Distributed Control Systems (DCS) are plant-wide control platforms designed for continuous and batch processes where high availability and standardized engineering are critical. A typical architecture includes redundant controllers, distributed I/O, operator workstations, engineering stations, historians, and an industrial network linking controllers to field devices and supervisory layers. Technical characteristics often include redundancy options, time-synchronized data, secure segmented communications, extensive diagnostics, and configuration databases for logic, alarms, and graphics. Functional capability includes loop control, advanced alarm management, batch sequencing, interlocks, and integration with third-party instrumentation and drives. For connectivity hardware and protocol gateways that support DCS networks, reference Communication & Networking. For process power distribution components used around control cabinets, see Power & Electrical Components.
