Legal Information
DIAdem is the NI software for analyzing and documenting data from various sources.
For correct DIAdem performance, the following minimum requirements must be met:
Hardware
CPU | x64 compatible processor, 1.6 GHz or more |
Amount of memory | 2 GB or more |
Hard disk memory | Depending on the operating system, up to 6 GB free storage space on the system partition |
Graphic card | Color depth at least 16-bit (High Color), 24-bit, or 32-bit (True Color) recommended |
Screen resolution | From 1280x800 with a scaling step of 100% |
- Windows 10 64-bit
- Windows Server 2019
- Windows Server 2016
 | Note For automatic evaluation on server operating systems, NI recommends the use of the SystemLink module Analysis Automation instead of DIAdem. |
 | Note DIAdem runs only with restrictions on the N or KN edition of Windows because the multimedia support is missing. You can obtain this as "Media Feature Pack" from Microsoft and install it later. |
Administration
Firewall | The firewall displays warnings while DIAdem installs and while DIAdem launches, for the following reasons: The usireg component executes during the installation of DataPlugins. The DataFinder, which you use for searching and navigating in files, then starts. When DIAdem launches, a DNS query determines whether to license locally or whether to use a license server.If you want to be able to use all the DIAdem functions, NI recommends that you select "Do not block" for all programs listed. This also applies when you want to evaluate DIAdem. Refer to ni.com/info under the winxpsp2 info code for more information. |
Windows User Permissions | DIAdem and its components are basically executable under the pre-configured Microsoft Windows user accounts from User upwards. DIAdem must be installed with full administrator permissions. If you operate various DIAdem versions on one computer, you only have the entire range of functions in each version if you have administrator rights. |
Miscellaneous
- Internet Explorer: For the map display in DIAdem VIEW and DIAdem DAC, you need Internet Explorer version 11 or later.
- Recommended:
- Adobe Reader to display manual files - DIAdem installs the base package of Python 3.8 (64-bit) DIAdem also supports Python versions 3.6, 3.7, and 3.9 (64-bit).
Download the DIAdem installer from ni.com/downloads. NI software includes NI Package Manager to handle the installation. Refer to the NI Package Manager Help for more information about installing, removing, and upgrading NI software using NI Package Manager.
Notes
- DIAdem 2019 and later versions no longer support the projection of data with color shading or with deformation onto a 3D model of the test object.
- As of the DIAdem 2019 installation, the 64-bit version of My DataFinder replaces earlier 32-bit installations. The configuration of My DataFinder takes place in DIAdem versions 2019 or later in DIAdem. In DIAdem versions later than 2019, you configure My DataFinder using the tray icon in the Windows taskbar. C ++ DataPlugins, which are only available in a 32-bit version, need to upgrade to a 64-bit version.
- As of DIAdem 2018, you can no longer connect to My DataFinder from a remote computer.
- For the MyDataFinder in DIAdem 2021, any index files from earlier DIAdem versions must be regenerated. This occurs automatically when you launch DIAdem. Depending on how many files are to be indexed, this may take quite some time.
- Scripts written for the use on SystemLink analysis automation are subject to certain restrictions. Refer to Analysis Automation, General in the Help, for further information.
- When you activate DIAdem, you must create a NI user profile at ni.com. The evaluation period is now 7 days without a user profile. If you create a user profile, this period is extended to 45 days.
- When using the OPC UA server, a missing Windows update can lead to error messages because functions or DLLs are missing. If this error occurs, check the logfile as to whether a message describes an error in the search path extension. To eliminate this error, install the Windows Update KB2533623 at https://www.microsoft.com/download/details.aspx?id=26767.
- When loading a DAC block diagram, DIAdem now checks whether the block diagram contains outdated blocks. The block diagram can still run with these blocks, however the outdated blocks are identified with a label. Please replace these by up-to-date blocks because in future versions the earlier blocks will no longer be supported.
- In order to use the following DIAdem drivers the following NI software components must be installed:
Driver | Components | Version |
ADCS | Automotive Diagnostic Command Set | >= 18.0 |
DAQmx driver | NI-DAQmx | >= 9.4 |
ECU MC | ECU Measurement and Calibration Toolkit | >= 18.0 |
XNET | NI-XNET | >= 15.0 |
- Very old commands and variables, which have been replaced by new technologies, are marked as obsolete in DIAdem. This means that these commands and variables are no longer supported in one of the upcoming DIAdem versions. On the DIAdem help page DIAdem»Searching for Obsolete Commands and Variables you can find a script which checks your scripts for obsolete identifiers.
