SCADA: Supervisory Control and Data Acquisition.

SCADA: Supervisory Control and Data Acquisition.

1. Structural design

   • MicroProcessors
     • Programmable Logic Controllers or PLCs
     • Remote Terminal Units

2. BEFORE SCADA

   • plant personnel had to monitor
   • control industrial processes
   • selector switches
   • push buttons
   • dials for analog signals

3. Features

   • remote capabilities
   • automated communication
   • data transmission to remote monitoring locations

4. used for

   • monitoring
   • control of automated processes
   • Large scale automations

5. distributed SCADA systems

   • open system architectures
   • communication protocols
     • not vendor specific

6. networked SCADA system

   • Improved SCADA
     • didn’t last long
       • computer technology growing rapidly
       • IT development quickly gathered steam
       • SQL databases
       • SCADA developers didn’t implement standard databases
       • SCADA became out of date rather quickly

7. Current day SCADA systems

   • adapted to the changing technologies
   • Better than old SCADA Systems
     • adoption of modern IT standards
       • SQL
       • web-based applications
       • real-time
   • real-time information to be accessed from anywhere in the world
   • creating mandated record keeping
     • SQL database model
       • collected date used in trending applications
     • troubleshoot problems
     • Data Analysys
   • real-time data
   • communication protocol
   • Data collected from the field devices
     • passed to the processors such as PLCs
       • the data is distributed to a system of networked devices
         • HMIs
         • end user computers
         • servers
   • operator interactions
     • graphical representations
