Essentially, Ndio 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 Ndio proxy points, which reside under an NdioBoard “device”, which in turn resides under an NdioNetwork container in the station’s DriverContainer (Drivers).

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

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

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