Every NiagaraNetwork has a number of “Sys Def” components, both at the network level and at each child NiagaraStation level. Currently, there is no direct, standard, application for these “system definition” components—they exist mainly for use by NiagaraAX developers.

Sys Def facilitates an API interface to define the organization of stations in a Niagara system in a known hierarchy, and allows synchronization of basic information “up” that hierarchy. Developer usage may be especially useful in large “enterprise class” NiagaraAX installations that use “tiered” Supervisors.

At the time of this document, Sys Def components have no special Workbench views, apart from the standard set of views (property sheet, slot sheet, and so on).
