    Study Notes

    History of Automation

    • Ancient Examples:
      • The Great Pyramids used basic forms of automation.
      • The Roman Empire used rudimentary flow meters in aqueducts.
      • In the 3rd century BC, the first true control device, a water clock valve, was invented.
    • Early Automation:
      • James Watt invented the flyball governor in 1772, still used to control steam engines.
      • The flyball governor is a simple mechanical device that controls the speed of a steam engine through centrifugal force and feedback loops.
    • Modern Automation's Beginnings:
      • Automation started taking off in the 1960s, driven by automotive manufacturing assembly lines.
      • Early automation relied on hardwired electrical and electromagnetic relays, allowing basic logical functions like AND, OR, and counting.
    • Programmable Logic Controllers (PLCs):
      • Modern PLCs evolved from the hardwired relay systems of the 1960s.
      • PLCs are small, versatile devices with CPUs, input/output cables, and sometimes ethernet and wireless connections.
      • PLC advancement stems from the early hardwired relay systems.
