Course Description:

This is a basic to intermediate course in programmable logic controllers.  The focus of the training is on Allen Bradley Micrologix PLCs along with RSLogix500 software.

The concepts covered in the basic portion (Days 1-2) of the course include:

Inputs and Outputs – Field Devices and Operators
Addressing
Ladder Logic/PLC Programming
Momentary Inputs/Outputs
Latching and Unlatching Inputs/Outputs
Reading and Writing Programs in LogixPro Simulation Software
Counters
Timers

The systems utilizing these newly learned concepts are designed and tested using the LogixPro simulation software.  This program very closely simulates real-world PLC programming, and interactive animations give student feedback for troubleshooting problems with programs.

The intermediate (applications) portion (Days 3-5) of the course is a very hands-on setting, concentrating almost exclusively on real world applications.  During this time, students move up from the LogixPro simulator to the fully functional Rockwell RSLogix500 software. 

Students are given various control applications for which they write a PLC program using digital inputs and outputs.  These applications include tank level control, part sensing on a conveyor, and temperature sensing and control to name just a few.  These programs are then downloaded to actual control stations on site to test and view their programs in action. 

On the final day, students complete a capstone project involving a three level lift system.  This involves programming and testing a control system designed for what is in effect an elevator for a three story building.
