Ethernet chassis deliver tight test synchronisation

14 June 2017 Test & Measurement

The nature of physical systems test is rapidly changing as measurement systems migrate from the control room to closer to the device under test. While this shortens installation time, reduces the cost of sensor wiring and improves measurement accuracy, it creates challenges with synchronisation and systems management, especially using today’s industrial networking technologies. NI is actively working to help define TSN, the next evolution of the IEEE 802.1 Ethernet standard, to deliver distributed time synchronisation, low latency and convergence of time critical and general networking traffic.

The cDAQ-9185 and cDAQ-9189 provide tight time synchronisation with TSN to simplify and improve scalability of synchronised, distributed systems. By providing precise timing over the network, they eliminate the need for lengthy, physical timing cables and ensure tightly synchronised measurements for accurate analysis. Simple daisy chaining through an integrated network switch allows for quick setup and expansion in distributed applications.

The rugged chassis guarantee reliable operation in harsh environments with -40°C to 70°C operating temperature range, shock resistance up to 50 G and vibration resistance up to 5 G. Software abstraction through the NI-DAQmx driver automatically synchronises multiple chassis for simple programming.
