A SCADA (Supervisory Control and Data Acquisition) system comprises various components that work together to enable industries to control industrial processes locally or at remote locations, monitor, gather, and process real-time data, and interact with devices such as sensors, valves, pumps, motors, and more through human-machine interface (HMI) software. Key components of a SCADA system include:
– Human-Machine Interface (HMI): Allows human operators to interact with the system.
– Supervisory System: The core of a SCADA system, which gathers data on the process and sends commands to the process.
– Remote Terminal Units (RTUs): Connect to sensors and actuators in the process, convert sensor signals to digital data, and send data to the supervisory system.
– Programmable Logic Controllers (PLCs): More rugged and versatile than RTUs, used for the same purposes.
– Communication Infrastructure: Enables the exchange of information between the supervisory system, RTUs, PLCs, and other devices.
Given this information, an option not listed above and therefore not a component of a SCADA system must be provided from the choices you have in mind, as I cannot see the options you are considering. Please specify the options, and I can then identify which is not a component of a SCADA system.
