An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control.Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field connections.
RAPIEnet – Real-time Automation Protocols for Industrial Ethernet; Honeywell SDS – Smart Distributed System – Originally developed by Honeywell. Currently supported by Holjeron. SERCOS III, Ethernet-based version of SERCOS real-time interface standard; SERCOS interface, Open Protocol for hard real-time control of motion and I/O
In smaller SCADA systems, the supervisory computer may be composed of a single PC, in which case the HMI is a part of this computer. In larger SCADA systems, the master station may include several HMIs hosted on client computers, multiple servers for data acquisition, distributed software applications, and disaster recovery sites.
A programmable logic controller (PLC) or programmable controller is an industrial computer that has been ruggedized and adapted for the control of manufacturing processes, such as assembly lines, machines, robotic devices, or any activity that requires high reliability, ease of programming, and process fault diagnosis.
Historical milestones in the development of industrial process control began in ancient civilizations, where water level control devices were used to regulate water flow for irrigation and water clocks. During the Industrial Revolution in the 18th century, there was a growing need for precise control over boiler pressure in steam engines.
The first industrial control computer system was built 1959 at the Texaco Port Arthur, Texas, refinery with an RW-300 of the Ramo-Wooldridge Company. [4] In 1975, both Yamatake-Honeywell [5] and Japanese electrical engineering firm Yokogawa introduced their own independently produced DCS's - TDC 2000 and CENTUM systems, respectively. US-based ...
