DCS
DCS (Distributed Control System) is like a central brain that helps run large industrial facilities such as factories, power plants, or refineries. Think of it as a sophisticated control room system that allows operators to monitor and control various equipment and processes throughout a facility from computer screens. Unlike simpler control systems, a DCS spreads its control capabilities across multiple locations in the facility while keeping everything connected. It's similar to how a shopping mall has different stores but is managed from one central office. Other names for similar systems include Process Control System (PCS) or Industrial Control System (ICS).
