Industrial Bus and Network Standards
Over the past 50 years, improved external communication links from PC-based applications like HMI software to controllers and from controllers to I/O have greatly increased productivity in manufacturing and other industrial applications. More recently, internal hardware buses at the PC and the controller level have also improved, boosting performance and cutting costs. This white paper discusses the history of the industrial bus and all the network standards. Where did it start? Where is it going? Where do USB and Ethernet fit into the equation?
