Introduces students to programmable logic controllers (PLCs) using IEC 61131-3 languages, with emphasis on ladder logic and early exposure to structured text and function block diagrams. Topics include input and output hardware, timers, counters, state machines, safety interlocks, and basic HMI development. Labs with Rockwell and Siemens platforms culminate in programming and debugging an automated station with sensors, actuators, and operator controls. Prereq: CSCI 160 and MATH 146.
