DCS
DCS, or Distributed Control System, is like a central brain that helps run large manufacturing plants, especially in chemical production. Think of it as a sophisticated control room system that lets operators monitor and control various parts of the production process from computer screens. Instead of having workers manually check each machine or valve, DCS allows them to manage everything from a central location, making the plant safer and more efficient. Similar systems include PLC (Programmable Logic Controller) and SCADA (Supervisory Control and Data Acquisition), but DCS is typically used in larger, more complex facilities.
