Data acquisition and supervisory control indicates industrial control systems, which are utilized to control as well as keep track of a plant or equipment in industries like waste and water control, energy, telecommunications, oil and gas refining and transport. SCADA is a type of computer system employed to analyze and collect real time data. Computer processes this data and is offered on regular basis. SCADA make and also saves logs for each event into log file which is saved on hard drive or transferred to a printer. SCADA offers warnings by activating alarms when situations create hazardous scenarios. SCADA Systems comprise of field data interface equipment normally remote control units or programmable logic controllers.SCADA system also consist of communications system, which is used to move data between various pieces of control units and field data interface device and the computer systems used in SCADA central host. Systems may be radio, telephone, cable, satellite and a blend of any of those.
The telecommunication network is crafted to deliver the way by which data can be sent in between central host computer servers and field-based RTUs. SCADA includes central host computer servers, which is usually known as a SCADA center, master station or a master terminal unit. Central host computer is normally a computer server network or a single computer. There is a set of customized software systems or a set of standard that are helpful in offering the SCADA central host and operator terminal application. This supports communication systems and controls and monitors the remotely placed field data interface tools. Some of the software products normally used within SCADA system include central host computer, operator terminal OS, operator terminal application, central host computer application, RTU automation software, communications protocol drivers and software of communications network management. |
