The Power of Context
In today’s manufacturing enterprises there exists a massive amount of underutilized data stored in process historians. The data is underutilized because its context has been lost, often a result of it being maintained in a person’s mind. In order for the next generation of manufacturing and information technology to provide its full promise data context must be integral to the data and be accessible and actionable by systems and algorithms.
The OPC Foundation’s Unified Architecture (OPC UA) provides an open method for creating and sharing industry specific data models with the ability to exchange information using well vetted communications protocols. OPC UA has been adopted by a number of different industry groups who have and are continuing to build industry specific information models that are starting to capture the contextual information associated with data. This presentation will explain the need for context, how OPC UA information models can be used to capture context and the work required to preserve context in open, interoperable and standards based formats.
