PrIO
PrIOs are programmable terminals, each independently configurable as an input or output.
See 4.7 Connecting inputs and 4.8.3 PrIO configured as output for connection details.

Connecting inputs
The type of input is determined by the way in which the detectors are physically connected. The type of
each input is then specified in the programming. In this way you can create a system that includes inputs
of different types.
The input specialisation is defined exclusively by programming.
