As part of the evolution of the IoT, more information is needed than simply increasing the number of sensors in a system and measuring more modalities. I’ve previously spoken about clever partitioning of systems and breaking an IoT system into what needs to happen at the edge (sensor or gateway) and what happens in the cloud. Extreme IoT requires going beyond stationary, connected and sometimes dumb sensors, irrespective of how much data they produce. What if the target is mobile? The complexities of an Internet of Moving Things goes beyond simple data collection into how to track and measure intelligently. However the information about “when” a measurement happens can be almost as important. Machine learning about what conditions signify can only be gained if you can synchronize an event to a time stamped set of data.
It’s only then that the real magic of IoT (moving data into value or wisdom) can be unlocked.
Time Sensitive Data in Industrial Ethernet
Two critical elements that come into play for industrial applications are the need for guaranteed “on-time” reliable data delivery and accurate time-stamped data for event sequencing and process analysis. When the data absolutely, positively has to be there at the right moment, deterministic networking can enable everything from motion control applications to process control and factory automation applications. Time-stamped data can be used in algorithms to reveal trends across the factory that deepen the value of the information.
At the 2017 IoT Solutions World Congress in Barcelona, several ideas were presented to show the value and readiness of Time-Sensitive Networks (TSN) and new IEEE standards to support real-time control and synchronization of machinery and processes. The vision was to enable flexible manufacturing for Industrial IoT and Industry 4.0 through deployment of open, standard deterministic networks in production facilities. Analog Devices was one of 17 partners behind an award-winning solution.
From Rant to Reality:
As the IoT evolves at such a rapid pace, solutions should be engineered with the flexibility to meet the current and future requirements. For example, ADI’s fido5000 Real-time Ethernet, Multi-protocol (REM) switch is designed for all of today's major Industrial Ethernet protocols and its configurable blocks will also make it easier to support future IEEE 802.1 TSN protocols.
