Using Scada – An Overview and Facts About Scada

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.

A master control unit runs the Scada programs that can control and analyze the data from various equipments. There are many ways by which communication takes place between the master control unit and the various devices. Ethernet, radio links and modems are widely used for the purpose.

Due to the usage of diverse systems, many converters are employed for signal conversion for compatibility between various communication links. A central unit can control and monitor all the information received by various communication links.

All the information is stored in the central database. It is where all parameters of various equipments are continuously tracked and controlled. These can be modified if a read / write permission is provided to them. All the equipments located near or far, will have them monitored this way.

The SCADA program handles two types of parameters i.e. analog and digital. These are monitored and stored. The SCADA software processes them and interprets them in the way it is programmed.

The calculations made by SACA program can then help in supervisory control and data acquisition. Modern Scada software shows you a graphical representation of various objects on the computer screen.

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.

Additional software modules are available that will let you email or SMS yourself whenever a parameter passes a certain value. Thus SCADA systems can help maintain large scale plants having complex equipments.
