Example 2:
1. When X0.0 is switched from OFF to ON, the data in the sixteen word devices starting from D20
is divided into groups (five words as a group), and these groups are shifted to the right.
2. The shift of the data in the word devices to the right during a scan is illustrated as follows.

Additional remark:
1. If S+n -1 or D+n -1 exceeds the device range, the instruction is not executed, SM0 is ON, and
