PLC Troubleshooting I

This is a comprehensive hands-on program that features simulations, lab activities with hardware components and basic PLC programming activities.
The successful participant will receive rigorous training on the internal workings of a PLC including solid-state switching and opto-isolation, analog and digital signal processing, ladder logic control programs and memory allocations. The activities completed demystify the workings of PLCs and their related input and output processes. In addition, a PLC simulation software package will be used that closely mimics popular brands of PLC software while presenting a visual layout and animation of actual manufacturing and process machinery which trainees use to complete their application exercises.
The program concludes with comparisons of popular PLC’s such as Allen Bradley and Siemens. The concept of using the PLC’s software as a basic troubleshooting tool will be introduced.
