Group 3.5.1: Digital inputs
Digital inputs are very flexible to use. Parameters are
functions that are connected to the required digital
input terminal (see chapter User interfaces). 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.
The statuses of digital inputs and the
digital output can be monitored in the
Multi-monitoring view.
