• NI-CAN Overview CAN interfaces meet the physical and electrical requirements for in- vehicle automotive networks based on CAN. All CAN interfaces include NI-CAN device driver software, with which you can import CAN channels from V ector database files or create them in an easy-to-use u tility and p rogram using a hig h-level API. With a National Instruments CAN interface and NI-CAN software, you can use a desktop, industrial, or notebook PC running Windows for a variety of CAN applications, including automotive testing and diagnostics, prototype design, factory automation, and machine control. CAN Bus and Analog Data Synchronization Recent advances in automotive test applications demand tighter integration of CAN and other measurement devices. In many applications, you need to synchronize the physical parameters measured in time to correlate the data. Y ou can program this synchronization in software, but OS latency sometimes introduces unacceptable delays for certain automotive test applications. National Instruments CAN, data acquisition, vision, and motion boards for PCI are equipped to share timing and triggering signals. In a system, a CAN board can share timing and triggering signals with data acquisition, image acquisition, or motion control boards, basing their actions on these signals. Determinism is maintained between the trigger signal and the desired response because timing and triggering signals are handled in hardware. The host PC software interacts only to retrieve the data once it is acquired or to write new data. Synchronization is available for PXI, PCI, and PCMCIA-CAN devices. For PXI modules, the timing signals are shared in the PXI trigger bus on the backplane; therefore, you do not need additional cables to take advantage of synchronization. For PCI boards, you can use a RTSI bus cable to share the signals. For PCMCIA-CAN, a synchronization cable connects external timing and triggering signals to the card to achieve synchronization between PCMCIA-CAN and PCMCIA, USB, or PCI data acquisition hardware. LabVIEW Real-Time Compatibility PCI and PXI CAN hardware works with LabVIEW Real-Time running on a PC or a PXI controller for deterministic control. Y ou can download your existing NI LabVIEW application to the target without specialized real-time OS programming knowledge. The real-time performance and synchronization mean y ou can use a standar d PC o r PXI chassis for applications such as rapid control prototyping, hardware-in-the-loop testing, and data logging. Common Hardware All National Instruments Series 2 CAN devices use the Intel 80386EX microprocessor to handle communications directly on the interface device. The 80386EX provides a dedicated environment for reliable, high-performance CAN communications protocol stack execution. Because acquisition and transmission timing occur on the board, CAN frames are not lost due to OS activity such as hard drive access, mouse movements, or virus scans. The physical layer of all National Instruments CAN devices fully conforms to the ISO 11898 physical layer specification for CAN and is optically isolated to 500 V . Y ou can interface to the CAN bus using a 9-pin male D-Sub (DB9) connector. The Philips SJA1000 CAN controller implements typical ISO 11898 CAN functionality and offers additional functionality to aid in system development, such as listen-only mode, sleep/wakeup mode, error counter access, and self-reception (echo) mode.

High-speed CAN interfaces can communicate with devices using transfer rates up to 1 Mb/s. Typical high-speed devices include antilock brake systems, engine control modules, and emissions systems. Low-Speed/Fault-Tolerant CAN Hardware Low-speed/fault-tolerant CAN interfaces can communicate with devices up to 125 kb/s and offer transceivers with fault-tolerant capabilities. Typical low-speed/fault-tolerant devices in an automobile include comfort devices such as seat and mirror adjusters. Single-Wire CAN Hardware Single-wire CAN interfaces can communicate with devices at rates up to 33.3 kb/s (88.3 kb/s in high-speed mode). Typical single-wire devices within an automobile include comfort devices such as seat and mirror adjusters. Software-Selectable CAN Hardware You can configure the software-selectable CAN interface for high-speed, low-speed/fault-tolerant, or single-wire CAN. Multiple-transceiver hardware offers the perfect solution for applications that require a combination of communications standards. NI-CAN Communications Software National Instruments ships CAN d evices with NI-CAN software for Windows 2000/NT/XP/M e/98. NI-CAN software includes device drivers that you can use for application development and firmware that runs o n the e mbedded I ntel 80386EX microprocessor. The NI-CAN d evice dr ivers are full 32-bit drivers designed for Windows 2000/NT/XP/Me/98. These device drivers are compatible with NI LabVIE W and LabW indows/CVI as w ell as standard programming environments such as Microsoft Visual C/C++, Borland C/C++, and Visual Basic 6. The firmware implements time-critical features provided by the NI-CAN software. NI-CAN software provides flexible yet easy-to-use functions for configuration and I/O on CAN. The Intel 80386EX microprocessor on an NI-CAN interface provides the operating environment for the CAN protocol communications stack. CAN specifies timing requirements to ensure reliable, deterministic bus operation. In a typical system, a National Instruments CAN interface must provide the necessary system responsiveness. Because the majority of the CAN protocol executes on the embedded Intel 80386EX microprocessor on NI CAN interfaces, you can achieve improved response to incoming messages. Embedded CAN protocol stack execution also results in more deterministic network performance because the onboard microprocessor is dedicated to CAN communication activities. CAN Programming With NI-CAN software, you can import CAN channel database files that use the V ector format (.dbc). A CAN frame can contain multiple values. By importing scaling information from the database files, you can easily convert these values into channels with engineering units (such as °C or kPa). Y ou can either import the scaling information directly into an application or into Measurement & Automation Explorer (MAX), where you can edit channels. Alternatively, you can configure channels directly in MAX. NI-CAN software provides two different application programming interfaces (APIs) – channel and frame, with which you can develop applications customized to your test and simulation requirements. The channel API provides access to the CAN bus in easy-to-use engineering units, using channels. Therefore, it is recommended for customers w ho ar e new to NI-CAN. The channel API simplifies multiple device integration and synchronization. With the frame API, which provides lower-level access to the CAN bus, you can read and write raw frames on the network. The frame API is recommended for users that require low-level access to the CAN bus. Controller Area Network (CAN) Interfaces 2 National Instruments • Tel: (800) 813 3693 • info@ni.com • ni.com
