Rising Edge Each time a positive transition is detected at the input, the function block generates a positive pulse for one program cycle on the output. Signals Name I/O Type(s) Function P I BIT Input signal Q O BIT Output signal Comments A typical use case is the analysis of a status to catch a change.

Falling Edge Each time a negative transition is detected at the input, the function block generates a positive pulse for one program cycle. Signals Name I/O Type(s) Function P I BIT Input signal Q O BIT Output signal Comments A typical use case is the analysis of a status to catch a change.
