Converters and on its basis the system reacts to a particular state. PLCs can be easily programmed. The SCADA system like in all systems also keeps a record of data collected in database in a systematic way and can be easily accessed and manipulated.

Thus, when one needs to locate the fault he can easily locate by checking the parameters which are stored in database. As the faults gets detected in a timely and efficient manner, SCADA in the water industry also saves troubleshooting costs which can be huge if there is no idea of the location f the fault.

Data transmitted from remote sensors to central unit can be done in many ways (Ethernet, serial ports, wireless) but wireless mode of transmission is always cost effective and efficient. Thus, it can be concluded that SCADA in the water industry has proved to be a boon paying for the efficient and reliable working of water control systems.

SCADA stands for Supervisory Control and Data Acquisition. SCADA can be thought of as a system which is designed to collect data from the sensors located in remote locations, such as various areas of a plant, factory or at any other remote location and then sending the data collected to a main computer which controls and manages the data.

SCADA has finds its application in wide range of industries from electric power, water management systems, environmental control systems, mass transportation or manufacturing systems.

A SCADA system can be divided into following parts: Signal hardware (for both output as well as input), controllers, user interface (also known as HMI), networks, and software along with communication equipment. In general, SCADA means entire system with the common goal to collect, manage and control the data.

All SCADA systems work on one principle. Remote sensors collect data and central system processes them. The central system stores data which can be analysed at a later stage and is known as SCADA Historian data analysis.

The analysed data is presented in human readable format at Man Machine Interface, often abbreviated as MMI. These tasks are performed with special software. The record which gets collected on hourly basis (or any predefined period) is scrutinized as well as SCADA Historian data analysis is undertaken with the purpose of process optimization. For SCADA Historian data analysis to be carried out the main requisite is existence of database as it is acts as repository for processing of data.

The applications for SCADA Historian data analysis are generally written in either VB or Microsoft C and the data is entered into database either manually or through the remote sensors. Generally, the software creates time sampled records which can be easily scrutinized with the purpose of process optimization. The reports generated are either event based (report is generated on occurrences of particular event) or time based (report is generated every hour).
