 When M, Y, S are assigned to serve as the bit operand, only K4 (16-bit)
and K8 (32-bit) are effective, e.g. K4M0, K8Y0.
 Command Motion Explanation
Ϩʳ When X0 goes from OFFШON, the 16 bit data of D10, along with the
attached carrying flag (M1022), will rotate 4 bits to the left, as shown in
the diagram, and b12 that located at D10 originally will then be moved
to the carrying flag M1022, and that the original contents of the
carrying flag M1022 will be moved to the bit of b3.

Ϩʳ Please Notice: If use the pulse wave contact to drive this command, X0
will shift

bits to the right when X0 is in the rising-edge. If use the
normal On contact to drive this command, the bit shifting operation will
occur every time during every scan.
