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, s2 16-bit area or 16-bit equivalent constant to be compared
d
ANY16
16-bit area for storing AND operation result
The variables s1, s2 and d have to be of the same data type.
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
Executes AND operation of each bit in 16-bit equivalent constant or 16-bit data specified by s1 and
s2 if the trigger EN is in the ON-state. The AND operation result is stored in the 16-bit area
specified by d. When 16-bit equivalent constant is specified by s1 or s2, the AND operation is
performed internally converting it to 16-bit binary expression. You can use this instruction to turn
OFF certain bits of the 16-bit data.

Example
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.
