F133_BTT
Checks the state [1 (ON) or 0 (OFF)] of bit position n in the 16-bit data specified by d if the trigger
Description
EN is in the ON-state.
The specified bit is checked by special internal relay R900B.
When specified bit is 0 (OFF), special internal relay R900B (=flag) turns ON.
When specified bit is 1 (ON), special internal relay R900B (=flag) turns OFF.
n specifies the bit position to be checked in decimal data.
Range of n: 0 to 15
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.
