Real-time Data Display program

Automatic Display of Lab Test Results
Testream/CS offers a unique capability to display test results (and, for production labs, associated product quality specifications) in real time by automatically updating an intranet-based web page published on the Testream/CS Lab Server. Any PC with a network connection to the Testream/CS Lab Server can browse these web pages and see the latest test data received from the Testream/CS Interface Application programs, as well as any other quality data sent directly to the Testream/CS Lab Server. These automatically updated web pages (no ‘refresh’ key required!) may be viewed using Microsoft Internet Explorer from a computer with a TCP/IP network connection to the Testream/CS Lab Server.

An Invaluable Tool
Testream/CS Real-time Display may be installed in any Testream/CS system configured with the Lab Tool Kit.
An invaluable tool for laboratory personnel, the Real-time Display:

• Visually confirms receipt of test results by the Testream/CS Lab Server—lab personnel will know ‘the data got there’ when they see it pop up on the Real-time Display.
• Provides ready access to complete test result detail, showing the individual data points as well as statistical summaries—no more ‘averages only’!
• Makes historical lab results as readily available as current lab results—testers can simply ‘scroll back in time’ to see their test results from preceding samples.
• Tells testers which tests need to be performed on each sample received in the lab.
• Offers direct access to the Data Editor if editing is required—if they see a ‘wrong’ result on the Display, they can quickly fix it on the spot.
• Alerts lab personnel to out-of-specification test results—sample IDs and test results are both highlighted for immediate review. Mill labs can define a number of different web pages, typically tailoring each to the unique data presentation requirements of the products pro duced. Segregating test data by production machine, the Real-time Display program creates web pages that become highly specific, targeted presentations of the latest quality results for each machine in the mill. Research labs might define web pages for each project being tested in the lab, which then function as project status displays.

Viewing Web Pages

The Testream/CS Home Page can be configured to display automatically when running a PC browser. Alternatively, Real-time Displays may be loaded as preferences in the browser (refer to your browser’s instructions for setting up preferences or “bookmarks”).

Real-time Displays present test result averages in the familiar spreadsheet presentation style. From the cell of a test result average, however, a single keystroke brings up the complete detail behind that average. You can see the individual test readings that went into the displayed average, along with statistical summaries including the standard deviation of acquired readings. Testing date and time, (optional) product specifications for tested property, and the full set of sample identifiers are also provided.

Web pages consist of two parts. The page’s “active” portion consists of the most current test data. (The number of samples that constitutes ‘most current’ is defined at system installation time and is usually a system-tuning parameter.) In this portion of the web page, new test data may be added, test data may be edited, detail data points may be viewed, and so on. All display commands may be issued against any samples appearing in the “active” portion.

New samples will eventually push previous samples beyond the page’s defined “active” portion. At that time, they simply become inactive, or ‘read only’, but continue to be available for viewing. This is a particularly helpful feature for production environments: with the Real-time Display, manufacturing personnel can quickly view lab results from previous production runs without leaving the current screen, and without bogging down the system’s response time. Historical data is now as easy—and as quick—to access as current data.

Navigating A Web Page
Each web page can contain up to 150 different test properties, which can be a lot of information to digest! The good news is that the Real-time Display program offers a wealth of single keystroke navigation tools to make it easy to move around a page. For example:

Type ‘O’ - to get a pop-up list of all out-of-specification test results for the selected sample. Click on the property of interest and the program auto matically takes you to that location on the page.

Type ‘J’ - to see a list of all tests appearing on the page. By clicking on the test(s) of interest, you can jump to that location.

Type ‘T’ - and (with the optional Product Specifications Entry & Maintenance program in place) get a list of all tests that remain to be performed on the selected sample. Work management will never be easier.

Changing Orientation
Web pages can present test data as vertical columns or horizontal rows. Simply click on the V/H toggle button to indicate your preference.

