What is new for TestStand 3.1?
The following list describes the new features in TestStand 3.1 and other changes since TestStand 3.0.
Flow Control Step Types
TestStand 3.1 introduces the Flow Control step types. You can use the following new step types to implement common programming constructs:
Synchronization Step Types
TestStand 3.1 introduces new step types for the automatic scheduling of steps that require access to resources (for example, hardware resources). The new step types are as follows:
Refer to the AutoSchedule.seq file, located in <TestStand>\Examples\Auto Schedule, for an example of how to implement auto scheduling in a sequence. This example demonstrates how the Auto Schedule step type can improve performance when testing multiple UUTs in parallel using shared hardware resources. You can use the Auto Schedule step to dynamically determine the order in which a UUT uses its required resources in order to minimize delays that occur while the UUT waits for a resource to become available.
LabVIEW Express VI Instantiation
TestStand 3.1 adds the ability to directly specify and configure an Express VI to call from a TestStand sequence.
The Edit LabVIEW VI Call dialog box contains a new combo box in which you can select which type of VI to call. If you select Express VI from the combo box, the Browse button displays the LabVIEW icon instead of the open file icon. Click the LabVIEW icon to open a context menu which displays all of the Express VIs in the currently selected LabVIEW function palette.
Note You can only configure calls to Express VIs when the LabVIEW Adapter is configured to use the LabVIEW Development System. If you configure the LabVIEW Adapter to use the LabVIEW Run-Time Engine, you will not be able to select and configure an Express VI. Additionally, your active LabVIEW Development System must be version 7.1 or later to use Express VIs.
Enhanced LabVIEW and LabVIEW Real-Time Integration
LabVIEW Utility Step Types
TestStand 3.1 introduces new step types for communicating with LabVIEW remote systems. The new step types are as follows:
LabVIEW Real-Time Error Messaging
TestStand 3.1 also improves the error messaging for LabVIEW Real-Time. The following error cases now contain more descriptive error messages:
FTP Files Step Type
TestStand 3.1 introduces the new FTP Files built-in step type. This step type gives you the ability to download files to and upload files from remote systems. This step type is particularly useful if you are using a LabVIEW Real-Time system.
CheckBox User Interface (UI) Control
TestStand 3.1 introduces the CheckBox control. Connect an Application Manager, SequenceFileView Manager, or ExecutionView Manager control to the CheckBox control to connect to commands that you can toggle.
TestStand 3.1 includes the following improvements to the Property Loader:
ExpressionEdit Control Enhancements
In TestStand 3.1, the ExpressionEdit control contains the following new features:
User-Defined Location for Configuration Files
TestStand 3.1 introduces the ability to modify the location of the TestStand configuration file directory. By default, the directory is <TestStand>\Cfg. This new capability allows users who do not have write access to the TestStand installation directory to run TestStand. You can specify the configuration file directory on the Preferences tab of the Station Options dialog box.
Configuration Files and Type Palettes
In TestStand versions 2.0 through 3.0, TestStand installed type palettes in the Cfg directory. Also, in TestStand 3.0, the TestStand 2.0 and 2.0.1 type palette files were installed in the Cfg\Compatibility directory, which is used for the Save As feature. In TestStand 3.1, both directories are now located in the Components directory.
Note You should not use the Cfg or Cfg\Compatibility directories for saving your type palette files.
If you create a new type palette, the type palette location defaults to the User\TypePalette directory. If you are using the Save As feature in TestStand, save your type palette files in the following directory: Components\User\Compatibility\<Version>.
Configuration Files and the TestStand Deployment Utility
The TestStand Deployment Utility also allows users to create an installer that sets a non-default location from the configuration file directory.
To specify the configuration files directory, click the Advanced Options button on the Installer Options tab of the Deploy TestStand System dialog box to launch the Advanced Installer Options dialog box.
Running Executables from Deployment Installers
The TestStand Deployment Utility allows you to create an installer in which you can run a sequence of user-specified commands. For example, you can specify an executable and its command-line arguments.
To specify the commands, click the Custom Commands button on the Installer Options tab of the Deploy TestStand System dialog box to launch the Custom Commands dialog box. You can specify the executable, the command-line arguments, and the order of execution in this dialog box. The dialog box also includes a set of macros for entering special directories into the command-line arguments.
You can also display a dialog box which shows what command is currently executing and request a reboot after all commands are finished.
Database Logging Enhancements
TestStand 3.1 includes the following improvements to the process model database logging functionality:
