Product Overview

NWA QAx is used to deliver graphical SPC output to end users by easily embedding SPC within other software applications

NWA QAx is a complete SPC software development tool kit. It allows you to embed ActiveX-based SPC technology into your application and supply a user interface that matches your users' needs and the rest of your application's look-and-feel. The NWA QAx controls provide statistical results, graphics displays, and lists of alarms and exceptions. The graphical display supports click-events to display drill-down information for each point, such as date/time stamp, lot, or batch number.

Alarms and exceptions can be defined based on violations of control limits, specifications, pattern rules (such as the Western Electric and Westgard Rules), or fixed limits. These are returned to the application in real time, providing the support needed to drive alarm displays and produce exception reports. NWA QAx can be used for SPC applications ranging from graphical displays of SPC charts to behind-the-scenes process monitoring.

Compatible with NWA Quality Analyst

Applications using NWA QAx also integrate seamlessly with NWA Quality Analyst, simplifying your SPC solution design and reducing development time and support requirements. Your application can be designed to meet the more basic needs of typical users, while those who require more sophisticated analytical capabilities can use the full capabilities of NWA Quality Analyst.

Comprehensive, Yet Easy to Implement

NWA QAx is a well-established ActiveX solution with several years of use in SCADA, LIMS and MES applications. NWA QAx is both comprehensive and easy to implement. Basic SPC charts can be added to your application with a few lines of code, while hundreds of methods and properties are available to support the most complex requirements. Flexible data methods make it easy to populate and manage Data Sets of up to 200 variables, while a "validate" method checks to ensure correct use of the configuration properties before execution.
