Essentially, Nrio uses the standard NiagaraAX network architecture. See “About Network architecture” in the Drivers Guide for more details. For example, real-time data is modeled using Nrio proxy points, which reside under an NrioModule “device”, which in turn resides under an Nrio network container (M2mIoNetwork or NrioNetwork) in the station’s DriverContainer (Drivers).

Hierarchically, the component architecture is: network, module, points extension, points (Figure 1).

Unlike most other drivers, points is the only extension under an NrioModule “device,” and the sole purpose of the Nrio driver—to configure (and proxy) the actual Nrio I/O hardware points.

You use “Manager” views of Nrio container components to add all Nrio components to your station, including Nrio proxy points. In these views, the Nrio driver provides online “discovery” of available hardware (Learn Mode), which greatly simplifies engineering.
