I need the logic inside my Schneider Modbus controller refreshed. At the moment the system relies on pressure sensors that scale from 0-70; that scale must be expanded to 0-100 and reflected everywhere the readings drive valve operation. Once the new range is in place, I want to refine the existing ladder/structured-text so the valves respond correctly to the updated values. You will connect through our secure remote tunnel, modify the logic, download it to the PLC, and stay online while we cycle the plant to confirm everything behaves as expected. After that, please add several on-screen quick buttons that trigger the valve-activation logic directly, giving operators a faster way to open or close individual lines without navigating deep menus. Deliverables • Updated sensor scaling to 0-100 • Revised control logic with full functional test • Custom quick buttons that activate the required valve logic • A brief hand-off note so we can maintain the changes going forward When you reply, highlight your experience performing similar Modbus or Schneider PLC updates and any remote commissioning you have handled; that will help me move quickly to award the work.
