System Requirements

In addition to the system requirements for the LabVIEW Development System, the PID and Fuzzy Logic Toolkit has the following requirements:

  • LabVIEW 2013 Full or Professional Development System (32-bit)
  • At least 75 MB of disk space

Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW 2013.

Installation Instructions

You can install all of your LabVIEW products—including the PID and Fuzzy Logic Toolkit—using the LabVIEW 2013 Platform DVDs. Refer to the LabVIEW Installation Guide on the LabVIEW Platform DVD 1 for installation instructions and system requirements.

To request additional LabVIEW Platform DVDs, refer to the National Instruments website.

Note  If you purchased this product with an NI Software Suite or NI Product Bundle, use the installation media that shipped with your purchase to install this product.

PID and Fuzzy Logic Toolkit Updates and Notifications

National Instruments posts information about critical updates and security notifications on Visit and enter Info Code updates to access this information.

Behavior Changes

In the PID and Fuzzy Logic Toolkit 2011 and earlier, the PID Structure Conversion VI converts controllers in Parallel form to Academic form using the following transformation for the integral value: Td = K * Kd. In the PID and Fuzzy Logic Toolkit 2012 and later, the PID Structure Conversion VI converts the integral value using the following transformation: Td = Kd / K.

To continue using the behavior from the previous versions, use the VI located at <labview>\examples\control\PID\subVIs\Convert PID

Refer to the Toolkits»PID and Fuzzy Logic Toolkit»PID Control»PID Algorithms»PID Topologies topic on the Contents tab of the LabVIEW Help for more information about different forms of PID controllers.

Known Issues

You can access the software and documentation known issues list online. Refer to the National Instruments website for an up-to-date list of known issues in the PID and Fuzzy Logic Toolkit.

Bug Fixes

The following items are the IDs and titles of a subset of issues fixed in the PID and Fuzzy Logic Toolkit. This is not an exhaustive list of issues fixed in the current version of the PID and Fuzzy Logic Toolkit. If you have a CAR ID, you can search this list to validate the issue has been fixed.

ID Fixed Issue
367762 The PID Advanced does not have a terminal that indicates autotuning completion
390912 The PID Advanced cannot be used in parallel
384634 The PID Structure (DBL).vi is configured incorrectly in the “Modified Ziegler-Nichols” instance

Accessing the Help

Refer to the LabVIEW Help, accessible by selecting Help»LabVIEW Help from LabVIEW, for information about the PID and Fuzzy Logic Toolkit.

Finding Examples

Select Help»Find Examples from LabVIEW to launch the NI Example Finder. LabVIEW examples for the PID and Fuzzy Logic Toolkit are located in the labview\examples\control directory. You can modify an example VI to fit an application, or you can copy and paste from one or more examples into a VI that you create.

Automating the Installation of NI Products

You can automate the installation of most NI products using command-line arguments to suppress some or all of the installer user interface and dialog boxes. However, starting with the August 2012 releases (products using NI Installers version 3.1 or later), you may need to perform additional steps before or during a silent installation of NI software.

If the NI product you are installing uses Microsoft .NET 4.0, the .NET installer may run before any NI software installs and may require a reboot before the installation of NI software begins. To avoid a .NET reboot, install .NET 4.0 separately before you install NI software.

How to Use NI Software with Microsoft Windows 8

When you install National Instruments software on Microsoft Windows 8, you will notice a few additional tiles on the Start screen, including shortcuts to NI application software products such as NI LabVIEW, Measurement & Automation Explorer (MAX), and the new NI Launcher.

Using NI Launcher

NI Launcher helps you find and launch installed NI products. It provides you with a method of finding NI products similar to the Start menu in previous versions of Microsoft Windows. To use NI Launcher, click the NI Launcher tile on the Start screen. NI Launcher launches the desktop and opens a menu containing a list of NI products. Click any NI product to launch it.

Note  MAX does not appear as a desktop shortcut when installed on Microsoft Windows 8. You can launch MAX either from the Start screen or from within NI Launcher.

Pinning Frequently Used Applications

For convenience, you can pin your most-used NI applications, such as MAX, to either the Start screen or the Taskbar on the desktop, as necessary:

Current ApplicationIcon LocationPin to Action
Windows 8 DesktopDesktop TaskbarRight-click application and select Pin to Taskbar
Windows 8 DesktopStart screenRight-click application and select Pin to Start
Windows 8 Start screenDesktop TaskbarRight-click application and select Pin to taskbar from the menu bar on the bottom of the screen

Finding All Programs

If you want to find a particular application or related files, such as documentation files, from the Start screen, you can access all installed files by right-clicking anywhere on the Start screen and selecting All apps. A list of all installed software and related files appears, in alphabetical order by creator or type.
