Low-Speed CAN And LIN Interfaces Fit NI CompactDAQ Apps

Newbury, England: The National Instruments C Series NI 9861 CAN interface and NI 9866 LIN interface are the first low-speed control-area network (CAN) and local interconnect network (LIN) modules that integrate with the entire NI CompactDAQ platform (see the figure).

As part of the company’s NI-XNET family, the modules provide engineers with 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. The module also can manage 100% bus load communication up to 125 kbits/s without dropping any frames.

The NI 9866 LIN module is also a single-port interface with integrated support for importing and using signals from local distribution frame (LDF) databases along with master/slave support and hardware-timed scheduling for master tasks. It can manage 100% bus load communication up to 20 kbits/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 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 suit real-time automotive testing applications, including hardware-in-the-loop simulation and test cell applications. Both modules support synchronisation 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 more easily in LabVIEW and LabVIEW Real-Time software as well as ANSI C/C++.
