4.13.8.13.3 Digital inputs
Unfiltered
The input state is collected with a fixed offset to the network cycle and transferred in the same cycle.
Filtered
The filtered status is collected with a fixed offset to the network cycle and transferred in the same cycle. Filtering
takes place asynchronously to the network in multiples of 200 µs with a network-related jitter of up to 50 µs.
4.13.8.13.3.1 Digital input filter
Name:
ConfigOutput02
This register can be used to specify the filter value for all digital inputs.
The filter value can be configured in steps of 100 μs. It makes sense to enter values in steps of 2, however, since
the input signals are sampled every 200 μs.

4.13.8.13.3.2 Input status of digital inputs 1 to 4
Name:
DigitalInput or
DigitalInput01 to DigitalInput04
StateDigitalInput01 to StateDigitalInput04
The input status and status of digital inputs 1 to 4 are mapped in this register.
Function model 0 - Standard only:
The "packed inputs" setting in the AS I/O configuration is used to determine whether all of this register's bits
should be set up individually as data points in the AS I/O mapping ("DigitalInput01" through "DigitalInput04" and
"StateDigitalInput01" through "StateDigitalInput04") or whether this register should be displayed as an individual
USINT data point ("DigitalInput").
