Explanation
1. When the value in the accumulative register switches from 0 to 1, the NP instruction keeps the value 1 in the
accumulative register for a scan cycle. After the second scan cycle is finished, the value in the accumulative register
changes to 0.
2. Use the FB_NP instruction in function blocks.
