Controller Area Network (CAN) Modules for NI CompactRIO

Configure Page for: Print PDF Rich Text
  • 2-port, high-speed and low-speed CAN modules for low-level FPGA programming
  • 1-port high-speed and low-speed NI-XNET CAN modules for higher-level programming
  • Hardware synchronization with any CompactRIO I/O module
  • Ability to transmit/receive 100 percent bus loads for high-speed and low-speed CAN buses
  • Support for CAN databases for importing signals from FIBEX, .DBC, and .NCD files
  • Standard DB-9 male connector for each port

The NI CompactRIO programmable automation controller (PAC) is a low-cost, reconfigurable control and acquisition system designed for applications that require high performance and reliability. The system combines an open embedded architecture with small size, extreme ruggedness, and hot-swappable industrial I/O and communication modules. CompactRIO is powered by reconfigurable I/O (RIO) field-programmable gate array (FPGA) technology.

Controller area network (CAN) communication is supported on the CompactRIO platform with multiple CAN modules.

The NI 9853 and NI 9852 CAN interfaces are 2-port high-speed or low-speed CAN modules, respectively. These modules are ideal for low-level FPGA-based control and triggering applications that are programmed using the NI LabVIEW FPGA Module.

The NI 986x CAN modules are 1-port high-speed and low-speed NI-XNET CAN interfaces that are programmed with a higher-level NI-XNET API. The NI-XNET API does not have a LabVIEW FPGA interface. Instead, it features a common API that is used for other form factors that work with NI-XNET hardware, including PCI, PXI, NI CompactDAQ, and CompactRIO. As part of the NI-XNET platform, the NI 986x interfaces work well for applications requiring high-speed manipulation of hundreds of CAN frames and signals.
