For supported signals see Tab. 3.2.

5.2.2.5 Switch contact
Two discrete "dry contact" signals can be connected to each analog input (switches, buttons, relay contacts,
etc.).
Any resistors in the range 200…3000
Ω
can be used as shunt resistors. Both resistors on the input must
have the same nominal value.
Fig. 5.10 Switch contact wiring
The status of the input connected with two switch contacts is represented as an integer in the range 0…3
(Tab. 5.3).
