You develop your applications with NI LabVIEW and the LabVIEW Real-Time Module under Windows or Mac OS X, then download and embed the program to run on your RT Series PXI embedded controller under a real-time operating system. Thus, you can use all the powerful development tools of LabVIEW to develop real-time, reliable solutions. With RT Series PXI embedded controllers, your real-time measurement and control systems capitalize on all the benefits of PXI systems, including rugged industrial construction and modularity. Build real-time PXI systems with any number and combination of PXI and Compact PCI measurement hardware modules. All RT Series embedded controllers deliver real-time deterministic performance and headless, reliable operation. NI offers embedded controllers ideal for high-performance control applications with PID control loop rates up to 40 kHz and embedded controllers ideal for lower-cost real-time applications (see Table 1). Each controller communicates with a Windows or Mac OS X computer running the LabVIEW Real-Time Module over standard Ethernet, and includes a Watchdog timer for monitoring the status of a system. performs a soft reboot of the host computer. Because the RT Series PXI embedded controllers run in a separate chassis with a dedicated power supply, the operator can shut down the host computer entirely without disrupting the embedded program. Dual-Boot Option You can use Measurement & Automation Explorer (MAX) to configure some models of the Windows-based PXI embedded controllers to dual-boot as real-time embedded controllers. With MAX on a Windows host machine, you can create floppy disks that you can use to install or remove the real-time operating system from your PXI controller without affecting the native Windows operating system. (The Mac OS X hosts will have these utilities shipped with the LabVIEW Real-Time Module.) The result is an RT Series controller that boots off a floppy disk into a real-time operating system or off the hard drive into a Windows operating system.

PXI Hardware for Real-Time Applications The modularity of PXI and open connectivity of LabVIEW make it easy to integrate a variety of I/O within your application. You can take advantage of the timing and triggering functionality of PXI to synchronize measurements across several I/O devices, increasing the performance of your real-time system. Create a custom real-time embedded solution using an RT Series PXI Embedded Controller with any number and combination of PXI plug-in modules. Built-in LabVIEW libraries help you create powerful applications with data acquisition, dynamic signal acquisition, motion control, image acquisition, and CAN communication. Use NI-VISA to integrate third-party PXI/CompactPCI modules in your application. In addition, the RT Series PXI controllers include built-in Ethernet and serial ports. You can use these built-in ports to communicate with peripheral devices while reserving slots in the PXI chassis for other measurement I/O devices. Table 2 lists all of the PXI hardware you can use with LabVIEW Real-Time, with page references for additional information.

Build your application on a host Mac OS X computer and download it directly to an RT Series embedded PXI controller. PXI-8176 RT The PXI-8176 RT is a high-performance PXI embedded controller capable of running a single PID loop at 39 kHz. With the 1.26 GHz Pentium III processor, the PXI-8176 RT is a high-end, real-time controller. PXI-8175 RT The PXI-8175 RT contains an 866 MHz Intel Pentium III processor capable of running a single PID loop at 30 kHz. PXI-8145 RT The PXI-8145 RT controller is ideal for low-cost, real-time applications. This series of PXI controllers includes a low-power Pentium 266 MHz processor capable of running a single PID loop at up to 6 kHz. The controllers module can withstand higher vibration and shock because it uses nonvolatile CompactFlash memory. With the single-board architecture and low-power processor, NI built this controller for embedded applications where space is limited.
