Bit-shift instructions
F108_BITR
The function shifts the bits of a specified data range, whose beginning and end are specified by the
Description
outputs d1 and d2 to the right. The number of bits by which the data range is to be shifted to the
right is specified by the value assigned at input n. The value may lie between 0 and 16. Bits
cleared because of the shift become 0. When input n = 0, no shift takes place. When input n = 16,
a shift of one WORD occurs, i.e. the same process takes place as with function F110_WHSL (see
page 573).
start: ON
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.