Real-time Display and QC Limits:Integration Features
The (optional) Testream/CS Specifications Entry and Maintenance program provides the tools to maintain a database of product specifications (QC limits). (Please refer to the Features Review section for this program for further details.) These specifications may appear in many places within Testream/CS—Interface Application programs, Data Extractor print reports, Real-time Display web pages—and cause a variety of system actions from color coding to font changes. Below is a summary of the Specifications Entry and Maintenance program elements that are integrated with the Real-time Display program:

• Specifications Display
  On each web page, you may toggle on/off a display of the QC limits that apply to the most recently posted sample on that web page. This might be helpful if you want to make more room on your display for test results: simply ‘hide’ the limits until you need to access them. You can also choose to display only a subset of your limits: process limits v/s customer specifications for example.
• Color Coding of Test Data Averages
  As test results averages are posted to a web page, they are compared against the QC limits in force for that sample. Test result averages are color coded according to the worst level of QC violation. Color coding of test results averages is designed to facilitate the rapid identification of out-of- specification test results.
• Color Coding of Sample IDs
  If any sample displayed on a web page has one or more test properties that tested out of specification, that sample’s ID is color-coded; a quick review of all sample ID colors easily identifies quality problems. Sample ID color coding in combination with the O command (see above) deliver direct, quick screen navigation to problem situations.
• Test Readings Compared to QC Limits
  The detailed data display available via the ‘D’ command (see next page), shows the QC limits for the selected test property. In addition, the indi vidual test data points are compared against limits and color-coded accordingly.
• Product Comments
  Two text documents entered into the Specifications Entry and Maintenance program—the Master Product Comment and the Revision Com ment—may be accessed via single key command (‘Q’) from a web page. These comment pages quickly become handy ‘notes’ for Quality Manage ment to use in advising production of particular quality issues, customer specific issues, prior run experiences, and so on.
• To Test Notifications
  Test frequency information stored in the Specifications Entry and Maintenance program is sent to a web page to advise lab personnel of properties they need to test for each new lab sample. Testers simply watch for the ‘T’ flags, and work to replace them with lab results.

Web Page Display Commands
From the web page display, you may issue a variety of single keystroke commands. As you will see, Testream/CS Real-time Display is simple to use, intuitive, and very direct. To get a pop up list of all key commands available, click on the ‘?’ button in the right corner of all web pages. The is a summary
of key commands:

• D (Detail)
  This command lets you see individual test readings that make up a displayed test result average. The detail pop-up box provides other information on the data points as well, such as the date and time of testing.
• E (Edit)
  If you see something ‘wrong’ on a web page, it’s easy to fix via direct access to the Lab Tool Kit Data Editor program. Simply position the cursor and type the letter ‘E’, and the Data Editor program is presented to you. This command prompts for a user ID and password before permitting user ac cess to the database record(s) to be edited.
• G (Graph)
  To see a landscape-style graph of test results averages for a particular property for all samples displayed on the web page, position the cursor on any cell for that test property and hit the “G” key. The quality limits currently in force (if any) for that property are displayed on the graph as scale markings. If there are no quality limits, the scale markings are set to 15% beyond the maximum, and 15% below the minimum, test result average.
• J (Jump List)
  To see a list of all tests appearing on the page. By clicking on the test(s) of interest, you can jump to that location.
• 0 (Out of Specification)
  To get a pop-up list of all out-of-specification test results for the selected sample. Click on the property of interest and the program automatically takes you to that location on the page.
• Q (QC Limits Comments)
  Text comment documents may be entered into the (optional) Testream/CS Specifications Entry and Maintenance program and may be viewed directly from a Real-time Display by hitting the “Q” key. Production personnel are now easily notified of prior run experiences, specific customer or production concerns, etc.
• T (To Test Flag)
  The (optional) Testream/CS Product Specifications Entry and Maintenance program lets you specify the desired testing frequency for each property and for each type of product made. When a new sample is posted to a web page, Testream/CS determines which properties need to be tested. The letter T is displayed in each test property cell to alert technicians of the testing required. To see a listing of tests that remain to be conducted on any particular sample, position the cursor in that sample’s row/column and hit the ‘T’ key.
• F (Flag Administration)
  In setting “To Test” notations based on the test frequency information in the (optional) Testream/CS Specifications Entry and Maintenance program, the Real-time Display program may fall out of sync with the actual production environment. To allow for this, the Real-time Display program pro vides, under password and user ID protection, the ability to override the system-generated “to test” flags that appear on a web page.
• ? (Help):
  Pressing this key or hitting the <?> button shows a menu of Real-time Display commands. You can use the arrow and enter keys or your mouse to .select a command. Press <ESC> if you don’t wish to execute any command.
