UAFX FxRoot

The FxRoot is the standard entry point for all instances related to OPC UA FX. It may contain multiple AutomationComponents that include Assets and FunctionalEntities. It may also contain, at most, one ConnectionManager.

NOTE   AutomationComponents are part of the Server (i.e., the Server exposes the AutomationComponents as instances). In the world of a physical controller, there would only be one instance of an AutomationComponent. In the world of digital twins, there might very well be multiple instances that represent each of the digitalized AutomationComponents – all running in one Server.
