Data in bit position 15
When
n
bits are rotated to the left,
the data in bit position 16-
n
(
n
th bit starting from bit position 15) is transferred to special internal
relay R9009 (carry-flag).
n
bits starting from bit position 15 are shifted out to the left and into the lower bit positions of the
16-bit data specified by
d
.
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.
