From Trinamic: Field Bus Systems in Motion Control - Trinamic's View

Embedded systems are used in various industries and applications for years now, making work – and increasingly everyday life – easier by transforming digital information to physical motion. Lately, companies are focusing their efforts toward further integration of these systems with sensors and copious amounts of data. By doing so, they create cyber-physical systems by merging pervasive computing and information with hardware and software, which in turn enables predictive maintenance, increases speed and intelligence, and improves the user experience.
This trend towards further integration that’s taking place in the 4th Industrial Revolution calls for a fast, secure, and reliable link between master and slaves, creating a robust bridge between the cloud and the physical edge. And while this takes place both within one single device and between different devices or machines, the paradigm is shifting towards the communication between devices, or machine-to-machine communication (M2M). Not only between devices used on the factory floor, also lab automation, office automation, and even homes see an increase in M2M communication. While M2M communication at home mostly takes place via a wireless network, professional environments will always rely on bus systems for secure, real-time communication.
However, different real-time requirements demand different approaches. Read more about these requirements and what different bus systems have to offer in our white paper on field bus systems here.
