**Introduction to DCS System**
A Distributed Control System (DCS) is a modern control system based on microprocessors, designed with the principles of decentralized control, centralized operation and display, balanced functionality, and comprehensive coordination. DCS, short for Distributed Control System, can also be referred to as "distributed computer control system." It follows a multi-level hierarchical structure that emphasizes cooperative autonomy, combining centralized management with decentralized control.
Today, DCS systems are widely used across various industries such as power generation, metallurgy, and petrochemicals. Their reliability is crucial for continuous and safe operations. To ensure high reliability, three main strategies are commonly employed: the use of high-reliability hardware and advanced production technologies, the implementation of redundancy techniques, and the integration of fault-tolerant software, self-diagnosis, and automatic recovery features. Many modern DCS systems now have Mean Time Between Failures (MTBF) of tens of thousands or even hundreds of thousands of hours.
This article provides an overview of some of the leading DCS system manufacturers. Let's take a look at them.
