LabVIEW RT
This section explains software installation and switch configuration for LabVIEW RT on your
PXI Express controller.
LabVIEW RT Software Installation
The following section describes the necessary steps to get your PXI Express embedded
controller set up to run LabVIEW Real-Time. In this section you will configure the controller
boot mode, verify or change IP settings, and install LabVIEW Real-Time software.
PXIe-8821 Getting Started Guide | © National Instruments | 5
Complete the following steps to install the LabVIEW RT software.
1. Boot the NI PXI Express embedded controller into the real-time operating system. Refer
to the LabVIEW RT Configuration Switches section or the LabVIEW RT Setup Menu
section in this document to configure the controller for booting into LabVIEW RT. The
PXI Express controller automatically boots into LabVIEW RT Safe Mode when no
software is installed. LabVIEW RT Safe Mode loads with the basic real-time operating
system and automatically attempts to connect to the network using DHCP. If DHCP is not
available, it then connects to the network with a link-local IP address.
Tip You can connect a monitor to the desktop PC to display startup messages
such as the IP address.
2. Open Measurement & Automation Explorer (MAX) on another computer in the same
subnet and expand the Remote Systems branch. MAX lists the PXI Express controller as
the controller model name followed by the MAC address (for example, NI-PXIe-8821).
Note The other computer must have LabVIEW, LabVIEW RT, and any
desired drivers installed.
Tip Record the PXI Express controller MAC address, located on the side of
the controller, for use in identifying the controller. You also can remove the
label and place it on the front of the controller for easier access.
3. Click the appropriate PXI Express controller entry to access the Network Settings tab in
the right pane view.
4. (Optional) Enter a name for the RT target in the Name text box.
5. (Optional) Set the network configuration options of the RT target in the IP Settings
section and click the Apply button. For information about configuring network settings,
refer to the Configuring Network Settings book, accessible by browsing to MAX Remote
Systems Help»LabVIEW Real-Time Target Configuration»Configuring Network
Settings from the Contents tab of MAX Help.
Note When any IP or identification settings are changed, you are prompted to
reboot the controller for the changes to take effect. Click Yes to reboot the RT
target automatically. You may also reboot the controller by right-clicking the
target name under Remote Systems and selecting Reboot.
After rebooting the PXI Express controller, it appears in the Remote Systems category
with the assigned name.
6. Expand the PXI Express controller view in the Remote Systems branch and select
Software.
7. Click the Add/Remove Software button in the toolbar to launch the LabVIEW Real-
Time Software Wizard.
8. Install the LabVIEW Real-Time software and device drivers that you require on the RT
target. Refer to the NI Web site at ni.com/info and enter the Info Code etspc for the
latest information about supported software.

After software installation, the controller automatically reboots, and you now can program it
using LabVIEW Real-Time.
Note Refer to the RT Getting Started Guide on your host computer for more
information about setting up your RT target.
LabVIEW RT Configuration Switches
Use the LabVIEW RT configuration switches to configure LabVIEW RT if it is installed on
the controller. If you are not using LabVIEW RT, these switches should remain in the OFF
position. The controller reads these switches only after a system reset.
The PXIe-8821 controller includes the following LabVIEW RT configuration switches:
• Switch 1—Boot LabVIEW RT: Set this switch to ON to boot LabVIEW RT.
• Switch 2—Boot Safe Mode: Set this switch to ON to boot LabVIEW RT into safe mode
to reconfigure TCP/IP settings and to download or update software from a host computer.
This switch overrides the behavior of Switch 1. Booting the controller into safe mode
does not start the embedded LabVIEW RT engine. After changing the settings or
software, reboot the controller with this switch OFF to resume normal operation.
• Switch 3—Disable Startup VI: Set this switch to ON to prevent VIs from automatically
running at startup if the controller becomes inaccessible because of a startup VI.
• Switch 4—Reset IP Address: Set this switch to ON to reset the IP address and other
TCP/IP settings to their factory defaults. Use this switch if moving the controller to a
different subnet or if the current TCP/IP settings are invalid.
Note By default, the target automatically attempts to connect to the network using
DHCP. If the target cannot initiate a DHCP connection, the target connects to the
network with a link-local IP address or 169.254.x.x.
The following figure shows the location of the LabVIEW RT configuration switches. The
switches are shown in the OFF position.
