Types of distributed modular I/O slave devices that use IO-Link communications include specialty sensors for measurement, position, and color detection, valve manifold control, and industrial RFID processors and heads.
The idea of putting an Ethernet connector on a sensor (RJ-45 was used in the article) as being to large, too inconvenient. M-12 threaded connectors also provide Ethernet connectivity. They have a different keying so that they cannot be mixed with regular M-12 connectors, the most common connector for sensors today. Connector is not a reason to reject Ethernet.
IO-Link in combination with Ethernet in its various protocols sounds very promising though. I'm looking forward to seeing IO-Link/Ethernet adapters gain much higher industrial visibility.
I 'd like to hear more about how this will combine with RFID and ethernet. Once these get to be ubiquitous and connected to the internet we will have an Internet of things and Sensors. With the advent of distributed AI, we can just call it skynet.
The Smart Emergency Response System capitalizes on the latest advancements in cyber-physical systems to connect autonomous aircraft and ground vehicles, rescue dogs, robots, and a high-performance computing mission control center into a realistic vision.
