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
Ensures that a recipe produces the same result on different entities of my machine. The configuration can optionally be used to make a program/recipe usable for different articles. The characteristics are often technology or industry specific.
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.
3.2.3.1 Untitled
3.2.4 Part
Describes a concrete instance or instances of the Product (e.g., a specific DIN A4 sheet).
3.2.4.1 Untitled
3.2.5 Program
Contains a number of executable activities for controllable units.
3.2.5.1 Untitled
3.2.6 Product
Describes the output that is to become the core of the value creation (e.g. DIN A4 sheet).
3.2.6.1 Untitled
3.2.7 Recipe
The set of information required to uniquely describe the production requirements for one or more specific products.
3.2.7.1 Untitled
3.2.8 System
Any complex information processing system generating results.
3.2.9 System-wide unique
At any given time no other entity of the same type and meaning shall exist in the OPC UA Server with the same value.
3.2.9.1 Untitled
3.2.10 Step
A domain- or manufacturer-specific definition that represents an intermediate stage of the job process.
