SCADA stands for Supervisory Control and Data Acquisition. It is a system of hardware and software elements that work together to allow industrial organizations to control industrial processes locally or at remote locations. The primary purpose of SCADA systems is to monitor and control processes in real-time, enabling operators to make informed decisions and adjustments. SCADA systems collect data from various sensors and instruments in the field. Data can include information about temperature, pressure, flow rates, and other relevant parameters. SCADA systems rely on communication networks to transmit data between the central system and remote field devices. Common communication protocols include Modbus, DNP3, and OPC.
