All the SCADA systems irrespective of field where they implied rely on same principle. These systems are employed for remote management of critical processes.

These systems have central room/system to manage all these processes with the help of computers and communication networks. The remote sensors collect the data at specific interval of time which is predefined and then sends this data to central system which processes the data collected.

Thus, main components of SCADA system can be zeroed into three components: Hardware (for input and output), PLCs (Programmable Logic Converters, which determines the responses SCADA system issues when some error is detected) and Transmission media (through which data collected is sent to central system through remote terminals). Though various modes of media are used like Ethernet, internet or wireless but radio transmission has always been cost effective solutions.

There are specific buttons which are associated with certain buttons and in a moment of time with the interplay of these buttons, you can generate your SCADA screens. Moreover, some software allow drag and drop feature for OPC tags from OPC server directly either via Internet or Ethernet.

One should take best care while developing SCADA screens as the main purpose of these screens is to monitor the data in a real time and any major/minor mistake in creation of screen can play havoc with the output and your whole design can go astray as over representation/ under representation of any type of one parameter can lead to fallacious results.

Also, one should not be hesitant in using software for creating of screens as they make the task of creation of error free pretty easy and one can monitor the data live.

SCADA systems, acronym for Supervisory Control and Data Acquisition systems are supervisory systems that have made automated tasks more reliable and efficient without having need of human to intervene or handle any stage of process.

Thus, SCADA systems are also known as closed loop systems as they operate of their own and response to change in parameter value/ state beyond permissible values. Also, there is always a possibility of human intervention as per the need that provides flexibility to SCADA systems. Due to high range of flexibility, reliability and efficiency SCADA systems have found their applications in control systems (electricity control systems, water sewerage systems), radio transmissions (long distance Scada GSM).

Even daily routine equipments have not left untouched by this tremendous technology and many SCADA compatible equipments like water metering pumps have flooded markets.
