Distributed Control System


A distributed control system is a control system for a process or plant, wherein control elements are distributed throughout the system. This is in contrast to non-distributed systems, which use a single controller at a central location. In a DCS, a hierarchy of controllers is connected by communications networks for command and monitoring. We offers multiple automation and control strategies, architectures, and solutions for every application size and complexity.

Key Feature

  • Improves reliability and minimizes failures by distributing the control functions to each mini-system
  • Centralizes the distributed systems for efficient data processing and operation management
  • Servers and clients. The servers gather tag data from the PLC(s), contain the graphics, and serve both out to clients for operators to use.
  • Redundant servers, controllers and/or networks.
  • Synchronized alarming and security.
  • Historical data logging and trending.
  • Batch management.
Example scenarios where a DCS might be used include:
  • Chemical plants
  • Petrochemical (oil) and refineries
  • Boiler controls and power plant systems
  • Nuclear power plants
  • Environmental control systems
  • Water management systems
  • Pharmaceutical manufacturing
