RSU

Distributed control systems (DCS)

Automated industrial automation systems are becoming increasingly larger and more complex every year, occupying large areas and incorporating numerous sensors. To control these systems, modern, efficient solutions called DCSs (Distributed Control Systems) are used.

DCSs comprise multiple controllers distributed over a large area, along with input and output modules. This approach ensures maximum similarity between the structure of the distributed system, its operating algorithm, and the structure of the automation object itself. Data collection and processing functions, computation, and control are distributed among a large number of controllers.

Each controller in the system works with its own set of input/output devices and serves a given part of the controlled object.

The emergence of distributed control systems is a consequence of the decentralization of control and the movement of controllers closer to the controlled objects. These changes have become characteristic of all industrial automation systems; concentrated control systems are a rarity.

What is RSU?

A DCS is a system comprising multiple devices located in a given space. Each device is independent of the others but interacts with them to achieve a unified result. In some cases, system elements may be located at opposite poles of the globe and interact via the internet.

Areas of application of DCS

Distributed control systems are widely used, and their equipment is employed in a wide variety of industries, including the chemical and petrochemical industries, oil production and refining, gas extraction, metallurgical plants, and the food and energy industries.

Modern DCS systems are subject to a number of mandatory requirements. These include properties such as security and fault tolerance, ease of configuration and development, consistent database configuration, support for remote infrastructure objects, and a user-friendly and practical interface.

Distributed control systems are designed to connect users to resources. They must be as transparent as possible and presented as a single computer system. Standard syntax and semantics must be used to invoke service commands.
