NI CompactRIO with TSN synchronization

National Instruments integrates TSN synchronization with its CompactRIO platform

  • National Instruments (NI) launches new CompactRIO controllers with NI-DAQmx driver and Time Sensitive Networking (TSN) technology.
  • These controllers provide deterministic communication and synchronized measurement capabilities.

NI reports that it is the first company to market an embedded industrial system supporting TSN technology for the next evolution of the IEEE 802.11 Ethernet standard.

Acquiring synchronized data from multiple distributed systems is tricky. TSN technology enables synchronization of distributed systems over networks without the need for synchronization cables.
# Main features of CompactRIO controllers:

  • Less than microsecond synchronization via TSN technology instead of the standard Ethernet interface for synchronized and distributed measurements and control/command operations.
  • Intuitive NI-DAQmx driver reduces access to measurement results compared to previous versions of CompactRIO controllers.
  • Open and secure processing in the network periphery with the operating system NI Linux Real-Time.
  • Data analysis and monitoring/control via a processor and an embedded FPGA programmable with LabVIEW FPGA module.
  • Operation over an operating temperature range from -40 °C to 70 °C and shock and vibration resistance up to 50 g and 5 g respectively.

The NI-DAQmx driver of the CompactRIO controller family provides direct access to I/O via ready-to-use features. By combining this driver with the NI Linux Real-Time operating system, applications can take advantage of the entire IP ecosystem available for Linux (Security Enhanced Linux, or SE-Linux for example).
