11.17 Free inputs/outputs

In a building automation and control system, the free I/Os can be used to interrogate
switch states, for example, or for direct switch control of another device over the
network. However, these functions are not suitable for time-critical processes (<1 s).
Free inputs can be defined as "open" or "closed" (see 11.2 ).
If not already in use, the following inputs and outputs can be used freely:
