Quality AnalytiX Quick Start Guide

Configuring SPC Tags in Hyper Historian (Classic)

  1. Open an active Hyper Historian (Classic) database and expand the folder called SPCDistribution Rules. This folder includes the default set of rule sets in Quality AnalytiX. Each rule set defines the tendencies your SPC tag values should or should not follow. For more information about creating or editing SPC distribution rule sets, see the SPC Distribution Rule Sets topic.

  2. In Hyper Historian, expand the Data Collections folder and create a new folder called SPC. Once you have created this folder, right-click on it and select the + SPC Tag option to create a new SPC tag. The SPC Tag Configuration Dialog appears, and the project explorer contains the SPC folder and your new tag, as shown below:

    4. Select a Collection Type of XBarS to summarize the sample values that this SPC tag measures.

    5. In the Chart Properties area of the tab, set the limits of the XBar summary statistic to 110.00 (for a Hi Limit) and -10.00 (for a Lo Limit). Similarly, set the limits of the StdDev summary statistic to 10.00 (for a Hi Limit) and 1.00 (for a Lo Limit).

    6. Move to the "Control Limits" tab of the dialog. In the Calculated Limits area of the tab, set the XBar values to 90 for UCL, 50 for CL, and 10 for LCL. Set the StdDev values to 8 for UCL, 4 for CL, and 2 for LCL. The following image shows the completed configuration on this tab.

Using SPC Data in GridWorX64 Viewer

Quality AnalytiX is a Statistical Process Control solution which is flexible enough to apply to any quality monitoring application, yet simple to configure and deploy. It offers an extensive set of SPC calculations, control charts, portal dashboards, and standard quality reports that can be applied in a variety of combinations to help pinpoint quality or production issues. When combined with GENESIS64 it can also generate an alarm in case of rules violation.

The following shows how to view data which was processed by the Quality AnalytiX engine. You can view the data in form of:

  • GridWorX64 Viewer charts

  • Process points

  • ReportWorX Express reports

  • GenEvent Server messages in an AlarmWorX64 Viewer

GridWorX64 Viewer allows you to analyze the SPC data in the form of histograms or control charts that highlight samples which violate rules and provide tooltips to explain the violations. Tooltips of the samples show the alarm message for the violations.
