Interplay Learning - PLC Programming Introduction

Several types of programming languages have been developed to instruct and control the operation of Programmable Logic Controllers (PLC) in industrial settings. The PLC Programming Introduction course focuses on ladder logic, one of the more widely used programming languages. Using real-world examples, the course illustrates the use of ladder logic programs in controlling industrial automation tasks and electrical components. It covers essential concepts, symbols, and the structure of ladder logic programming, enabling learners to interpret ladder logic diagrams and follow the step-by-step execution of instructions, including logical operations, timers, and counters. With a look under the hood, learners will understand how internally, the PLC manages data files to organize information storage, assigns data types to variables for processing, and uses memory to store program data and operational states. Finally, a dedicated safety module covers the electrical hazards associated with PLC systems and emphasizes key safety practices.
