3.5.7.1 Digital inputs
Digital inputs are very flexible to use. Parameters are functions that are connected to the re-
quired digital input terminal. The digital inputs are represented as, for example, DigIN Slot A.2,
meaning the second input on slot A.
It's also possible to connect the digital inputs to time channels which are also represented as
terminals.
