Supervisory control is a general term for control of many individual controllers or control loops, such as within a distributed control system.It refers to a high level of overall monitoring of individual process controllers, which is not necessary for the operation of each controller, but gives the operator an overall plant process view, and allows integration of operation between controllers.
The supervisory control theory (SCT), also known as the Ramadge–Wonham framework (RW framework), is a method for automatically synthesizing supervisors that restrict the behavior of a plant such that as much as possible of the given specifications are fulfilled. The plant is assumed to spontaneously generate events.
SCADA (an acronym for supervisory control and data acquisition) is a control system architecture comprising computers, networked data communications and graphical user interfaces for high-level supervision of machines and processes.
One of his most important later works was his paper, “The Adaptive Reliability Control System" [6] which won an IEEE Power Group Prize Paper Award in 1968, [5] [7] earned him an IEEE Life Fellow [7] and the name "father of modern energy control centers". [2] He later became an independent consultant with the Dy Liacco Corporation, Cleveland ...
IEC 60870-5-101 [IEC101] is a standard for power system monitoring, control & associated communications for telecontrol, teleprotection, and associated telecommunications for electric power systems. This is completely compatible with IEC 60870-5-1 to IEC 60870-5-5 standards and uses standard asynchronous serial tele-control channel interface ...
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.

[3] When a German company has 500–2,000 employees, the workers select one-third of the supervisory board. [4] When it comes to internal elections the chairman of the supervisory board, the Aufsichtsratsvorsitzender, has two votes in case of a draw. [5] The supervisory board, in theory, is intended to provide a monitoring role. However, the ...
