DriveTest Findings Webinterface

Introduction

The purpose of the DriveTest Webinterface is to manage test specific configurations. It also offers tools for production analysis and statistics. A user management ensures traceability. It can be accessed from every PC in the same network via following address structure:

 http://ip-address/Findings 

or

 http://PC-Name/Findings 

Note: The Webservice is optimized for Google Chrome. Functions may not work properly on other browsers or Internet Explorer below version 11.

Result Browser

Purpose

The Result Browser shows all DUTs and its test results together with additional information about the individual test. Every column can be used to sort the list by clicking the arrows above.

Step Result Properties

Some test steps generate additional properties. The following steps can contain these additional properties:

  • PassFailTest
  • NumericLimitTest
  • MultipleNumericLimitTest
  • StringValueTest

Additional properties can be:

  • Read value
  • Compare value
  • Text message in case of failed test step
  • Additional information (depends on test)

Filter Options

Several filters can be applied to have a look at specific DUTs. All filters can be used simultaneously. Filters are applied after clicking the button “Apply filter”.

  • Station: Shows all DUTs of only one test stand. The station names mirror the TestStand Station-IDs.
  • Type: Select only one type of DUT.
  • Status: Filters the DUTs according to their final result. Possible statuses are “Passed”, “Failed”, “Error” or “Terminated”.
  • Time Frame: Time-based filters.
  • Serial: Helps to find a DUT by reference to its serial number or part of a serial number.

Time Frame


Here it is possible to define a time frame which limits the results again. Filters can be set with the help of predefined time frames on the left side. User defined time filters are possible by selecting a range in the calendar view. Filters are active after clicking “Apply”.

Export Options

Export enables the data to be used in other applications or to be printed.

  • Export to CSV: Creates a CSV-file to be opened in Microsoft Excel

Dashboard

The Findings Dashboard section gives a long-term overview of the production output. Different charts show either the trend of specific tests or simply pass/fail results. Filters can be applied through Stations, Type and/or a time interval. All charts and tables can be exported.

Performance

Results

Shows an overview of test results in the given time frame in a pie chart. The chart is divided in the types and these however are divided in their individual results.

Failures

There is a second pie chart which shows an overview of the DUT failures. The chart is divided in the DUT types and these however are divided in their individual failures.

UUT Results

Shows different charts to have an overview of the production output. A click on an area of the chart leads to the Result Browser with set filters accordingly.

Absolute UUT Result Chart

Each bar shows the total amount of UUTs tested on one day. They are also separated in passed, failed, erroneous and terminated tests. Results can be hidden by clicking its colour below the graph.

Percentage UUT Result Chart

This chart shows the test results of each day by percentage. 100% are all UUTs tested on one day. The amount of passed, failed, erroneous and terminated tests are shown as fractional parts.

The table at the end shows the number of passed, failed, erroneous and terminated tests as well as UUTs tested in total.

Test Time

Shows the total time of single test runs in the set time frame. A filter to show only passed UUTs can be set.

UUT Retests

Shows the number of retested and then passed UUTs and the ones tested with first time pass. All UUTs with the same serial number are automatically detected as retests. The list below shows all retested DUTs and how often they were retested.

Failed Steps per Day

This chart shows the number of failed test steps for each day. Tests with the highest failure rate can be easily examined. Unimportant tests can be hidden by clicking its colour under the chart. The table below can be used to search for desired failed tests. By that it is easy to create a list of serial numbers of all UUTs with this particular failed step.

Numeric Results

Numeric Limit Tests in NI TestStand are used to check if a numeric value is equal, lower, higher or between certain limits. All numeric limit tests used in a test sequence appear in the list above the chart. The green bar represents the lower and higher limit of the test. The blue dots are the actual measured values.

Additional information is shown by pointing on the blue dots.

Quicklist


The Quicklist gives a quick overview about stored UUT parameters. Next to basic information about the test date, overall result and UUT identifications, read parameters from the UUT during the test are summarized.
Example:

Administration


In the Administration section test parameters can be changed, there are database configuration options and the user management. Every change of parameters is recorded in the Event Log. The tab “Administration” only appears for logged in and eligible users.

Login


To get access to the Administration section a login is necessary. Not all users have access to all settings. This depends on the role of the active user. For more information about roles see chapter User Management. After 2 minutes inactivity the user gets logged out automatically.

Testsystem Configuration


Configurations are separated in “Project”, “Station”, “Device” and “Config-Group”. Typical Config-Groups are “Basic”, “Anti Pinch”, “Drive_Versions” or “Motion Lab”. The content of each configuration is listed in a table view. A configuration table can be exported using the export options or as a complete database backup.

Column Name Explanation Example Value
Edit Edit the item -
Delete Delete the item -
Key Name of the configuration result_directory
Value Current value of the configuration C:\Users\Public\Documents\DriveTest\C217
Description Short text to describe the meaning of the configuration -

All changes will be logged and can be viewed in the Event Log.
Note: This section is only available for administrator, technician and operator users.

Database Settings


Gives the opportunity to backup, restore and reset several DriveTest databases. This section is only available for administrative users.

Test Data Storage Time

This option allows to automatically delete production result data after a specific amount of days. Once set the data will be cleaned prior to the selected days. No backup will be created. This function can be used if local storage is limited or the data is simply not needed anymore. Set to “0” for unlimited data storage. This function is independently available for noise data storage time.

Note: The data will be deleted every 24h at the time the function was activated. It is limited to 10.000 data sets per execution to avoid blocking the system. If more than 10.000 data sets have to be deleted the function will proceed after 24h.

User Management


In this section users can be managed or new ones added. All users are listed in a table view. There are some default users:

User Name Password
Administrator admin
webasto -

Additionally there are DriveTest internal users to ensure DriveTest has always administrator access. \\Note: This section is only available for administrator and technician users.
