Additional remarks
1. When this instruction is executed, a cycle time that is too long or a too short causes the state of the switches to be
read incorrectly. Use the following tips to solve this issue.

When the scan cycle is too short, the I/O may not be able to respond in time and the correct states of the
inputs cannot be read. You can set a fixed scan time to solve this issue.

When the scan cycle is too long, the switch may be slow to react. You can write this instruction in a timer
interrupt task to set a fixed time to execute this instruction.
2. If S+7, D +n-1, or D

code in SR0 is 16#2003.
3. If n is not between 2–8, the instruction is not executed, SM0 is ON, and the error code in SR0 is 16#200B.
4. If you declare the operand S in ISPSoft, the data type is ARRAY [8] of BOOL.
