umati showcase information model for Machine Tools

In the following the umati showcase describes the additional information on top of the OPC 40501-1 UA for MachineTools companion specification.

Please refer to the provided XML-NodeSets, UaModeler-project or the Sample Server for exemplary implementation.

NodeSets

Normative NodeSet hosted by the OPC Foundation

For umati Machine Tool partners

UaModeler Project as a quick start ( Remark: You have to be an umati partner and added to the access list. (Contact: info@umati.org)

General information valid for the umati showcase demonstration

DISCLAIMER

For all applications the OPC UA server is to be configured without predefined NodeIds for the instances. Clients need to utilize the Services Browse and TranslateBrowsePathsToNodeIds to access nodes of interest.

Identification data

The identification for Machine Tools are inherited from the Machinery companion specification. To fill the demo dashboard machine page with the most content the variables marked with a strong mandatory should be provided if you like to look the machine identification nicely.

Special requirements for correct location of the machine icon on the dashboard

The instance Location property is evaluated according to the special requirements detailed here to place a map icon for the machine.

Adaption of the provided information models for your purpose

• The provided NodeSet contains the address space with the ObjectTypes, VariableTypes and DataTypes of the MachineTools companion specification and must not be changed.

• Change the URI of the instance namespace (optional, but recommended)

  http://www.<MANUFACTURERDOMAIN>/example

• The rules for creating a URI can be found online. Please follow this link. In the case of a URL as a URI, it is not necessary that the site actually exists, it only identifies the machine uniquely. In order to simplify debugging it is recommended to choose a URI which allows an identification of the machine also for third persons, e.g. by including the company name.

• The machine will get a unique NamespaceURI after being integrated to the datahub by addition of a suffix to ensure unique namespaces.

Machine Tool - Overview

Active Program Statusbar

For the status overview in the dashboard, the StateNumber of the ProductionActiveProgramType.State.CurrentState.Number is stored and plotted over time. The status bar does NOT relate to the stacklight status!

Each status is assigned to a color, the color scheme is here (subject to change):

State	Number	Color
Initializing	0	⚪ Grey
Running	1	🟢 Green
Ended	2	🔵 Cyan
Interrupted	3	🟠 Orange
Aborted	4	🔴 Red
Any other (unspecified) state		⚫ Black

A gap is left for periods of time in which no data was recorded (e.g. machine offline). An exemplary timeline is shown above.
