For the purposes of this document, the terms and definitions given in [OPC 10000-1], [OPC 10000-3], [OPC 10000-4], [OPC 10000-5], [OPC 10000-7], [OPC 10000-8], and [OPC 10000-100] as well as the following apply.

a physical device which can be mounted on the Analyser or Analyser Channel to enhance its behaviour or operation.

NOTE: Examples of accessories are: vial holder, filter wheel, auger, and heater.

a physical location on the Analyser or Analyser Channel where an Accessory can be attached.

a device comprised of one or more analyser channels with a single address space which has its own configuration, status and control.

a subset of an Analyser that represents a specific sensing port and associated data, which includes scaled data (e.g. spectrum), configuration, status and control.

an OPC UA Client, which is aware of the ADI Information Model.

a set of values of all Parameters that when set, put the analyser in a well defined state.

a description of a mathematical process and associated information to convert raw data into scaled data.

an OPC UA Server, which implements the ADI Information Model.

one or more acquisitions using reference samples in order to determine the factors used to convert analyser raw data to scaled data.

a description of a mathematical process and associated information to convert scaled data into one or more process values (process data).

a defined series of hardware, valves, columns, and detectors, to produce an chromatographic result on a requested process stream analysis.

a specialization of Parameter defined in [OPC 10000-100] for AnalyserDevice, AnalyserChannel, AccessorySlot, Accessory or Stream and used to configure or publish information about the analytical device or its components.

NOTE: All Parameters described in this specification are represented by OPC UA Variables.

Data generated from scaled data by applying a chemometric model.

NOTE:Process data is typically represented as a scalar value or a set of scalar values and it is often used for process control. Examples of process data are: concentration, moisture and hardness.

Data generated by an analyser representing an actual measurement but without any meaningful units.

NOTE: Raw data is typically represented as an array of numbers. Examples of raw data are: raw spectrum, chromatogram and particle size beam count. Typically, this data is not directly consumed by a Client.

a physical interface point on the process where the process is monitored. Certain analysers perform in-place, non-destructive measurements whereas others extract a sample.

Data generated from raw data and representing an actual measurement expressed in meaningful units.

NOTE: Scaled data is typically represented as an array of numbers. Examples of scaled data are: absorbance, scatter intensity.

a mapping between an AnalyserChannel and the process sampling points.

NOTE: One AnalyserChannel can handle one or more sampling points, which means that an AnalyserChannel can be associated with one or more Streams.

one or more acquisitions using reference samples to demonstrate that the results provided by the analyser are still within the acceptable ranges.

Instances are referred to using the same identifiers as their type definition without Type suffix.

Identifiers described as a name enclosed in angle brackets e.g. <ParameterIdentifier> or <GroupIdentifier> represent identifiers assigned by the Analyser Server and not explicitly defined by this specification.
