This document specifies an OPC UA Information Model for the representation of textile testing devices. The companion specification “OPC UA for Textile Testing Devices” aims for a straightforward integration of different kinds of textile testing devices into MES and other IT systems. The purpose of OPC UA Information Model is to describe the information that is transferred from and to testing instruments for fibres and yarns, e.g. in the spinning industry, in research institutes, quality control laboratories or for production control in industrial environments.
The target of this specification is to provide a standardized interface for textile testing devices from different manufacturers to ensure compatibility. Online testing devices are not within the scope of this companion specification.
The following functionalities for a textile testing device are covered:
- General information about the textile testing device (e.g.: identification parameters)
- Current configuration and status of the textile testing device
- Recipe management (transfer of recipes (testconditions and instructions) to/from the testing device)
- Result management (transfer of the generated test results to the MES or other IT-systems)
- Job management (information about the jobs running on the device and methods to interact)
- KPI and statistics
- Logbook of relevant changes on the machine
- Maintenance, events and notifications for upcoming user interactions and error handling on the testing device
