NI integrates Time Sensitive Networking into CompactDAQ platform

The nature of physical systems test is rapidly changing, NI finds, 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 synchronization and systems management, especially using today’s industrial networking technologies. NI is working to help define TSN, the next evolution of the IEEE 802.1 Ethernet standard, to deliver distributed time synchronization, low latency and convergence of time critical and general networking traffic. The cDAQ-9185 and cDAQ-9189 provide tight time synchronization with TSN to simplify and improve scalability of synchronized, distributed systems.

 

Features include:

– Precise synchronized timing over the network, which eliminates the need for lengthy, physical timing cables and ensures tightly synchronized measurements for accurate analysis.

– Simple daisy chaining through an integrated network switch for quick setup and expansion in distributed applications.

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

– Software abstraction through the NI-DAQmx driver that automatically synchronizes multiple chassis for simple programming.

 

“These new chassis automatically synchronize measurement data using network-based time. This allows accurate synchronization over long distances, which greatly simplifies customer setup and systems management of high-channel-count and distributed systems,” NI says, “This new, innovative method of synchronization combined with the signal processing libraries in LabVIEW system design software helps engineers quickly collect and analyze results, which drives faster test completion and higher efficiency.”
