YASKAWA VIPA SPEED7 - Edge-Triggered Instructions

3.10 Edge-triggered instructions
Detection of an edge change. The current signal state of the RLO is compared with the
signal state of the instruction or edge bit memory.
FP detects a change in the RLO from "0" to "1"
FN detects a change in the RLO from "1" to "0"
