Supervisory Control and Data Acquisition, or SCADA for short, describes a computer system that monitors and controls technical processes in automated manufacturing.
SCADA utilizes measurement data from the lower levels of the automation pyramid and thus enables manual or automated adaptation of the processes to the target parameters.
SCADA systems often communicate via modern Internet transmission techniques (TCP). In the local exchange area, however, it is still possible to have them communicate using a point-to-point connection.
A SCADA system often consists of various and individual requirements of adapted hardware and software components, such as: programmable logic controllers (PLC) and remote control terminals (RTU). Several technologies are provided by the SCADA system. This results in a system that collects data in real time, monitors it and processes it.
