EDGE_ – Falling/rising edge detection in a binary signal

Block SymbolLicensing group: STANDARD

Function Description
The EDGE_ block detects rising (off $\to$ on) and/or falling (on $\to$ off) edges in the binary input signal U. The type of edges to detect is determined by the iedge parameter. As long as the input signal remains constant, the output Y is off. In the case when an edge corresponding with the iedge parameter is detected, the output Y is set to on for one sampling period.

Input

U	Logical input of the block	Bool

Output

Y	Logical output of the block	Bool

Parameter

iedge

Type of edges to detect $⊙$ 1

Long (I32)

1 ....: Rising edge
2 ....: Falling edge
3 ....: Both edges
