13.3.2.1 Overview

13.3.2.2 Facets

13.3.2.2.1 Basic Vision System Server Facet

This facet defines the elements for a very basic machine vision system. It shall implement the mandatory nodes and also some fundamental types and functionality concerning results, configurations and recipes

13.3.2.2.2 Inline Vision System Server Facet

An “inline” machine vision system, as defined in Section 3.1, is used in the manner of a 100% inspection system within a production line (which does not necessarily mean that it is a quality inspection system at all).

This type of use typically takes place under the guidance and supervision of a control system which requires information about the current operating state of the vision system, error conditions and other diagnostic information, and may want to inform the vision system about safety-related events.

13.3.2.2.3 Automatic Mode Server Facet

This facet gives a superior control system more detailed control over the behavior of the vision system. This is related to the notion of an inline machine vision system which will typically operate in automatic mode.

13.3.2.2.4 Processing Times Server Facet

This facet contains information about the basic start and end time of jobs as well as information about internal timing of jobs.

13.3.2.2.5 File Transfer Server Facet

This facet combines the various TemporaryFileTransfer definitions for the transfer of black-box data to and from the vision system.

13.3.2.2.6 Basic Result Handling Server Facet

This facet contains the basic definitions for the handling of result content within the ResultDataType (the basic definitions for the identification of results are already contained in the Basic Vision System Facet in Section 13.3.2.2.1).

13.3.2.2.7 Inline Result Handling Server Facet

This facet contains result handling functionality which will typically be expected from an inline vision system (see Section 13.3.2.2.2). Since such a system running within an automated production line will usually handle series of individual, often identifiable parts, and may need to buffer results for later collection, the conformance units Part ID and Result File are part of this facet.

13.3.2.2.8 Full Result Handling Server Facet

This facet adds the capability of exposing individual results in the address space inside the Results folder to the Inline Result Handling Facet (see Section 13.3.2.2.7).

13.3.2.2.9 Standard Configuration Handling Server Facet

This facet combines the handling of configuration identification with the transfer of black-box configuration content by TemporaryFileTransfer objects.

13.3.2.2.10 Full Configuration Handling Server Facet

This facet adds the capability of exposing individual configurations in the address space inside the Configurations folder to the Standard Configuration Handling Facet (see Section 13.3.2.2.9).

13.3.2.2.11 Standard Recipe Handling Server Facet

This facet combines the handling of recipe and product identification with the transfer of black-box recipe content by TemporaryFileTransfer objects.

13.3.2.2.12 Full Recipe Handling Server Facet

This facet adds the capability of exposing individual recipes and products in the address space inside the Recipes and Products folders to the Standard Recipe Handling Facet (see Section13.3.2.2.1113.3.2.2.11).

13.3.2.3 Profiles

13.3.2.3.1 Basic Vision System Server Profile

This Profile is a FullFeatured Profile intended for basic machine vision systems capable of limited handling of recipe and configuration information, provision of result information and content and executing the standard automatic mode as defined in Section 8.3.

It is built upon the Embedded 2017 UA Server Profile which provides Security conformance units.

13.3.2.3.2 Basic Vision System Server Profile without OPC UA Security

This profile is intended as fallback for very limited systems not capable of implementing OPC UA security functionality as required by the Embedded 2017 UA Server Profile used in all other profiles in this specification. We strongly recommend implementing OPC UA security whenever possible.

13.3.2.3.3 Simple Inline Vision System Server Profile

In accordance with the notion of an “inline” machine vision system, used, as defined in Section 3.1 and Section 13.3.2.2.2, in the manner of a 100% inspection system within a production line, this is a FullFeatured Profile, providing the typical functionality required for a simple version of such a system: full automatic mode, diagnostic info required by a control system, basic result handling. It lacks the handling of client-supplied IDs included in the (not-simple) Inline Result Handling Facet in Section 13.3.2.2.7, leaving the part tracing to the superior control system.

13.3.2.3.4 Simple Inline Vision System with File Transfer Profile

This FullFeatured Profile complements the Simple Inline Vision System with the handling of recipe and configuration identification and the black-box transfer of contents by TemporaryFileTransfer objects.

13.3.2.3.5 Simple Inline Vision System with File Revisioning Server Profile

This FullFeatured Profile complements the Simple Inline Vision System with File Transfer by the capability of managing recipe and configuration versions.

13.3.2.3.6 Inline Vision System with File Transfer Server Profile

This FullFeatured Profile complements the Simple Inline Vision System with File Transfer by the complete ProcessingTimes information and the additional capability of handling result content and client-supplied IDs defined in the Inline Result Handling Facet in Section 13.3.2.2.7, and is thus suitable for sophisticated vision systems in automated production handling part traceability information.

13.3.2.3.7 Inline Vision System with File Revisioning Server Profile

This FullFeatured Profile complements complements the Inline Vision System with File Transfer by the capability of managing recipe and configuration versions and is thus suitable for sophisticated vision systems in automated production handling a multitude of recipes and configurations changing over time.

13.3.2.3.8 Full Vision System Server Profile

This FullFeatured Profile comprises the complete functionality of this specification and is thus suitable for the most complex vision systems.
