13.6.1 Digital inputs/outputs
Signal processing using the digital inputs is shown in the function diagrams listed below.
Properties
● The digital inputs are "high active".
● An open input is interpreted as "low".
● Fixed debounce setting.
Delay time = 1 to 2 current controller cycles (p0115[0])
● Availability of the input signal for further interconnection.
–
Inverted and not inverted as a binector output
– As a connector output
● Simulation mode settable and parameterizable.
● Isolation block by block, set by jumper.
–
Jumper open: Isolated.
The digital inputs function only if a reference ground is connected.
– Jumper closed, non-isolated.
The reference potential of the digital inputs is the ground of the Control Unit.
● Sampling time for digital inputs/outputs can be adjusted (p0799).
