SCADASTANDS FOR:-SSUPERVISORY CCONTROL AANDDDATA AACQUISITION

SCADA enables ENGINEERS, SUPERVISORS, MANAGERS & OPERATORS to view & interact with the workings of entire operations through GRAPHICAL REPRESENTATION of their production process.

MEANING

• In other words SCADA can be explained as below:-

• SCADA refers to a system that collects data from various sensors at a factory, plant or in other remote locations and then sends this data to a central computer which then manages and controls the data.

WHAT IS DATA ACQUISITION?

• Data acquisition is the process of retrieving control information from the equipment which is out of order or may lead to some problem or when decisions are need to be taken according to the situation in the equipment. So this acquisition is done by continuous monitoring of the equipment to which it is employed. The data accessed are then forwarded onto a telemetry system ready for transfer to the different sites.

COMMON SOFTWARES OF SCADA

• Wonderware -- Intouch• Intellation -- Fix DMAC’s• Merz -- Aspic• Allen bradely -- Rsview• Siemens -- Win CC• GE Fange --Cimplicity

SCADA AS A SYSTEM

SUBSYSTEMS OF SCADA SYSTEM

• Human-Machine Interface is the apparatus which presents process data to a human operator, and through this, the human operator monitors and controls the process.

• Remote Terminal Units connecting to sensors in the process, converting sensor signals to digital data and sending digital data to the supervisory system.

• Programmable Logic Controller used as field devices because they are more economical, versatile, flexible, and configurable than special-purpose PLCs.

MAIN BENEFITS OF SCADA

• A rich functionality and extensive development facilities

• Reliability and robustness. These systems are used for mission critical industrial processes where reliability and performance are paramount

• Technical support and maintenance by the vendor

FEATURES OF SCADA

• ALARMS have a very critical role in automation.

Generally we have alarm states for each inputs/outputs.

• RECIPE MANAGEMENT When you have different products to

manufacture, you just have to load the recipe of the particular product.

• SECURITY You can allocate certain facilities or features to

the operator, process people, engineering dept and maintenance dept.

• DEVICE CONNECTIVITY SCADA software should have connectivity to

the different hardware used in automation

ADVANTAGES OF SCADA

• Long distance monitoring• Long distance training• Protection against terrorism/vandalism-alarm• Data management (engineering and

operations)• Automated operations with real time control

CONCLUSION

SCADA is a control system with● More interfaces and efficient storage● More record or device oriented configuration● But system wide configuration tools are

needed● finally various applications

WINDOWMAKER WINDOWVIEWER

InTouch Application Manager

WindowMaker Program Elements

• WindowMaker is the configurable development environment for InTouch.

• when you initially open WindowMaker, most of the available elements are automatically

• displayed including, all toolbars, the Application Explorer and the status bar.

The Application Explorer

• WindowMaker's Application Explorer is a hierarchical graphical view of your application.

The WindowMaker Toolbars

• The tools on the WindowMaker toolbars are grouped by common functionality.

General ToolbarThe General toolbar is grouped with tools that execute most of the window commandsfound on the File menu and the Microsoft Windows Clipboard tools found on the Editmenu: New Window Tool, Open Window Tool, Close Window Tool, Save Window Tool,Save All Tool, Duplicate Tool, Cut Tool, Copy Tool, Paste Tool, Undo Tool, Redo Tool,Print Tool

FORMAT TOOLBAR• The Format toolbar is grouped with tools that execute most of the text

object formatting• commands found on the Text menu. It also contains the tools you use to

access the color• palette to select line, text, fill, window background and transparent object

color (Font• Button, Bold Button, Italic Button,Underline Button, Reduce Font Button,

Enlarge Font• Button, Left Justified Button, Centered Button, Right Justified Button, Line

Object Color• Button, Object Fill Color Button, Window Color Button, Bitmap

Transparency Color• Button).

Draw Object Toolbar• The Draw Object toolbar is grouped with all the tools you use to draw

both simple• graphic objects such as rectangles, ellipses, lines or text objects and,

complex objects• such as real-time trends, historical trends, bitmaps and 3- dimensional

buttons with labels• in your windows (Selector Mode, Rectangle Tool, Rounded Rectangle

Tool, Ellipse Tool,• Any Angle Line Tool, Horizontal and Vertical Line Tool, Polyline Tool,

Polygon Tool,• Text Tool, Bitmap Tool, Real Time Trend Tool,, Historical Trend Tool,

Button Tool).

VIEW TOOLBAR

• The View toolbar is grouped with tools that execute most of the window commands found

• on the View menu. These commands are used to control the state of the WindowMaker

• window (Application Explorer Button, Hide All Button, Full Screen Button, Snap to Grid

• Button, Ruler Button).

The WindowMaker Color Palette

• The color palette appears whenever you click a colored square in a dialog box or, you

• click one of the color tools to apply line, fill or text color to a

selected object.
