3 Terms, definitions and conventions

3.1 Overview

It is assumed that basic concepts of OPC UA information modelling are understood in this specification. This specification will use these concepts to describe the Machinery – Result Transfer Information Model. 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 40001-1, as well as the following apply.

Note that OPC UA terms and terms defined in this specification are italicized in the specification.

3.2 OPC UA for Result Transfer terms

3.2.1 Configuration

3.2.2 Environment

The set of external entities working with the System in one way or another, e.g. PLC, MES, etc.

3.2.3 Job

The concrete implementation of a set of information that a machine needs to execute an order.
