LabVIEW 8.2.1 Simulation Module Readme

January 2007

The LabVIEW 8.2.1 Simulation Module (Sim) updates Sim 8.2 to address installation issues with Microsoft Windows Vista 64-bit. This release also addresses several issues with Sim 8.2. If you have Sim 8.2 installed and plan to upgrade that computer to Windows Vista 64-bit, National Instruments recommends that you install Sim 8.2.1 on that computer.

If you have already installed Sim 8.2, you must first uninstall this version before installing Sim 8.2.1.

If you install Sim 8.2.1 for LabVIEW 8.2.1, National Instruments recommends that you mass compile the Simulation VIs and Functions. Complete the following steps to mass compile these VIs and functions.

  1. Launch LabVIEW.
  2. Select Tools»Advanced»Mass Compile.
  3. Browse to the labview\vi.lib\Simulation\ folder.
  4. Click Current Folder. LabVIEW displays the Mass Compile dialog box.
  5. Click Mass Compile to start mass compiling this folder.

After LabVIEW finishes mass compiling this folder, mass compile the following folders:

National Instruments recommends that you also mass compile any VIs you created with earlier versions of the LabVIEW Simulation Module.

What's New in 8.2

The LabVIEW 8.2 Simulation Module incorporates the following new features:

Running Simulations on Embedded Devices

You can develop and execute simulations on an embedded device. To use this feature, you must install LabVIEW for the embedded device on which you want to run the simulation.

External Model Interface

You can define a dynamic system model in C++, compile this model to a dynamic linked library (DLL), and call this DLL from the LabVIEW simulation module. For examples that use this feature, refer to the labview\examples\simulation\External Model Interface\ directory.

Miscellaneous Changes and Updates

Documentation Changes and Updates

Installation/Upgrading Instructions

Complete the following steps to install the LabVIEW 8.2 Simulation Module.

  1. Install LabVIEW 8.2 Full or Professional Development System.
  2. Activate your copy of LabVIEW.
  3. Launch LabVIEW at least once, then close the application.
  4. Insert the LabVIEW 8.2 Simulation Module installation CD.
  5. Run the setup.exe program.
  6. Follow the instructions that appear on the screen.

Note: When loading simulation VIs saved in previous versions of LabVIEW, LabVIEW might search for .xnode files. Let the search run, and LabVIEW will find the files. After you save the VI in LabVIEW 8.2, this issue no longer occurs. You also can select Tools»Advanced»Mass Compile to update an entire directory of VIs to LabVIEW 8.2.

Accessing the Help and Examples

The LabVIEW Simulation Module Help contains conceptual, how-to, and reference information about the Simulation Module. Complete the following steps to access this help file.

  1. Launch LabVIEW.
  2. Select Help»Search the LabVIEW Help to launch the LabVIEW Help.
  3. Click the Contents tab.
  4. Navigate to the Simulation Module top-level topic.

The LabVIEW Simulation Module examples are located in the labview\examples\Simulation\ directory. You also can access these examples by launching LabVIEW and selecting Help»Find Examples.
