17.1.165.3 Function 2: Evaluate rising and falling signal edges
[17-78] Switching performance for function selection "2: High and low edge"
Functional sequence
1. A signal change (FALSE/TRUE edge or TRUE/FALSE edge) at the
bIn
input sets the
bOut
output to
TRUE.
2. After the parameterised pulse duration has elapsed, the
bOut
output is reset to FALSE unless
another signal change has taken place at the
bIn
input.
• In case of another signal change at the input
bIn
, the pulse time restarts to elapse, i.e. the
output
bOut
can be retriggered.
