White paper by Yokogawa: When distributed control systems (DCS) first appeared on the industrial automation scene in the mid-1970s, the focus was on control and operator interface.

Furthermore, automation suppliers have moved away from the proprietary hardware, software, and communications of the past, incorporating commercial-off-the-shelf (COTS) technologies where practical and appropriate to do so. At the same time, plant engineering and opera-tions groups have adopted many of the same standards already in place at the enterprise IT level, and today’s DCSs reflect this.
