

When the variable start changes from FALSE to TRUE, the function is carried out.

32-bit increment

32-bit area to be increased by 1

for an instant

15 . . 12 10 . . 8 7 . . 4 3 . . 0

15 . . 12 10 . . 8 7 . . 4 3 . . 0

 the calculated result is 0.

 the result exceeds the range of 32-bit

data (overflow).
