ABB 3BHL000986P3002 power supply
At the same time, DCS is no longer limited to the control of the main process unit system, but incorporates more auxiliary systems into the entire control system. ◆ Development of hardware technology: With the development of hardware technology, the hardware reliability of DCS systems has further increased. As the system scale continues to expand, the average time between failures (MTBF) of hardware has also remained above 100000 hours. Nowadays, DCS control stations generally use 32-bit processors and multiprocessor technology, and 64 bit processors have been introduced in the latest products. Compared with the 8-bit processors in the initial DCS control stations, the computing speed has been greatly improved. Application of advanced communication technology: From the perspective of communication, fieldbus has been widely used, and has been used in several recent large-scale petrochemical projects.
This article introduces the communication network of DCS and briefly explains the communication network of Bailey’s DCS used by our company. Keywords DCS I/O Bus Control Bus DCS Network 1 Preface DCS (Distributed Control System) is a control system based on microprocessors, characterized by hazardous decentralized control, centralized operation and management, and integrating advanced computer technology, communication technology, CRT technology, and control technology, namely 4C technology. With the rapid development of modern computer and communication network technology, DCS is moving towards diversification, networking, openness, and integrated management. This enables different models of DCS to be interconnected, exchange data, and connect the DCS system to the factory management network through Ethernet, achieving real-time data networking and becoming the mainstream of process industrial automatic control.
