  1. 1. SCADA
  2. 2. WHAT IS SCADA?• SCADA stands for Supervisory Control And Data Acquisition.• SCADA refers to a system that collects data from various IO signals 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.
  3. 3. WHAT IS DATA ACQUISITION?• Process of retrieving control information from  the equipment which is out of order or may  lead to some problem. • Continuous monitoring of the equipment to  which it is employed. • Data accessed forwarded onto a telemetry  system ready for transfer to the different  sites.

  5. 5. INFRASTRUCUTRE PROCESSES• Telecommunications• Transportation• Water and Waste Control
  6. 6. INDUSTRIAL PROCESSES• Manufacturing/Production• Quality Control• Maintenance
  7. 7. FACILITY PROCESSES• Oil and Gas• Electricity/Power
  8. 8. SCADA HIERARCHIAL LAYERS
  9. 9. RTU• Short for remote terminal unit• Installed at remote location• Collects data, codes the data into a format that is transmittable• Transmits the data back to a master• Collects information from the master device and implements processes that are directed by the master.• Input channels for sensing or metering• Output channels for control, indication or alarms• Communications port.
  10. 10. PLCs vs RTUsPLCs used as field devices because:• more economical• versatile• flexible• configurable
  11. 11. HMI• Presents process data to a human operator• operator monitors and controls the process from here• Master device
