| ## Description |
| |
| Observes a boolean value and forwards the event when a signal edge is detected |
| |
| *** |
| |
| ## Required input |
| |
| ### Boolean Field |
| Boolean field that is observed |
| |
| *** |
| |
| ## Configuration |
| ### Kind of edge |
| * Detect rising edges |
| * Detect falling edges |
| * Detect both |
| |
| ### Delay |
| Defines for how many events the signal must be stable before result is emitted. |
| (E.g. if set to 2, the result is not emitted if value toggles between true and false, |
| it fires when two consecutive events are detected after the flank) |
| |
| ## Output |
| Emits input event, when the signal edge is detected |
