2. SCADA
• SCADA is majorly availed in processes of an industry for superior control and
data acquisition.
• SCADA stands for Superior Control and Data Acquisition.
• It can be used for controlling ancillary systems like power distribution, cooling,
ventilation etc.
• systems of SCADA made high progress in expressions like openness,
performance, scalability, functionality.

7. Architecture
Hardware architecture:
• SCADA system contains two important layers and those are client layer and
data server layer.
• Client layer contributes in man machine interaction and coming to data
server layer then it handles activities of process data control.
• Exchange of information between data servers and machines in the field is
done through process controllers.
• A connection between data servers and client stations is done through an
Ethernet LAN.

8. Typical Hardware Architecture

9. Software architecture
• It contains multi-tasking products which are based upon RTDB i.e. real-time data
base.
• Servers perform tasks like data acquisition and handling.
• For example, tasks which come under data acquisition and handling are logging,
archiving, calculations, alarm checking, and polling controllers.

10. Software architecture does the following
communications
• Internal communication
• Access to devices
