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.
– Jumper closed, non-isolated.
● Sampling time for digital inputs/outputs can be adjusted (p0799).
