Short Description
In terms of information access, there is an overview of information models in OPC UA Information Models.
OPC UA Companion Specifications are information models that are not developed by the OPC Foundation but by experts in the domain of the model. These models are published and distributed via the OPC Foundation.
To ensure the information models follow similar principles and don't duplicate information, there is the [[OPC Foundation Harmonization Group]
VDMA 40001 - OPC UA for Machinery is a companion specification that can be used as a basis of more specific domain models. It contains building blocks that are useful across domains.
The following topics are special models within OPC UA, in the case of FX they span both the base functionalities and the information models: - OPC UA FX (Field eXchange) - OPC 10000-110 - OPC UA for Asset Management Basics
The OPC 30400-1+2 - OPC UA for Cloud Library is a repository of information models, especially when used in conjunction with cloud infrastructures.
