Abstract
PLC programs provide precise control over machinery and industrial processes. They dictate how equipment operates, ensuring tasks are performed accurately and consistently according to predefined parameters. In this project, I create the PLC program for a Mitsubishi PLC and design the HMI screen template using Mitsubishi HMI software for a vision checking system integrated with linear servo motorsTop of Form. In vision checking system with linear servo motors inspects PCBA and wiring using a vision camera moved by a servo gantry system. Safety measures are implemented. The program includes auto, manual, and homing sequences, along with mode selection, error handling, counter, shift, and tower lamp functions. HMI screens are designed to teach machine operation. In auto mode, servos move to positions set in the HMI recipe screen. Manual mode allows servo jogging and movement between positions via the HMI servo screen. Pressing the homing button moves servos to user-set home positions. Safety measures, including light curtains, door switches, and fixture sensors, halt the machine and sound a buzzer in case of errors. Counter and shift programming displays running shift and component counts. Programs are tailored to input/output device operations. Key Words: PLC Programming, HMI Screen designing.
