Systems concepts The term SCADA usually refers to centralized systems which monitor and control entire sites, or complexes of systems spread out over large areas anything between an industrial plant and a country. Host control functions are usually restricted to basic overriding or supervisory level intervention.
Ex: A PLC may control the flow of cooling water through part of an industrial process, but the SCADA system may allow operators to change the set points for the flow, and enable alarm conditions, such as loss of flow and high temperature, to be displayed and recorded.
Data is then compiled and formatted in such a way that a control room operator using the HMI can make supervisory decisions to adjust or override normal RTU PLC controls. Data may also be fed to a Historian, often built on a commodity Database Management System, to allow trending and other analytical auditing. A point represents a single input or output value monitored or controlled by the system. Points can be either "hard" or "soft". A hard point represents an actual input or output within the system, while a soft point results from logic and math operations applied to other points.

Most implementations conceptually remove the distinction by making every property a "soft" point expression, which may, in the simplest case, equal a single hard point. Points are normally stored as value- timestamp pairs: a value, and the Time-Stamp when it was recorded or calculated.
A series of value- timestamp pairs gives the history of that point.
It's also common to store additional metadata with tags, such as the path to a field device or PLC register, design time comments, and alarm information. Human Machine Interface A Human Machine Interface or HMI is the apparatus which presents process data to a human operator, and through which the human operator controls the process.
An HMI is usually linked to the SCADA system's Database and software programs, to provide trending, diagnostic data, and management information such as scheduled maintenance procedures, logistic information, detailed schematics for a particular sensor or machine, and expert-system troubleshooting guides.
The HMI system usually presents the information to the operating personnel graphically, in the form of a mimic diagram. This means that the operator can see a schematic representation of the plant being controlled. For example, a picture of a pump connected to a pipe can show the operator that the pump is running and how much fluid it is pumping through the pipe at the moment.
The operator can then switch the pump off. The HMI software will show the flow rate of the fluid in the pipe decrease in real time. Mimic diagrams may consist of line graphics and schematic symbols to represent process elements, or may consist of digital photographs of the process equipment overlain with animated symbols.
The HMI package for the SCADA system typically includes a drawing program that the operators or system maintenance personnel use to change the way these points are represented in the interface.
These representations can be as simple as an on-screen traffic light, which represents the state of an actual traffic light in the field, or as complex as a multi-projector display representing the position of all of the elevators in a skyscraper or all of the trains on a railway.
The system monitors whether certain alarm conditions are satisfied, to determine when an alarm event has occurred. Once an alarm event has been detected, one or more actions are taken such as the activation of one or more alarm indicators, and perhaps the generation of email or text messages so that management or remote SCADA operators are informed.
In many cases, a SCADA operator may have to acknowledge the alarm event; this may deactivate some alarm indicators, whereas other indicators remain active until the alarm conditions are cleared.
Alarm conditions can be explicit - for example, an alarm point is a digital status point that has either the value NORMAL or ALARM that is calculated by a formula based on the values in other analogue and digital points - or implicit: the SCADA system might automatically monitor whether the value in an analogue point lies outside high and low limit values associated with that point.
Examples of alarm indicators include a siren, a pop-up box on a screen, or a coloured or flashing area on a screen that might act in a similar way to the "fuel tank empty" light in a car ; in each case, the role of the alarm indicator is to draw the operator's attention to the part of the system 'in alarm' so that appropriate action can be taken.

In designing SCADA systems, care is needed in coping with a cascade of alarm events occurring in a short time, otherwise the underlying cause which might not be the earliest event detected may get lost in the noise. Unfortunately, when used as a noun, the word 'alarm' is used rather loosely in the industry; thus, depending on context it might mean an alarm point, an alarm indicator, or an alarm event.
By converting and sending these electrical signals out to equipment the RTU can control equipment, such as opening or closing a switch or a valve or setting the speed of a pump. In larger SCADA systems, the master station may include multiple servers, distributed software applications, and disaster recovery sites.
To increase the integrity of the system the multiple servers will often be configured in a dual-redundant or hot-standby formation providing continuous control and monitoring in the event of a server failure.
Operational philosophy For some installations, the costs that would result from the control system failing are extremely high. Possibly even lives could be lost. Hardware for some SCADA systems is ruggedized to withstand temperature, vibration, and voltage extremes, but in most critical installations reliability is enhanced by having redundant hardware and communications channels, up to the point of having multiple fully equipped control centres.
A failing part can be quickly identified and its functionality automatically taken over by backup hardware. Uploaded By BaronStarOkapi Rajendra Prasad E.
Rajendra Patel A. I am very grateful to the whole Control and Instrumentation Department for their support and guidance. I am also very thankful to the workers and employees near the machineries and the library in charge for their support to my training. The report was made under my supervision, and I express my delight on it successful completion.

I am also very happy to have offered her guidance whenever it was required. Then I would like to thank the faculty members at the institute Mr. Sarukh Patel, Mr. Vishal and Mrs.
Komal for their sole devotion in teaching us. The valuable guidance and interest taken by them has been a motivator and source of inspiration for me to carry out the necessary proceedings for the training to be completed successfully.
ABSTRACT Automation is the use of machines, control systems and information technologies to optimize productivity in the production of goods and delivery of services.Allows a specific colour to be set for the normal state as well as a separate colour for each alarm condition defined for the tag name.
Almost any production line, machine function, or process can be greatly enhanced using this type of control system.
When "solved" if the coil is a logical 0, power will be turned on to the device. For example, a picture of a pump connected to a pipe can show the operator that the pump is running and how much fluid it is pumping through the pipe at the moment. These pins each are dedicated to a specific purpose. The supermarket was the external device where I got the data tv dinners from and my microwave is the plc.
