TSN-supporting controllers offer sub-µs synchronisation

05 March, 2018

National Instruments (NI) has announced a range of industrial controllers that incorporate TSN (Time Sensitive Networking) and NI-DAQmx, and offer deterministic communication and synchronised measurements across standard Ethernet networks. The controllers, part of the CompactRio  family, will allow users to synchronise distributed systems across networks, eliminating the need for costly synchronisation cables. NI says that they will boost performance, help to improve productivity, and make installations more flexible.

NI claims it was the first to market with industrial embedded hardware that supports TSN, the next evolution of the IEEE 802.11 Ethernet standard which helps to achieve accurate, reliable and synchronised data across distributed nodes in IIoT (Industrial Internet of Things) applications.

The new controllers with TSN-enabled Ethernet ports offer:

•  sub-microsecond synchronisation using TSN over standard Ethernet for tightly synchronised, distributed measurement and control;

•  shorter time-to-measurement than previous CompactRio controllers because of the “intuitive” NI-DAQmx driver software;

NI says its new controllers with TSN Ethernet ports will boost performance, improve productivity, and make installations more flexible

•  open and secure processing at the edge of the IIoT using NI’s real-time Linux operating system;

•  high-performance data analysis and control with an onboard FPGA, that can be programmed using LabView FPGA; and

•  reliable operation in harsh environments with an operating temperature range –40 to +70°C, shock resistance up to 50g, and vibration resistance up to 5g.

The NI-DAQmx driver software allows users to access I/O directly from ready-to-use functions. Combined with the real-time OS, it allows users to take advantage of Linux IP such as Security Enhanced Linux (SE-Linux).
