EDGE – Falling/rising edge detection in a binary signal

Block SymbolLicensing group: STANDARD

Function Description
The EDGE block detects rising (off $\to$ on), falling (on $\to$ off), or both edges on the input signal U, depending on the value of the iedge parameter. In case the desired edge (change in input signal) is found, the output Y is set to on for one step. As long as the value of the input signal remains unchanged, the output Y equals off. The output Y will also remain zero if the iedge parameter is set to detect a rising (falling) edge and a falling (rising) edge occurs in the signal.

This block propagates the signal quality. More information can be found in the 1.4 section.
