Gets the absolute value of 32-bit data with the sign specified by d if the trigger EN is in the

ON-state. The absolute value of the 32-bit data with sign is stored in d. This instruction is useful for

handling data whose sign (+/-) may vary.

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.

Instead of using this FP instruction, we recommend using the related IEC instruction ABS (see

page 66). Please refer also to Advantages of the IEC instructions in the online help.

Availability of F88_DABS (see page 1326)

In this example, the same POU header is used for all programming languages. For an example

using IL (instruction list), please refer to the online help.

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