Various sensors get data from different equipments and send it over communication channels to the central master unit. The SCADA system handles all that data and analyzes all the equipments working in the factory.
The most complex industrial plants use the scada software to mange their complex equipments. There are various input output channels used. They are several hundred thousands in number. All the parameters from hundreds of equipments are managed by Scada systems.
Scada system becomes complete with the support of various other components. Some of them are HMI interfaces, controllers and remote interfaces. The information from various equipments has to be supplied to the main computer.
The main computer is called master terminal unit. In addition to it, there are many remote terminal units that are also connected to the master unit via various links. The remote units gather data from remote devices.
Distributed Control Systems (DCS) are used in factories for control and data acquisition. These are used for confined locations and data is communicated via LANs. Closed loop control is used in such environments.
Unlike the above locations, open loop control is used in scada systems. There may be few cases where closed loop is also used but it is rare. Not all communication links are established over LAN here. The control devices are also not confined to small areas.
There are often windows in software code that are often exploited by hackers propelled by various objectives. Power infrastructure is one such vulnerable place that has to be protected from Chinese or Russian hackers. Penetration testing can minimize these problems to a big extent.
The software and hardware used in supervisory control are monitored and tested for any windows that can be exploited by hackers. The communication is also monitored. Penetration testing is very important for security purposes. - 30201
