NI-DCPower is an interchangeable virtual instrument (IVI)–compliant instrument driver, and it features a set of operations and properties that exercise the functionality of the power supply or SMU and includes an interactive soft front panel and examples.
NI-DCPower 19.5 has the following requirements:
Refer to the LabVIEW Readme for additional system requirements and supported operating systems for LabVIEW.
NI-DCPower 19.5 supports the following operating systems:
1 NI software installs VC2015 Runtime and .NET 4.6.2. Windows 8.1 and Windows Server 2012 R2 require Microsoft updates to support these items. Refer to Microsoft KB2919442 and KB2919355 for more information about how to install these updates.
2 NI software is signed with a SHA-256 certificate. Windows 7 SP1, Windows Embedded Standard 7 SP1, and Windows Server 2008 R2 SP1 require Microsoft updates to support SHA-256. Refer to Microsoft KB3033929 for more information about how to install this security update.
Note In 2016, NI-DCPower dropped support for Windows Vista, Windows XP, Windows Server 2003, and installations of Windows 7 without any service packs. NI-DCPower 19.5 will not install or run on an unsupported OS. You cannot deploy or distribute applications that use NI-DCPower 19.5 to an unsupported OS. Additionally, after installing NI-DCPower 19.5, you cannot use any installers built on this computer with any version of LabVIEW, LabWindows™/CVI™, NI TestStand™, or Measurement Studio on an unsupported OS.
For more information about the changes to our OS support for 2016, refer to KB 79UC78LS, Why Does My NI ADE Installer Fail on Windows XP/Vista and Windows Server 2003?.
Note Support for Windows 32-bit operating systems may require disabling physical address extension (PAE). To learn how this might affect your system and what actions you might need to take, refer to NI Software Fails When Physical Address Extension is Enabled.
NI-DCPower 19.5 supports the following application software versions, including service packs. If you are not using NI application software, refer to Microsoft Visual Studio Support.
|Application Software||Versions Supported by NI-DCPower|
|LabVIEW||2016, 2017, 2018, 2019|
|LabVIEW Real-Time Module3||2016, 2017, 2018, 2019|

3No support for PXIe-4162/4163 source measure units.
If you are using the NI-DCPower .NET Class Library, the .NET Framework 4.0 (minimum) is required. The NI-DCPower .NET Class Library can be used with the Visual C# or Visual Basic .NET programming languages in any Visual Studio version that can target the .NET Framework 4.0 or the .NET Framework 4.5.
To use the .NET API, you must select the .NET Framework 4.0 Languages Support or the .NET Framework 4.5 Languages Support packages in the NI-DCPower installer to install the .NET class libraries in addition to the NI device driver. For information about versions of the .NET Framework and the drivers each supports, as well as the download location of the installer files, refer to National Instruments .NET Driver Support.
NI automates LabVIEW NXG installation using NI Package Manager. Visit ni.com/info and enter the Info Code NIPMDownload to download NI Package Manager. Refer to the NI Package Manager Manual for more information about installing, removing, and upgrading NI software using NI Package Manager.
The following list details the hardware models supported in NI-DCPower 19.5:
NI 411x, 413x, 414x, and 4154 Power Supplies and SMUs

NI‑DCPower 19.0 dropped support for Express VIs in LabVIEW. Existing code created with earlier versions of NI‑DCPower and that contains Express VIs will continue to execute, but the Express VI cannot be reconfigured from a dialog box.
To reconfigure an Express VI, right-click the Express VI and select Open Front Panel»Convert. This will convert the Express VI to code that you can configure on the block diagram. NI recommends converting Express VIs to code before using the Code Conversion Utility in LabVIEW NXG to convert code for LabVIEW NXG.
