| Course Overview: |
Programmable logic controllers (PLCs) continue to evolve as new technologies are added to their capabilities. The PLC started out as a replacement for hardwired relay control systems. Gradually, various math and logic manipulation functions were added. Today PLCs are the controller of choice for the vast majority of automated processes. PLCs now incorporate smaller cases, faster CPUs, networking, and various Internet technologies.
This course provides a thoroughly practical introduction to the use of PLCs in industry, covering programming techniques alongside systems-level design issues. Topics include PLCs Overview, PLC Hardware, ladder logic diagrams, input/output modules, Program logic, surge protection, and selection/installation of controllers including relay ladder logic, numbering systems and codes, and programming timer. Series of real-world case will be studied to illustrate typical engineering challenges - and model solutions. Use of simulation software LogixPro 500 simulator. The course is supported by LogixPro simulation software converts the user’s computer into a PLC and allows the user to write ladder logic programs and verify their real-world operation.
