Renesas MCU IEC104 TCP/IP Firmware using quectels

@toriquldev123

Hello Dear, I’m Md Toriqul Islam, and I’m excited to partner with you & I can dive into your project immediately. I understand you need to collect up to 100 PLC tags through RS232/RS485, supporting Modbus and custom PLC protocols, then transmit selected data every 4 seconds to multiple cloud IP destinations simultaneously. I have rich experience in Python, C/C++, TCP/IP, Modbus, RS232/RS485 communication, IoT data collection, and cloud integrations. I am skilled in building reliable communication systems with automatic reconnect, buffering, error handling, and continuous EC200 network connectivity. I can develop the system for all 10 PLC types according to your provided formats and ensure stable 24/7 operation. Best Regards, Md Toriqul Islam

Having spent extensive years in industrial automation, particularly in areas of wastewater treatment and water treatment plant automation, I bring a comprehensive understanding of PLCs, protocols like Modbus, and the nuances of pushing data into cloud servers for efficient monitoring. As part of my work, I've proficiently implemented TCP/IP format across various systems thereby making Renesas MCU IEC104 TCP/IP Firmware with Quectels quite familiar to me. My proficiency in C++ Programming does not just limit itself to writing code but extends to undertaking and successfully executing complex projects such as yours. Connecting an ec200 module consistently to network without any disruptions for ensuring real-time data transfer is an area where I excel. Further, with the ability to work under pressure while maintaining rigor for delivering impeccable work on-time sets me apart. Throughout my career, I have dealt with diverse models of PLCs and their various formats thus your 10 type PLCs will be in capable hands. With an eye for detail that abides by 4-second intervals thoroughly alongside experience in pulling out the required16 tags efficiently from 100 tags emphasizes my diligent approach for industrial automation projects.I also understand that successful project execution goes beyond just writing code which is why my expertise on SIEMENS WinCC SCADA program for monitoring & reporting plays a pivotal role. Let's connect and discuss further

I deliver 100% work — 99.9% is not for me. Workflow Diagram PLC Protocol Review ⟶⟶ RS232/RS485 Communication ⟶⟶ Modbus/Custom PLC Drivers ⟶⟶ Tag Collection ⟶⟶ EC200 Network Manager ⟶⟶ 4-Second Data Push ⟶⟶ TCP/IP + IEC-104 Output ⟶⟶ Multi-Server Delivery ⟶⟶ Testing Key Highlights • Develop embedded communication software for up to 10 PLC types using RS232/RS485 interfaces. • Support Modbus RTU/TCP and PLC-specific protocols based on the formats and structures you provide. • Read up to 100 PLC tags and push collected data every 4 seconds to three IP destinations simultaneously. • Implement standard TCP/IP data transmission for the complete required tag set. • Map and transmit the selected 15 tags using IEC 60870-5-104 format. • Build robust EC200 cellular-network logic with automatic reconnect, connection monitoring, retry/backoff, watchdog handling, and recovery after signal/network loss. • Keep PLC drivers modular so additional PLC models or protocol formats can be added later without changing the complete application. • Add buffering/error handling to prevent temporary network drops from breaking the acquisition cycle. • Test serial communication, tag parsing, 4-second timing, simultaneous server transmission, and long-running EC200 network stability.

Three IPs every 4 seconds with only 15 of 100 tags going out as IEC104 ASDUs, all off a single R7FS5D37A3A01CFP — that's a buffer-separation problem more than a parsing one. I've handled data exchange between shop-floor tooling and a PC on a profile-cutting automation line with feedback positioning, so juggling protocols over serial against one network stack isn't unfamiliar. Is SIM/APN provisioning on the EC200 already done, and are all 10 PLC types Modbus, or is one proprietary?

YOU ONLY NEED ONE DEVELOPER WHO GETS IT RIGHT THE FIRST TIME. HERE'S WHY I'M THAT DEVELOPER. I recently helped a client transform their idea into a modern, high-quality digital solution that was both reliable and easy to scale. I'd love to do the same for you and deliver something that's built to perform from day one. I understand you need to collect data from multiple PLCs and push it to a cloud server seamlessly and reliably. Your focus on TCP/IP format and IEC104 protocol is crucial for efficient data transmission. I specialize in embedded firmware development, and we have 75+ 5-star reviews on similar projects and rank in the top 1% among 75 million users. I'd love to chat about your project! The worst that can happen is you walk away with a free consultation. Regards, Aydon.

Hello, your hardware setup and data flow are clear, and this is exactly the kind of embedded work I handle. I can build firmware on the R7FS5D37A3A01CFP that reads each PLC over RS232/RS485, parses Modbus or your custom frames, and pushes up to 100 tags every 4 seconds. I’ll structure two parallel outputs: one TCP stream for all tags and one IEC104 stream for the selected 15, with proper ASDU handling. The EC200 will run with a stable connection loop, watchdog, and auto‑recovery so it stays online. Before coding, I’ll review your protocol formats and test against your hardware. Your budget is tight for full IEC104 + multi‑PLC support, but we can start with a working core pipeline and extend from there. If you want, share the frame docs and I’ll outline the first milestone.

@LeonBoshoff

The goal of your project to collect data from multiple PLCs and push it to cloud servers aligns perfectly with my recent work in developing firmware for similar applications. I have experience with TCP/IP communication and have successfully implemented data collection systems using various protocols like Modbus. I noticed you require the firmware to push data every 4 seconds to three different IP addresses. This kind of real-time data transfer is crucial, and I understand the importance of reliability and network connectivity, especially with the EC200 module. With a strong business understanding and a focus on clear communication, I ensure that development supports your specific objectives. My practical approach to firmware design means I prioritize efficient, scalable solutions. What is your preferred method for testing the firmware with the PLCs? Regards, Leon B.
