NI CompactRIO Adds Controller Area Network (CAN) Communication for In-Vehicle Data Acquisition and Control

AUSTIN, Texas - July 13, 2005 - National Instruments (Nasdaq: NATI) today introduced the new Controller Area Network (CAN) interface module for its flexible, high-performance NI CompactRIO platform. The NI 9853 module for National Instruments CompactRIO is a two-port, high-speed CAN interface that combines with NI reconfigurable I/O (RIO) technology to deliver the highest-performance in-vehicle measurement and control platform on the market. The NI 9853 module plugs into any CompactRIO chassis to offer a wide variety of capabilities for automotive and industrial applications, including monitoring in-vehicle CAN buses, reading and writing values to CAN devices such as electronic control units (ECUs) and actuators, and communicating with industrial devices such as motion drives and motors.

With CompactRIO and the NI 9853 CAN module, engineers can use the National Instruments LabVIEW graphical development environment to program the field-programmable gate array (FPGA) chip within the CompactRIO platform to respond to incoming CAN data with decisions at rates up to 40 MHz. Engineers also can take advantage of the flexibility and performance of CompactRIO to synchronize the NI 9853 CAN module with any CompactRIO I/O module offering hardware CAN and data acquisition synchronization with up to 25 ns resolution. The NI 9853 CAN module also delivers 11-bit and 29-bit arbitration ID support for communication on J1939 networks, and engineers can use NI-CAN driver software to incorporate Vector database files into their applications.

"We used the new National Instruments CAN module for CompactRIO to monitor and log CAN frames in our heavy-duty truck," said Andrew Leslie, systems engineer at PACCAR. "The small size and ruggedness of the CompactRIO platform made it the ideal solution for an in-vehicle test system that could survive in the harsh environment of our test course."

CompactRIO is an advanced embedded control and acquisition system powered by NI RIO technology, which engineers can use to define their own custom measurement hardware circuitry using reconfigurable FPGA chips found on National Instruments hardware and easy-to-use LabVIEW graphical development tools. Control and acquisition system vendors widely use FPGA devices because of their performance, reconfigurability, small size and low engineering development costs. With CompactRIO, engineers can rapidly build embedded control or acquisition systems that rival the performance and optimization of custom-designed hardware circuitry.

LabVIEW programmers no longer need specialized hardware design languages such as VHDL to take advantage of user-programmable FPGAs to create highly optimized reconfigurable control and acquisition systems. Engineers can choose from a variety of CompactRIO I/O modules, including a 100 kHz simultaneous-sampling analog I/O module, a 24 V industrial digital I/O module with up to 8 A current drive and a 24-bit dynamic signal analysis (DSA) analog I/O module for noise, vibration and harshness (NVH) testing.
