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.

Variable Data type Function
s1 WORD augend, 16-bit area for 4-digit BCD data or equivalent constant
s2 WORD addend, 16-bit area for 4-digit BCD data or equivalent constant
d WORD sum, 16-bit area for 4-digit BCD data
For Relay T/C Register Constant
s1, s2 WX WY WR WL SV EV DT LD FL dec. or hex.
d - WY WR WL SV EV DT LD FL -
Description
The 4-digit BCD equivalent constant or 16-bit area for 4-digit BCD data specified by s1 and s2 are
added together if the trigger EN is in the ON-state. The result is stored in d.
