Explanation
1. This instruction shifts the data in the n registers starting from D to the right, and clears the data in D+n-1 to 0.
2. In general, the NSFRP pulse instruction is used.
3. For 16-bit instruction, the value in the operand n must be between 1–512. For 32-bit instruction, the value in the
operand n must be between 1–256. For the application of 32-bit instruction, you need to use ISPSoft V3.09.07 or
later and AS PLC CPU FW V1.08 or later.
Example 1
When M0 switches from OFF to ON, the instruction shifts the data in D1–D6 to the right, and clears the data in D6 to 0.
