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.
Features include precise synchronised timing over the network, which eliminates the need for lengthy, physical timing cables and ensures tightly synchronised measurements for accurate analysis.
The chassis offer simple daisy chaining through an integrated network switch for quick setup and expansion in distributed applications and they are a reliable operation in harsh environments with a – 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 automatically synchronizes multiple chassis for simple programming.
