SCADA systems have traditionally used combinations of radio and direct wired connections, although SONET/SDH is also frequently used for large systems such as railways and power stations. The remote management or monitoring function of a SCADA system is often referred to as telemetry. Some users want SCADA data to travel over their pre ...
Remote monitoring and control (M&C) systems are designed to control large or complex facilities such as factories, power plants, network operations centers, airports, and spacecraft, with some degree of automation. M&C systems may receive data from sensors, telemetry streams, user inputs, and pre-programmed procedures.
The Vision module is one of the two main visualization modules of the Ignition SCADA platform. The Ignition Vision Runtime or Client is a Java application typically launched as an application on a client computer. It acts as the HMI interface for end users and can be used to view realtime or historical process data or control industrial ...
However, the development of SCADA (supervisory control and data acquisition) systems allowed remote control and monitoring of electrical plant from centralised control centres. Initially individual SCADA manufacturers developed their own proprietary "closed" protocols for communicating from a control centre to electrical equipment in the field.
Supervisory control and data acquisition (SCADA) is a control system architecture that uses computers, networked data communications and graphical user interfaces for high-level process supervisory management. The operator interfaces which enable monitoring and the issuing of process commands, such as controller setpoint changes, are handled ...
The computer technology is also referred to as SCADA/EMS or EMS/SCADA. In these respects, the terminology EMS then excludes the monitoring and control functions, but more specifically refers to the collective suite of power network applications and to the generation control and scheduling applications.
It also offers a cloud architecture serving SCADA, EMS, GMS, DMS and other smart-grid products such as demand response, renewables management, volt/VAR control and asset monitoring applications. [6] OSI systems manage nearly 20 percent of the world's energy supply, transport and delivery. [7]
The Sangamon Valley Public Water District [3] (SVPWD) in Mahomet, Illinois, implemented FreeWave radios in a new SCADA system to communicate with remote wells and control equipment and settings from a central location rather than sending personnel to collect data and monitor the water system. SVPWD reported 50 percent cost savings, with savings ...
