Industrial40 Questions and AnswersFreeUpdated Sep 2026
This flashcard set covers automation engineering systems, the discipline of designing, building, and maintaining machines and processes that run with little or no human intervention. You will review how automation evolved from fixed mechanical control to flexible programmable systems, how sensors and actuators connect a process to its controller, how programmable logic controllers execute logic, how feedback loops keep variables near their targets, and how networks, human machine interfaces, and safety functions tie an entire plant together.
Study each group in order, because later cards assume the vocabulary of earlier ones. Read each question aloud, answer it in your own words before reading the card, and then compare your response. Pay attention to the first sentence of each answer, which states the core idea, and use the remaining sentences to add conditions and examples. Sketch simple block diagrams whenever a card describes a signal path, since drawing the loop or network often makes the relationships clearer. Review missed cards daily until you can explain each concept without notes.
