Currently, by default every NiagaraAX station has a Niagara Network under its Drivers container. The Niagara Network is where data is modeled that originates from other stations. Generally, this is done using the same driver architecture used by other (non-Niagara) drivers. See About Network architecture.
A Niagara Network has the following unique differences:
-
All proxy points under a NiagaraStation are “read only” types, namely one of the following:
-
BooleanPoint
-
EnumPoint
-
NumericPoint
-
StringPoint
However, note that a Niagara proxy point inherits any actions from the originating (remote) point or object. For more details, see Niagara proxy point notes.

Connections between stations occur as client and server sessions using the Fox protocol. The requesting station is the client, and target (responding) station is the server. A Workbench connection to a station operates identically, where Workbench is the client, and station is server. Client authentication (performed by the server) is required in all Fox connections.
Starting in AX-3.7, the Fox protocol can run over an SSL encrypted connection following certificate-based server authentication.
This secure Fox SSL (or Foxs) is noted and mentioned in various subsections of this document update. For complete details,
refer to the NiagaraAX SSL Connectivity Guide.
