NI RT Management by NI - Toolkit for LabVIEW Download

The RT Management library provides an easy to use API for the System Configuration, FTP, and WebDAV APIs in LabVIEW. There are two main components or APIs that provides commonly used functions used in the configuration of and interaction with RT targets.

File Transfer Behavior API
This provides an abstract interface for file transfer protocols. There are two included implementations, FTP and WebDAV, but a user can add their own protocol by inheriting from the File Transfer Behavior.lvclass, overriding the required methods, and following the development examples set by the FTP and WebDAV implementations. The file transfer behaviors can be switched at run time for different targets or even the same target by simply toggling the class passed into the This allows you to use a single API for both file transfer protocols, or any further protocol implemented. The included implementations for the FTP and WebDAV protocols work around many of the quirks amongst different NI RT targets, so that the File Transfer Behavior works seemlessly across every RT target NI manufactures with no needed workarounds or changes in the use of the API.

RT Management API
This API wraps the above File Transfer Behavior API and the NI System Configuration API to provide commonly used behaviors when configuring an RT target, such as configuring VI server or installing a startup application. This API, like the File Transfer API, handles many of the differences between NI targets, so that the same API can work seemlessly across any RT target.

Release Notes (Jul 28, 2016)

-Fixed bug in Delete where not all paths to exclude would be excluded.
-Fixed bug in Delete where the VI would error if a path to exclude didn't actually exist on the target.


LabVIEW RT Support for the Pickering IVI Driver

There are 2 versions of the Pickering pi40iv driver, with different target devices.

The normal installation of pi40iv installs a driver which is capable of addressing both Pickering PXI cards and Pickering LXI products,
but NOT from LabVIEW RT. A second version of the driver is provided, pi40ivrt, which is capable of addressing Pickering PXI products
from both Windows and LabVIEW RT, but NOT LXI products.

To use the LabVIEW RT capable driver, there are a few steps required to place the appropriate software onto the RT target system.

a) The Pickering VISA driver should be copied to the RT target system, including the INF files required for the RT system to identify the Pickering cards.

b) IVI system dll's should be copied to the RT system

c) The Pickering pi40ivrt driver should be copied to the RT system

d) The Pickering pi40iv.ini file defining card topologies should be copied to the RT system

Important: first copy the files for the Pickering VISA driver as detailed here

Then copy these additional files:



(copy all dll's with Ivi prefix)


(location may vary, search the Windows folder system for a copy)


C:\Program Files\IVI Foundation\IVI\WinNT\Drivers\pi40iv\pi40iv.ini


C:\Program Files\IVI Foundation\IVI\WinNT\bin\pi40ivrt32.dll


NOTE: The LabVIEW wrapper for the pi40iv driver is provided in two versions, one linked to the 'normal' pi40iv and one to pi40ivrt for RT systems (and indeed any VISA system). Make sure the correct wrapper is selected in LabVIEW.

Pickering VISA driver (pipx40) and LabVIEW™ Real-Time

RT system with Phar Lap ETS Real-Time Operating System

The Pickering VISA driver, pipx40, is suitable for use with LabVIEW RT systems, here's how.

  • Install pipx40 normally onto the development system
  • Make sure that a copy of the pipx40 LabVIEW library is installed in the instr.lib folder of the LabVIEW installation
  • Transfer the Pickering Windows INF files to the RT system - this allows RT to recognize Pickering cards
  • Transfer a copy of the pipx40_32.dll to the RT system

Files to be copied to the remote RT system:

C:\Program Files\IVI Foundation\VISA\WinNT\pipx40\LabVIEW RT\*.infd>  /ni-rt/system
C:\Program Files\IVI Foundation\VISA\WinNT\bin\pipx40_32.dlld>   /ni-rt/system

*Note: On older installations the source files may be located in: C:\VXIPNP\WinNT folder system 

RT system with NI Linux Real-Time Operating System

Before installing the Pickering PXI VISA (pipx40) driver on a remote system running NI Linux RT, the following prerequisites must be met:

  • LabVIEW and the LabVIEW RT module are installed on your local system with the Pickering Pipx40 wrapper
  • The target system is connected to the local area network with SFTP/SSH access
  • LabVIEW RT and NI VISA area already installed on the target system

Installation step:

  1. Download the latest driver version for “pipx40 for NI Linux RT” from 
  2.  Copy the file to the target system. 
  3. Login to the target system, and navigate to the location where the driver file was copied. 
  4. Extract the tar.gz file. 
  5.  # tar zxvf  [installation package tar.gz file]

  6. Navigate to the extracted folder.
  7. Run the install script  

     # sh

This will install the Pickering Pipx40 PXI VISA driver files and .inf files for NI VISA to recognise Pickering cards.

LabVIEW Real-Time (RT) Configuration

LabVIEW Real-Time (RT) combines easy-to-use LabVIEW programming with the power of real-time systems. When you use a National Instruments PXI Controller you can install a PXI-CAN card and use the NI-CAN API to develop real-time applications. For example, you can simulate the behavior of a control algorithm within a CAN device, using data from received CAN messages to generate outgoing CAN messages with deterministic response times. This and other real-time applications can also be developed if you are using CompactRIO as your LabVIEW RT system. You can install a CompactRIO CAN module and use the NI-CAN software and the LabVIEW FPGA I/O to develop your applications.

When you install the NI-CAN software, the installer checks for the presence of the LabVIEW RT module. If LabVIEW RT exists, the NI-CAN installer copies components for LabVIEW RT to the Windows system. As with any other NI product for LabVIEW RT, you then download the NI-CAN software to the LabVIEW RT system using the Remote Systems branch in MAX. For more information, refer to the LabVIEW RT documentation.

USB-847x hardware is not supported under LabVIEW RT.

PXI System

After you have installed the PXI CAN cards and downloaded the NI-CAN software to the LabVIEW RT system, you need to verify the installation. Within the Tools menu in MAX, select NI-CAN»RT Hardware Configuration. The RT Hardware Configuration tool provides features similar to Devices & Interfaces on the local system. Use the RT Hardware Configuration tool to self-test the CAN cards and assign an interface name to each physical CAN port.

To use the Channel API on the LabVIEW RT system, you must also download channel configuration information. Right-click the CAN Channels heading, then select Send to RT System. This downloads all information under CAN Channels to the LabVIEW RT system, so you can execute the same LabVIEW VIs on the LabVIEW RT system as on the Windows system.

CompactRIO System

After you have installed the CompactRIO CAN modules and downloaded NI-RIO and NI-CAN software, you need to enable the CompactRIO Reconfigurable Embedded Chassis for use in LabVIEW. For instructions on how to enable the CompactRIO Reconfigurable Embedded Chassis for use in LabVIEW, refer to the MAX help.

To use the Channel API on the LabVIEW RT system, you must download the channel configuration information. Right-click the CAN Channels heading, then select Send to RT System. This downloads all the information under CAN Channels to the LabVIEW RT system. To utilize the CAN channels on the CompactRIO system, you need to use Frame to Channel Conversion. For more information, refer to the Frame to Channel Conversion topic.

But I didnt dare to masturbate (I already knew how to do it and, I must admit, loved to masturbate), I was very scared that they would notice me. It is only in German films that the spy quietly jerks off outside the door.
