Explanation:
1. The data in the n
1
and these groups are shifted to the right. The data in the n
shifted to the devices starting from D to fill the vacancy.
2. Generally, the pulse instruction WSFRP is used.
3. The operand n should be within the range between 1 and 512. The operand n
1
within the range between 1 and n
Example 1:
1. When X0.0 is switched from OFF to ON, the data in the sixteen word devices starting from D20
is divided into groups (four 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.
