Part III FP Instructions
F87_ABS
16-bit data absolute value
The absolute value of the 16-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.
