PLC Fundamentals

Service Description

Level 1 PLC Fundamentals Prerequisites: Basic Electrical Wiring Knowledge and Introduction to PLC's Course Length: 3 days Textbook: Introduction to Programmable Logic Controllers This course covers the fundamentals and principles of Industrial Programmable Logic Controllers (PLC's). The focus is on PLC functionality, hardware, and software; and practical information on maintaining PLC systems. Students will examine the control of systems with a PLC simulator and laptops. Emphasis will be on using the PLC as a diagnostic tool for troubleshooting the processing system.
