The OPC UA companion specification for Analyser Devices (ADI) defines a data model for process and laboratory analysers. It allows integrating analysers into the supervisory control and tracing systems seamlessly. This Information Model is also referred to as the ADI Information Model. The model is intended to provide a unified view of analyzers irrespective of the underlying device. Reduction of the maintenance cost is a value of this approach, because any replacement of the analysers has very limited impact on the upper systems – it is a “plug and play” solution. Analyzers can be further refined into various groups, but the specification is generic and defines the ADI Model that can be applied to all the groups of analyzers. ADI is based on OPC UA for Devices (DI).

ADI Capabilities

Analyzer Device Model


Discovery ID: ADI

Understand and support the OPC UA for AnalyzerDevices base Information Model.
This includes Methods for configuration, the states and transitions

Usage Considerations
Determine the process state/behaviour by measuring selected physical values that are characteristic for it. The measurement results are process data that can be used to control, trace and optimize the production process.
