16.1.44.1 Function 0: Evaluate rising signal edges
[16-24] Switching performance for function selection "0: High edge"
Functional sequence
1. A FALSE-TRUE 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 FALSE/TRUE edge has been set at the
bIn
input.
– If an additional FALSE-TRUE edge occurs at the
bIn
input, the pulse duration starts
again from the beginning, i.e. the
bOut
output can be retriggered.
16.1.44.2 Function 1: Evaluate falling signal edges
[16-25] Switching performance for function selection "1: Low edge"
Functional sequence
1. A TRUE-FALSE edge at the
bIn
inputs sets the
bOut
output to TRUE.
2. After the parameterised pulse duration has elapsed, the
bOut
output is reset to FALSE
unless another TRUE/FALSE edge has been set at the
bIn
input.
– If an additional TRUE-FALSE edge occurs at the
bIn
input, the pulse duration starts
again from the beginning, i.e. the
bOut
output can be retriggered.
