Distributed Control System (DCS) Key Terms

Talk the talk using DCS key terms

Distributed control systems are prevalent in manufacturing and utility industries because they are connected to a single control panel. Knowing distributed control key terms can help you with buying or upgrading DCS systems. A distributed control system uses a number of controllers (all connected to a network) for different functions. DCS applications are more prevalent than before because they've been designed for smaller companies, not just the huge ones that need remote connections to function efficiently.

 

Microprocessor, also known as central processing unit (CPU)

Microprocessors-those tiny chips that store incredible amounts of information and perform myriad functions-are the basic components of distributed control systems.
Try: Check out How Stuff Works for insights into the microprocessor and its capabilities.

Digital technology

Digital technology is taking over from analog technology because it's faster and has more functionality. DCS uses digital technology.
Try: HelloDirect.com, an online telecom resource, describes the difference between analog and digital technology.

Remote control panels

Remote control panels, digital communication units (DCU) and remote transmission units (RTU)-these all perform the same functions and are made up of I/O modules, terminal blocks, a processor and a communications interface.
Try: Remote control panels are used in PCs  with DCS. GlobalSpec discusses DCS and the role played by remote control panels.

Dedicated system

A dedicated system is a DCS system designed to perform a number of tasks to produce something; for instance, the assembly of "widgets." A dedicated system for making widgets would use remote control panels to analyze the quality of material, take the parts of the widget and assemble them and ultimately wind up with a widget.
Try: In real life (and in real-time) the Norway Railway wanted to integrate its various communication needs into one system, including all the communication requirements of its train stations. It used a dedicated system to connect more than 500 stations and 650 tunnels.

DCS applications for small businesses

DCS was developed for huge, remote automation needs. However, new applications for small businesses are being developed because DCS provides integration and functionality, which smaller manufacturers also require.
Try: ControlGlobal.com discusses DCS applications (designed by Honeywell) for smaller manufacturers.

Distributed control system supplier

A distributed control system supplier is the term used for the original manufacturer or a provider of DCS manufacturers' products.
Try: Emerson provides information for businesses and designs the systems. GlobalSpec also provides a list of DCS suppliers, which can provide you with further information on all the DCS can do. If you're not able to see the list immediately, then you need to register online for the list. Registration is free.
