I need one experienced PLC engineer to join our commissioning crew on-site for roughly 15 consecutive nights (16:00–24:00). The equipment mix is a backlight-assembly machine paired with a roller-conveyor line, all driven by Keyence PLCs. What you’ll actually do • Take the partially written specifications we supply, fill the gaps, and build fully functional programs for both the backlight machine and the conveyor line. • Load, test and fine-tune those programs on the factory floor until the machines run to target cycle time and quality without alarms. • Work side-by-side with our existing commissioning team, but operate independently when required; I’m counting on your proven project experience to keep nightly progress on track. Key expectations • Deep, hands-on mastery of Keyence PLC hardware, ladder / structured programs, and associated HMI tools. • Confidence writing or refactoring complex logic from scratch when documentation is incomplete. • Clear, nightly hand-over notes so the day shift can see what was changed and why. Deliverable & acceptance A fully commissioned backlight assembly machine and roller conveyor line whose programs meet production specs, pass our site acceptance test without faults, and are handed over with final source files and concise documentation. If you are local, ready for night work and eager to dive straight into code and troubleshooting, I’d like to hear how soon you can start.
