Part III FP Instructions
F131_BTR
16-bit data bit reset
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
d ANY16 16-bit area
n INT specifies bit position to be reset
For Relay T/C Register Constant
d - WY WR WL SV EV DT LD FL -
n WX WY WR WL SV EV DT LD FL dec. or hex.
Description
Turns OFF the bit specified by the bit position at n of the 16-bit data specified by d if the trigger EN
is in the ON-state. Bits other than the bit specified do not change. The range of n is 0 to 15.

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.
POU header
All input and output variables used for programming this function have been declared in the POU
header.
Body
When the variable start is set to TRUE, the function is carried out.
LD
ST
When programming with structured text, enter the following:
IF start THEN
F131_BTR( n:= 2,
d=> output_value);
END_IF;
