NI adds time sensitive networking to CompactDAQ platform

NI’s latest CompactDAQ chassis incorporates time-based synchronisation built on the latest Ethernet standards.

cdaq_tsn_bdrThis brings together time sensitive networking (TSN) with CompactDAQ hardware for distributed measurements.

As industrial measurement systems move closer to the device under test it is creating challenges with synchronisation and systems management.

TSN as the next evolution of the IEEE 802.1 Ethernet standard is designed to address this by supporting distributed time synchronisation, low latency and convergence of time critical and general networking traffic.

The cDAQ-9185 and cDAQ-9189 units, announced at last month’s NIWeek in Austin, Texas, have been designed to provide tight time synchronisation with TSN in scaleable distributed systems.

Todd Walter, chief marketing manager for DAQ products at NI, writes:

“These new chassis automatically synchronise measurement data using network-based time. This allows accurate synchronisation over long distances, which greatly simplifies customer setup and systems management of high-channel-count and distributed systems.”

The benefits of synchronised timing over the network include reducing the need for lengthy, physical timing cables and it is possible to daisy chain through an integrated network switch when expansion is needed.
