Based on 802.15.4 point-to-point communications, Honeywell’s Limitless switches can be configured with up to 14 devices to communicate with one receiver module. The wireless signal is received by either a panel-mount receiver, or an industrial DIN-rail module, which is then converted to an output. Outputs can be LEDs, buzzers, or standard electrical signals used by traditional controllers.
I see combatting the noisy industrial environment, wirelessly, is making some strides. I think I feel confident enough in the tech these days to use wireless in the machine shop. The little risk may have a huge payoff in mobility.
Thorough and well-written article. I completely agree with the speed of installation advantages of a wireless system. Many years ago, I had to set up a wired network to our factory floor and the time required to plan and install this older technology was significant (not to mention the time needed to troubleshoot improper hardware node connections). In many instances, wireless technology will prove to be faster and much more flexible than existing wired systems.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
