- 4. Why SCADA?Why SCADA? Previously without SCADA an industrialPreviously without SCADA an industrial process was entirely controlled by PLC,process was entirely controlled by PLC, CNC , PID & microcontrollers havingCNC , PID & microcontrollers having programmed in certain languages orprogrammed in certain languages or codes.codes. These codes were either written inThese codes were either written in assembly language or relay logic withoutassembly language or relay logic without any true animation that would explain theany true animation that would explain the process running.process running.

SCADASCADA In the left side you see the ladder program which is written forIn the left side you see the ladder program which is written for PLC and on the right side is the process for which the logic isPLC and on the right side is the process for which the logic is written.written. Now we can easily understand the process if it is shown withNow we can easily understand the process if it is shown with some animations rather then written codes.some animations rather then written codes. Hence SCADA came to exist and with this it brought someHence SCADA came to exist and with this it brought some exclusive features that amazed the industrial people.exclusive features that amazed the industrial people. SCADA related to industrial process is called industrial SCADA.SCADA related to industrial process is called industrial SCADA.

Understanding SCADAUnderstanding SCADA It works like a supervisor who supervises the entire plantIt works like a supervisor who supervises the entire plant area ,if needed it also controls the process as well itarea ,if needed it also controls the process as well it converts the data segments for storing process valuesconverts the data segments for storing process values i.e. level , pressure , switch positions , density ,i.e. level , pressure , switch positions , density , temperature, messages , etc.temperature, messages , etc. From a distant place if we want to run the process i.e.From a distant place if we want to run the process i.e. starting , stopping , opening and closing of fieldstarting , stopping , opening and closing of field instruments as well logging the various values. SCADAinstruments as well logging the various values. SCADA can do for you.can do for you. SCADA is not a 100% controller it is just a softwareSCADA is not a 100% controller it is just a software which has to be linked with controllers. ultimately it haswhich has to be linked with controllers. ultimately it has to connected to PLC / PID / DCS systems which in turnto connected to PLC / PID / DCS systems which in turn are connected to field instrumentsare connected to field instruments..

How is SCADA connectedHow is SCADA connected SCADA is installed in the computers andSCADA is installed in the computers and through serial port it is linked to PLC .through serial port it is linked to PLC . All the field devices are connected to PLCAll the field devices are connected to PLC and they get signals or commands from PLC.and they get signals or commands from PLC. Whatever applications we want to run can beWhatever applications we want to run can be executed either through PLC or SCADA.executed either through PLC or SCADA.

ALARMSALARMS In the field area alarms are generated forIn the field area alarms are generated for warnings or to keep the process betweenwarnings or to keep the process between certain limits.certain limits. Generally these alarms are implemented byGenerally these alarms are implemented by indicating lamps or Hooters in field butindicating lamps or Hooters in field but SCADA represents it with a format.SCADA represents it with a format. The format consists of date , time , status ,The format consists of date , time , status , priorities , many such elements which canpriorities , many such elements which can be used for generation of reports.be used for generation of reports.
- 14. TRENDSTRENDS These are also called as XY plotters or DataThese are also called as XY plotters or Data loggers. Basically it represents the values inloggers. Basically it represents the values in wave formats .It is one of the important featurewave formats .It is one of the important feature of SCADA.of SCADA. It plots the value with reference to time.It plots the value with reference to time. Trend is subdivided into real time and historicalTrend is subdivided into real time and historical trends. i.e. we can see the present values oftrends. i.e. we can see the present values of the process as well past values and can bethe process as well past values and can be stored and records can be maintained for thestored and records can be maintained for the same.same.
- 15. SCRIPTSSCRIPTS • It is the combination of logical operators which are written in a statement. • It is used to run the applications made or stimulate before final execution. • Various types of scripts make project execution simpler for programmer.
- 16. SECURITYSECURITY • Every application has to be secured from unauthorized users by different security levels . • In SCADA this security can be given as a whole as well as individually.
- 17. RECIPE MANAGEMENTRECIPE MANAGEMENT • One of the finest feature of any SCADA . • It explains that we can maintain various recipes of different process and implement it on the process. • All the recipes are stored in a single server and it can be fetched by any client server from any area to run the process.
