6.1.2 FALLING PULSE (NON)
Use in a sequence program Possible
Use in a motion program Not possible
J Overview
FALLING PULSE (NON) is ON during one scan of bit output when the bit input status changes
from ON to OFF. The register that stores the previous bit output value is used as a work of NON
processing. Set the registers that are not used for other processes.

Description
The NON command is designated as follows:
DB000002=NON(DB000000) DB000001);
