Powder Coat Reprogram

The purpose of this project was to upgrade the control system for a Power and Free Overhead Conveyor System that transports forklift mast components through a powder coat painting process. The system was re-programmed such that improvements could be made to the logic and to match a programming style of the Main Paint Line. The program was installed and tested across a 2-day weekend.
