What is Understanding Programmable Logic Controllers about?
This document provides an overview of programmable logic controllers (PLCs). It discusses that PLCs were introduced in the late 1960s to replace relay-based automation systems. The major components of a PLC include a power supply, input/output modules, a processor, and a programming device. PLCs operate through a sequence of input scanning, logic solving, and output scanning. Ladder logic is described as the most common programming language for PLCs using contacts, coils, and logic gates. An example ladder
