Auntie CeCe's PLC Basics Course: What a PLC Is & How It Thinks | Part 1

Part 1 of 5 in Auntie CeCe's PLC Basics Course, with animated diagrams on every card. In this lesson: Welcome, My Dear; From Relays to PLCs; Parts of a PLC; Inputs and Outputs; Discrete and Analog Signals; The Scan Cycle; Bits, Words and Addresses; Your First Rung; Real Machine: A Conveyor; PLC Programming Languages; Auntie's Recap. Ends with a 3-question quiz (pause and work it out) and the answers. This course gives general training only. Always follow the PLC and machine manufacturer's manuals, your site's lockout/tagout procedures, and local electrical codes (NEC/NFPA 79 in the US). Never rely on a standard PLC alone for safety functions; emergency stops and guarding need safety-rated devices designed and validated by qualified people. Instruction names and addresses follow Allen-Bradley style; other brands differ. #AuntieCeCe #PLC #Training
