Example 2:
1. When X0.0 is switched from OFF to ON, the states of the sixteen bit devices starting from M0
are divided into groups (five bits as a group), and these groups are shifted to the left.
2. The shift of the states of the bit devices to the left during a scan is illustrated as follows.

Additional remark:
1. If S+n
2
-1 or D+n
1
-1 exceeds the device range, the instruction is not executed, SM0 is ON, and
the error code in SR0 is 16#2003.
2. If n
1
is less than 1, or if n
1
is larger than 1024, the instruction is not executed, SM0 is ON, and
the error code in SR0 is 16#200B.
3. If n
2
is less than 1, or if n
2
is larger than n
1
, the instruction is not executed, SM0 is ON, and the
error code in SR0 is 16#200B.
