This article explains how to restore missing Shared Variable Property categories in NI LabVIEW™ 2023 Q3.
 
You may notice that categories such as RT FIFO, Alarming, Data Binding, Scaling, and Security are not displayed in the Shared Variable Properties dialog.
 
 
This procedure applies to users of NI LabVIEW™ 2023 Q3 who require advanced shared variable configuration features and have access to the NI LabVIEW Real-Time Module and NI LabVIEW Datalogging and Supervisory Control (DSC) Module.
 
Prerequisites:
  • NI LabVIEW™ 2023 Q3 installed
  • NI Package Manager installed
  • Access to the required LabVIEW add-on modules

To resolve this issue and restore all missing shared variable property categories, follow these steps:

  1. Open NI Package Manager.
  2. Search for LabVIEW 2023 Q3.
  3. Install LabVIEW 2023 Q3 Patch 2, or the latest available patch version, to address Bug 2543964(a known issue of missing RT FIFO property in LabVIEW 2023 Q3).
  4. Install the required add-on modules:
    1. Install the NI LabVIEW Datalogging and Supervisory Control (DSC) Module (32-bit) that matches your LabVIEW version to enable Alarming, Data Binding, Scaling, and Security configuration options.
    2. Install the NI LabVIEW Real-Time Module (32-bit) that matches your LabVIEW version to enable RT FIFO functionality.
  1. Restart LabVIEW 2023 Q3.
  2. Open the LabVIEW project that contains the shared variable.
  3. Right-click the shared variable and select Properties.
  4. Verify that the following categories are visible in the Shared Variable Properties dialog:
    1. RT FIFO
    2. Alarming
    3. Data Binding
    4. Scaling
    5. Security

After completing these steps, you should be able to view and configure the Shared Variable Property categories that were previously missing from the Shared Variable Properties dialog as shown below:
 

Next Steps

  • Confirm that the shared variable is located within an appropriate project context.
  • For RT FIFO functionality, verify that the shared variable is deployed under a Real-Time target or the required library structure.
  • Review installed software in NI Package Manager to ensure all required modules match the LabVIEW version being used.
