Bitwise Boolean instructions
F5_BTM
1 bit of the 16-bit data or constant value specified by s is copied to a bit of the 16-bit area specified
Description
by d according to the content specified by n if the trigger EN is in the ON-state. When the 16-bit
equivalent constant is specified by s, the bit data move operation is performed internally converting
it to 16-bit binary expression.
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.
The operand n specifies the bit number as follows:
n: 16#
For example, reading from the right, n = 16#C01 would move from bit position one, one bit to bit
position 12 (16#C).
