Hi there, I have read your requirements carefully, and I understand you need an experienced PLC programmer who can handle both the software and hardware side of the automation project, especially Modbus RTU/TCP communication, device integration, and troubleshooting. I'm a new freelancer, but I have rich experience in this field. I can support: -PLC programming and logic development -integration with sensors, actuators, and controllers -Modbus RTU / TCP configuration and debugging -communication fault tracing and stable data exchange -system testing and issue fixing I understand this kind of work needs practical problem-solving, not only code. My approach would be to first review the PLC platform, I/O layout, and Modbus architecture, then implement or refine the control logic, verify communication reliability, and test the full signal flow end to end. I am comfortable working with structured automation projects where wiring, device addressing, register mapping, and communication stability all matter. I also keep the work clean and documented so future maintenance is easier. Availability: Immediate Rate: As per your budget/project scope If I work with you, I feel happy.