- The previously obsolete commands DataCheckChnls and DataSelChn have been permanently removed from DIAdem. Use the Selection collection instead.
- If you install an earlier DIAdem version after you have installed the current DIAdem version, the PDF export of the earlier version might not function correctly. You can solve the issue by copying the files acfpdf*.* and cdintf*.dll from the current DIAdem program folder into the program folder of the earlier DIAdem version.
- From version 2018 onwards, DIAdem imports VBS DataPlugins in encrypted form by default. You can only import and then process a DataPlugin unencrypted if you select Import DataPlugin in the DataPlugin Settings dialog box.
- The images you use in the Picture for Tree SUD property must have a minimum size of 16*16 pixels.
- You cannot use VIs that require .NET assemblies from DIAdem through the LVRuntime object.
- SUD files from DIAdem 2021 cannot be loaded in an earlier DIAdem version.

General
- The DIAdem icon in the Windows Start menu shows the major version number.
- Right-click the buttons to scroll through the tabs in VIEW, REPORT, and SCRIPT to quickly select the tab you want.
DIAdem NAVIGATOR, DataFinder, Data Portal
- In the Data Portal, you can pin new channels automatically.
- In the Data Portal, you can create video channels by specifying the path to the video file.
- DIAdem installs a new DataPlugin that allows you to search for video files in NAVIGATOR and drag and drop them into the Data Portal to create video channels.
DIAdem VIEW
- With the new "Bird's Eye View" display type in DIAdem VIEW, you can display radar data, including road course, lane, object list, and sensor fields of view, from a bird's eye perspective. You can synchronize this data with GPS data and the detected objects in the video. Use the playback functions of VIEW to start the bird's eye view display and play back the detected objects, the associated measurement data, and the videos concurrently, or move the cursor to a specific point in time.
- As in DIAdem REPORT, you do not need to specify the x-channel in the VIEW display types if the y-channel is an xy-channel.
- The coordinates dialog box has been extended with functions for positioning the cursor.
- You can now edit all settings of a video in the redesigned video settings dialog box.
- In the video display mode, you can also use the new video channels.
- You can move or copy VIEW areas using drag and drop. Moving or copying across different worksheets is also possible. When you move or copy an area and position it behind the last worksheet, you can create a new worksheet at the same time.
- You can create a video area by dragging and dropping a video channel onto an empty area, or replace an existing video in a video area by dragging a video channel onto that area.
DIAdem Script
- The DIAdem Python environment also supports Python version 3.8.
- You can specify an external Python IDE and use it to edit Python scripts.
- The automatically generated header of new Python files contains commands to activate the external debugger. See the help for a detailed description of how to set up the external debugger.
- When creating new scripts, you can choose whether you prefer VBS or Python as the script language.
- The short code snippets of the help now show Python code as well as VBS code.
- There are new methods for moving or copying VIEW areas with a script.
- There are new methods for copying curves in DIAdem VIEW with a script.
- The conversion functions for converting one channel type to another have been renamed so that they all start with "ChnConvert", for example, ChnConvertNumericToTime, ChnConvertNumericToWaveform, or ChnConvertTextToAssignment.
- The dialog box for selecting files when testing analysis automation procedures for SystemLink TDM is now resizable to allow the use of long file names.
Dialog Editor
- The slider control provides you with a new input tool in your user dialogs.
Preview Features
Preview features give an outlook on features in future versions. The functions to be unlocked are still under development and the user interface, the API, or the scope of functions may change. Enable this function in the Settings»DIAdem Settings» Preview Features dialog box.
- The DIAdem Python environment also supports Python version 3.9.
- DIAdem supports complex channels. You can load and save complex channels. You can convert numeric channels to complex channels and vice versa.
- The Bus Log Converter also supports the TTTech TTL format.
For more information on DIAdem, go to the DIAdem help Help»Contents.
Use Help»Examples in DIAdem to start the DIAdem ExampleFinder. You can find DIAdem examples in the examples directory below the program directory. You can modify examples to suit your needs, or you can copy and paste parts of the examples into your own files.
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 4.6.2, 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 4.6.2 separately before you install NI software.
For more information about automating the installation of NI products, refer to Automating an Online or Offline Installer in the NI Package Manager Help.
DIAdem no longer supports Windows Vista/XP/7/8.x, Windows Server 2003/2008/2012, or other 32-bit Windows operating systems. Versions of this product that ship after May 1, 2021 may not install or execute correctly on these operating systems.
