Figure 12-9 Digital inputs: signal processing using DI 0 of CU320 as an example

Properties

●The digital inputs are "high active".

●An open input is interpreted as "low".

●Fixed debouncing 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.

●CU320: Isolation block by block, set by jumper.

–Jumper open: electrically isolated.

The digital inputs function only if a reference ground is connected.

–Jumper closed, non-floating.

The reference potential of the digital inputs is the ground of the Control Unit.

●Sampling time for digital inputs/outputs adjustable on CU320 (p0799)
