Industrial real estate Scada Programs - Overview and Basic Facts
Scada programs are being extensively used for controlling complex equipments and whole plants. From SCADA, we mean Supervisory Control and Data Acquisition. It is in use for various complex systems and uses highly advanced man machine interfaces.SCADA programs are run on computers and are used to control various devices from there. Many techniques are used to link to the devices that have to be controlled. These include Ethernet, modems and radio links. Sensors are used to access data about various devices in a plant or industrial location.Various communication interfaces are used due to which the data is transmitted in various forms. Thus converters have to be used for conversion of data. All the information reaches the central unit where it is processed and analyzed regularly.A central database is maintained. Various parameters of the SCADA controlled instruments can be accessed and these can also be changed if there is a read / write permission for a device. So the central database and master unit help control various parameters of instruments.There are two types of parameters used. These are analogue or digital. The SCADA software fetches them continuously and stores them. The program can then makes its calculations based on all those stored parameters.Then the results obtained after making calculations are interpreted graphically. These are then shown on the computer screen as bars and charts. All this helps SCADA maintain its supervisory control easily.Some of the parameters received from various equipments are temperature, pressure and liquid level. The scada software can show the measurements and parameters in terms of graphical objects on the computer screen.The scada pc software can also have additional modules that will automatically SMS or email a person during any problem or a pre-programmed situation. Thus these can help control a plant and access information about it remotely.
