  2. Distributed control system - Wikipedia

    en.wikipedia.org/wiki/Distributed_control_system

    A distributed control system (DCS) is a computerized control system for a process or plant usually with many control loops, in which autonomous controllers are distributed throughout the system, but there is no central operator supervisory control. This is in contrast to systems that use centralized controllers; either discrete controllers ...

  3. SCADA - Wikipedia

    en.wikipedia.org/wiki/SCADA

    In smaller SCADA systems, the supervisory computer may be composed of a single PC, in which case the HMI is a part of this computer. In larger SCADA systems, the master station may include several HMIs hosted on client computers, multiple servers for data acquisition, distributed software applications, and disaster recovery sites.

  4. Industrial control system - Wikipedia

    en.wikipedia.org/wiki/Industrial_control_system

    The boundaries between DCS and SCADA/PLC systems are blurring as time goes on. [9] The technical limits that drove the designs of these various systems are no longer as much of an issue. Many PLC platforms can now perform quite well as a small DCS, using remote I/O and are sufficiently reliable that some SCADA systems actually manage closed ...

  5. Process control network - Wikipedia

    en.wikipedia.org/wiki/Process_control_network

    Determinacy involves assuring that each device is guaranteed access to the network, and in many cases mechanisms to allow priority information (such as alarms) through the system. Compatibility allows SCADA and Distributed Control Systems (DCS) from various manufacturers to communicate with control and measurement equipment from others.

  6. Industrial process control - Wikipedia

    en.wikipedia.org/wiki/Industrial_process_control

    A programmable logic controller (PLC, for smaller, less complex processes) or a distributed control system (DCS, for large-scale or geographically dispersed processes) analyzes this sensor data transmitted to it, compares it to predefined setpoints using a set of instructions or a mathematical model called the control algorithm and then, in ...

    en.wikipedia.org/wiki/Outline_of_automation

    Control system – a device, or set of devices to manage, command, direct or regulate the behavior of other devices or systems.; Industrial control system (ICS) – encompasses several types of control systems used in industrial production, including supervisory control and data acquisition (SCADA) systems, distributed control systems (DCS), and other smaller control system configurations such ...

  8. Remote terminal unit - Wikipedia

    en.wikipedia.org/wiki/Remote_Terminal_Unit

    A remote terminal unit (RTU) is a microprocessor-controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system to control connected objects. [1]
