Control operations įunctional levels of a manufacturing control operation It is one of the most commonly-used types of industrial control systems, in spite of concerns about SCADA systems being vulnerable to cyberwarfare/cyberterrorism attacks. They can control large-scale processes that can include multiple sites, and work over large distances as well as small distance. In practice, large SCADA systems have grown to become very similar to distributed control systems in function, while using multiple means of interfacing with the plant. The SCADA concept was developed to be a universal means of remote-access to a variety of local control modules, which could be from different manufacturers and allowing access through standard automation protocols. the real-time control logic or controller calculations, are performed by networked modules connected to the field sensors and actuators. The operator interfaces which enable monitoring and the issuing of process commands, like controller set point changes, are handled through the SCADA computer system. 8 Communication infrastructure and methods.
