Description
Rotates "n" bits of the 32-bit data specified by D to the left when the trigger turns on.

Content of MSB
When "n" bits are rotated to the left,
− The data in bit position 32-n (nth bit starting from bit position 31) is transferred to special internal
relay R9009 (carry flag).
− "n" bits starting from bit position 31 are shifted out to the left and then shifted into the lower bit
positions of the 16-bit data specified by D.
Only the lower eight bits of the 16-bit data "n" are effective.

n
0 0 0 0 0 0 0 0
Upper 8 bits K0 to K255(H00 to HFF)
are invalid
When "n" is specified using K0, the contents of "D+1, D" and the special internal relay R9009 (carry flag) do
not change.
Precautions during programming
If the specified "n" is a multiple of 32 bits, the data will be the same as that before the operation.
e.g.,n = K32: same operation as n = K0
Flag conditions
・Error flag (R9007):
・Error flag (R9008):
・Carry flag (R9009): Content in the nth bit from MBS (most significant bit) turns on for an instant
