Falling Edge
easy
Produces a single-scan pulse on every 1-to-0 transition of a BOOL input.
What it teaches
Mirror of rising-edge detection — fire when the signal turns off instead of on. The key insight: a falling edge is just the rising edge of the inverted signal, so whatever you built for rising-edge works here flipped.
Parameters
| Tag | Direction | Type | Default | Description |
|---|---|---|---|---|
| In_Signal | Input | BOOL | 0 | Input signal to monitor |
| Out_Pulse | Output | BOOL | 0 | Pulses high for one scan on falling edge |
Required behavior
- Out_Pulse is 1 for exactly one scan when In_Signal transitions from 1 to 0.
- Out_Pulse is 0 at all other times.
