Part III FP Instructions
F27_SUB2
16-bit subtraction, destination can be specified
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 SUB (see
page 62). Please refer also to Advantages of the IEC instructions in the online help.

Description
Subtracts the 16-bit data or 16-bit equivalent constant specified by s2 from the 16-bit data or 16-bit
equivalent constant specified by s1 if the trigger EN is in the ON-state. The result is stored in d. All
16-bit values are treated as integer values.
