Error -17306 When Starting Sequence File With Simple User Interface in TestStand™

Issue Details

I created a sequence file in TestStand in which I use a step to write a value in a Station Global variable. When I execute the sequence in TestStand Development System, the sequence runs correctly. However, if I start the sequence with the Simple User Interface I see the following error:

The post-expression for the step 'Statement' could not be evaluated.

Unknown variable or property name 'StationGlobals.Test'. 

Error Code:

-17306; unknown variable or property name. 

When I use a File Global or a Local variable instead of the Station Global, it works; I do not see an error. What can I do to execute my sequence with Simple User Interface? 

Solution

To resolve this issue, please review the following steps:

1. Ensure you are using the 32-bit version of TestStand, as the Simple User Interface was programmed with the 32-bit version of LabVIEW and the bitness must match between applications. 
2. Create your sequence file using the 32-bit version of TestStand.
3. In the TestStand Sequence Editor menu bar, select View>>Station Globals to open the Station Globals pane.

4. Ensure the Station Global variable you are writing to in your sequence appears in this list and its name matches the one that appears in your sequence. If it does not appear, create the Station Global variable.
   1. In the Station Globals pane, right-click within the list and select Insert Station Global.
   2. Choose the right datatype for your variable.
   3. Rename this variable to match the one you are defining in the step in your sequence.

5. Save the created Station Global by clicking the icon on the top of the screen or by pressing <Ctrl-S>. The * on the Station Globals tab will vanish, which indicates that all changes have been saved.
6. Save and close your sequence in the Sequence Editor.
7. Open and start your sequence in the Simple User Interface.

Additional Information

There are two different StationGlobals.ini files for each TestStand bitness:

• The 32-bit file is located in C:\ProgramData\National Instruments\TestStand "Version" (32-bit)\Cfg
• The 64-bit file can be found in C:\ProgramData\National Instruments\TestStand "Version" (64-bit)\Cfg 

A user interface programmed with the 32-bit version of LabVIEW takes the information about Station Globals out of the StationGlobals.ini file from the 32-bit version of TestStand. Therefore, the sequence has to be saved with the correct TestStand version to write the Station Globals into the right StationGlobals.ini file.
