NI-XNET Modules Maximize Project Reuse with Added Platform Support

November 10, 2011. National Instruments had introduced its C Series NI 9861 CAN interface and NI 9866 LIN interface, the newest modules in the NI-XNET family of products and the first low-speed CAN and LIN modules that integrate with the entire NI CompactDAQ platform. As part of the NI-XNET family, the new modules provide engineers with productivity advantages such as hardware-accelerated messaging and onboard processing. The single-port, low-speed C Series NI 9861 CAN interface module features integrated CAN database support for importing, editing, and using signals from FIBEX, .DBC, and .NCD files. It is capable of 100% bus load communication up to 125 kbps without dropping any frames. The NI 9866 LIN module is also a single-port interface with integrated support for importing and using signals from LDF databases along with master/slave support and hardware-timed scheduling for master tasks. It is capable of 100 percent bus load communication up to 20 kbit/s without dropping any frames.

Engineers can use the new CAN and LIN modules with the same NI LabVIEW or ANSI C/C++ software code on a variety of platforms including NI CompactDAQ, CompactRIO, PXI, and PCI. Project reuse saves time as the same applications can be used, for example, in labs with PCI; in manufacturing end-of-line tests with PXI; in portable in-vehicle communication settings with NI CompactDAQ; and in headless in-vehicle logging with CompactRIO.

With native support in NI VeriStand real-time test development software, the new modules are suitable for real-time automotive testing applications, including hardware-in-the-loop simulation and test cell applications. Both modules support synchronization and triggering with other CompactRIO and NI CompactDAQ modules. NI CompactDAQ offers a platform for portable in-vehicle network communication, in-vehicle logging and basic automotive electronics communication in a USB, Wi-Fi or Ethernet form factor.

The NI-XNET family provides a common programming interface for multiple automotive networks such as CAN, LIN, and FlexRay. With NI-XNET interfaces, engineers can develop applications for prototyping, simulating and testing these networks faster and more easily in LabVIEW and LabVIEW Real-Time software as well as ANSI C/C++. The interfaces combine the performance and flexibility of low-level microcontroller interfaces with the speed and power of Windows and LabVIEW Real-Time OS development. Engineers can easily integrate them with desktop real-time PCs and real-time PXI systems.
