2. Industrial control system - Wikipedia

   en.wikipedia.org/wiki/Industrial_control_system

   An industrial control system (ICS) is an electronic control system and associated instrumentation used for industrial process control. Control systems can range in size from a few modular panel-mounted controllers to large interconnected and interactive distributed control systems (DCSs) with many thousands of field connections.

3. Operational technology - Wikipedia

   en.wikipedia.org/wiki/Operational_Technology

   The term usually describes environments containing industrial control systems (ICS), such as supervisory control and data acquisition (SCADA) systems, distributed control system (DCS), remote terminal units (RTU) and programmable logic controllers (PLC), as well as dedicated networks and organization units. The built environment, whether ...

4. Instrumentation and control engineering - Wikipedia

   en.wikipedia.org/wiki/Instrumentation_and...

   Automatic control manages a device without the need of human inputs for correction, such as cruise control for regulating a car's speed. Control systems engineering activities are multi-disciplinary in nature. They focus on the implementation of control systems, mainly derived by mathematical modeling. Because instrumentation and control play a ...

5. Industrial process control - Wikipedia

   en.wikipedia.org/wiki/Industrial_process_control

   The fundamental building block of any industrial control system is the control loop, which controls just one process variable. An example is shown in the accompanying diagram, where the flow rate in a pipe is controlled by a PID controller , assisted by what is effectively a cascaded loop in the form of a valve servo-controller to ensure ...

6. Control system security - Wikipedia

   en.wikipedia.org/wiki/Control_system_security

   Control system security, or automation and control system (ACS) cybersecurity, is the prevention of (intentional or unintentional) interference with the proper operation of industrial automation and control systems. These control systems manage essential services including electricity, petroleum production, water, transportation, manufacturing ...

7. Control loop - Wikipedia

   en.wikipedia.org/wiki/Control_loop

   A control loop is the fundamental building block of control systems in general and industrial control systems in particular. It consists of the process sensor, the controller function, and the final control element (FCE) which controls the process necessary to automatically adjust the value of a measured process variable (PV) to equal the value of a desired set-point (SP).
