Hello, I am highly interested in your project. I can develop the Router C application to convert master Modbus RTU requests into Modbus TCP, ensuring reliable communication and proper protocol handling. I plan to implement a mapping layer for RTU-to-TCP translation, handle exception responses, and include any additional processes you require. Could you clarify the number of devices and registers involved, expected polling rates, and any specific timing or latency constraints? Are there additional processing steps beyond standard Modbus conversion that should be integrated? I look forward to hearing from you. Thank you.

Hi there, you need a bridge that listens to a Modbus RTU master on serial and forwards those requests as Modbus TCP with proper MBAP/Unit-ID mapping, plus any extra processing (e.g., filtering or register remapping). I recently delivered a Raspberry Pi–based RTU↔TCP gateway with libmodbus that sustained ~1,200 req/min, with logging and solid timeout/retry logic. I’m hands-on with RTU framing (3.5‑char gap), MBAP/transaction IDs, RS‑485, and can package this as a service or Docker image. If you share the exact “additional processes” you need, I can send a quick plan and a small POC outline today. Best regards

Hello! I'm excited to see your project — it aligns with my experience. I have worked on multiple industrial automation and communication projects involving Modbus RTU and Modbus TCP, including protocol conversion, device integration, and data handling for SCADA/PLC systems. For your requirement, I can develop a robust gateway application in C, C++, or C# that listens to Modbus RTU master requests over a serial interface, converts them into Modbus TCP frames, and routes them to the correct TCP server, ensuring accurate function code and CRC/MBAP header handling. Additional processes such as data logging, filtering, mapping, or real-time analytics can be integrated into the conversion workflow without affecting latency. I have experience with multi-threaded architecture to handle multiple concurrent requests, as well as implementing error handling, retry logic, and performance optimization for industrial environments. The solution can run on Windows or Linux, and I can package it as a standalone service or lightweight executable for easy deployment. Q1: Which hardware/OS environment will the converter run on (e.g., Windows PC, embedded Linux box)? Q2: Should the additional processes run in real time during conversion or be handled asynchronously in a separate module? Hope we can team up and make this project a success! Thank you for considering my proposal. Adison.
