SCADA stands for Supervisory Control And Data Acquisition and refers to a system that collects data from remote locations and sends it to a central computer for management and control. Data acquisition involves continuously monitoring equipment to retrieve control information and identify potential problems. SCADA systems are used across infrastructure, industrial, and facility processes. They have a hierarchical structure with remote terminal units collecting data at remote sites, programmable logic controllers acting as field devices, and human-machine interfaces allowing operators to monitor and control the process from a central location.

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. 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.

4. TYPES OF PROCESSES

5. INFRASTRUCUTRE PROCESSES
• Telecommunications
• Transportation
• Water and Waste Control

6. INDUSTRIAL PROCESSES
• Manufacturing/Production
• Quality Control
• Maintenance

7. FACILITY PROCESSES
• Oil and Gas
• Electricity/Power

8. SCADA HIERARCHIAL LAYERS

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. PLCs vs RTUs
PLCs used as field devices because:
• more economical
• versatile
• flexible
• configurable

11. HMI
• Presents process data to a human
operator
• operator monitors and controls the process
from here
• Master device
