5.203.3 Function 3: Evaluating rising and falling edges
C04000 = "2"
[5-152] Switching performance when evaluating rising and falling edges
Functional sequence
1. A signal change (FALSE-TRUE or TRUE-FALSE edge) at the input bIn sets the output bOut to TRUE.
2. After the time specified via C04001 the output bOut is reset to FALSE provided that no other si-
gnal change has taken place at the bIn input in the meantime.
• If another signal change takes place at the bIn input, the time C04001 restarts to elapse, i.e.
the output bOut is retriggerable.
