Group 3.5: I/O Configuration

3.5.7.1 Digital inputs
Digital inputs are very flexible to use. Parameters are functions that are connected to the required digital
input terminal. The digital inputs are represented as, for example, DigIN Slot A.2, meaning the second
input on slot A.
It is also possible to connect the digital inputs to time channels which are also represented as terminals.
NOTE:
The status of digital inputs and the digital output can be monitored in the Multi-monitoring view,
see Chapter 3.4.1.
