3.2 OPC UA for Textile Testing Devices terms
3.2.1 Textile testing device
Machine used to determine the properties of various materials in different production states, such as fibers, rovings, or yarns. It includes an integrated control system (e.g., PC, PLC) with an application for operating the device, defining test parameters, calculating results, evaluating statistics, and generating reports. The testing device incorporates interfaces for integration and automation purposes.
3.2.2 Manufacturing execution systems
Computerized systems used in manufacturing to track and document the transformation of raw materials into finished goods. These systems provide information that enables manufacturing decision-makers to understand how current conditions on the plant floor can be optimized to improve production output. The systems include interfaces for integration and automation.
3.2.3 Job
Set of instructions enabling the testing device to determine the properties of yarns and fibers. It includes a list of sample information (SampleInfo), carrier type identifier (CarrierTypeId), recipe identifier (RecipeId), and other relevant details. The number of tests required for each procedure in the recipe must be specified.
3.2.4 Recipe
Collection of test procedures and parameters that define a testing process for the testing device. The data structure of the recipe is outside the scope of this specification. Each recipe is identified by its unique RecipeId.
3.2.5 Test procedure
Process performed on a testing device to determine properties of materials such as fibers, rovings, and yarns. These procedures are often defined by national or international standards, such as ISO 13934 for tensile testing. Certain textile testing devices are designed to perform a single test procedure, while others can execute multiple procedures, either simultaneously or sequentially.
3.2.6 SampleInfo
Set of data required to associate results with a specific sample (SampleId) and to accurately parameterize test procedures based on sample properties, such as nominal linear density.
3.2.7 SampleId
Unique identifier associated with a produced package or sample, enabling its identification throughout an automated production environment.
3.2.8 JobId
Unique identifier created by the OPC client (e.g., manufacturing execution system, MES) for a job scheduled by the MES on a testing device.
3.2.9 Scheduled Job
Job created by the OPC client (e.g., manufacturing execution system, MES) with a unique JobId, transferred to the server using the “Store” or “StoreAndStart” method (see OPC 40001-3). Job metadata, including relevant testing conditions, are provided to the server as a job parameter. The results of this job are returned to the client and referenced by the SampleResultId.
3.2.10 Non-Scheduled Job
Job created manually on a textile testing device (TTD) without an order from the OPC client or manufacturing execution system (MES). The results of this test do not get a referenced JobId from the client but can still be transferred to the OPC client or MES. For the JobId a unique identifier is generated by the TTD.
3.2.11 TesterJobId
Internal identifier assigned by the testing device to a job, which is returned to the client (e.g., manufacturing execution system, MES) along with the test result. It allows tracking of a transferred result back to the data stored locally on the textile testing device.
3.2.12 Sample Result
Data transferred from the textile testing device (TTD) for each sample, containing information on measured material properties (e.g., elongation, maximum force). Each property is represented by a StatisticResultContent object within the ResultData. Results can be obtained either after completing a sample or after finishing the entire job.
3.2.13 TesterSampleResultId
Unique identifier created by the textile testing device for each sample result, potentially combining the TesterJobId and a sample identifier.
3.2.14 Sample
Material unit, such as a package of yarn or a batch of fibers, on which properties are determined by the testing device.
3.2.15 Testreport
Document, such as a PDF file, containing the results of a job as generated by the testing device. The specific content of the report is outside the scope of this specification.
3.2.16 Tester module
Optional hardware or software component of the textile testing device.
3.2.17 Operator
Laboratory staff responsible for operating the textile testing device.
3.2.18 CarrierTypeId
Reference to a type of carrier (geometric definition of a carrier or creel) stored on the textile testing device. The specific definition of the creel geometry is outside the scope of this specification.
3.2.19 Carrier / Creel
Device used to hold samples during testing, commonly utilized for transporting samples within the production area.
3.2.20 KPI
Key performance indicators providing information on the efficiency of a production environment, based on data such as machine running time, error frequency, and idle time.
