Renesas MCU IEC104 TCP/IP Firmware using quectel

@AlexandrGergel

Greetings, I worked on cellular IoT firmware where the device communicated with external equipment over UART and kept a stable 4G connection for sending data to remote servers. I also have experience with RS232/RS485, custom protocols, TCP sockets, and handling reconnect/network recovery on embedded systems. For your project, the key part is making the EC200 connection reliable while polling up to 100 PLC tags every 4 seconds and sending data to three destinations without blocking PLC communication. I would build it with separate communication/state handling for PLC, TCP and IEC 104, and I expect a first demo with one PLC protocol and network upload in around 3–5 days; the complete 10-PLC support depends mainly on the protocol documents and test access. One question: for the 10 PLC types, will you provide the register/protocol specification and sample communication data for each one? Sincerely, Oleksandr

@markoa7

I will develop robust firmware for the Renesas MCU to collect data from PLCs via RS-232/RS-485 and push it to the cloud in IEC104 and Modbus formats over TCP/IP. The code will be in C++ Programming and designed with Data Collection in mind. Plan to support up to 10 PLC types, 100 tags, with 15 carried forward in 104 format, and data dispatched every 4 seconds to three IP addresses. The EC200 module will maintain the network connection and handle fault tolerance. Deliverables include source, build instructions, test scripts, and a concise integration guide. I will verify timing, latency, and data integrity across all channels. We can tailor the toolchain to your cloud and protocol preferences. What is your preferred cloud endpoint and security protocol for the 4-second updates, and should the 15 selected tags be mapped to IEC104 or Modbus TCP formats? Marko Aleksic

Hi, how are you doing? I have carefully studied your project description and understand that you need a reliable PLC data acquisition and cloud communication solution using the EC200 module. Your requirements perfectly match our expertise, and I am very confident that we can develop the required system with stable and continuous network connectivity. We are a team of expert Electrical, Electronics, Embedded Systems and IoT Engineers with extensive experience in PLC communication, industrial protocols, embedded programming, cellular modules, and cloud data integration. We will develop the communication logic to collect up to 100 tags from 10 different PLC types through RS232/RS485 interfaces, supporting Modbus and proprietary PLC protocols according to the formats you provide. The controller will process the collected data and transmit it every 4 seconds to the specified IP destinations simultaneously, including TCP/IP communication and the two required 104-format locations, with the selected 15 tags mapped accordingly. A major focus will be maintaining a persistent EC200 network connection, including connection monitoring, automatic reconnection and reliable data transmission after network interruptions. The software will also be structured to handle different PLC configurations and data formats cleanly for future expansion and troubleshooting. Budget: $800–$1,200 | Ideal Deadline: 10–14 days

I’ll structure the firmware around a single normalized tag table that absorbs all ten PLC protocol variants, so RS232/RS485 polling and parsing stay modular and easy to extend when you supply the exact frame formats. The Quectel EC200 will run as a persistent managed link with auto-reconnect and periodic keepalive, ensuring the connection never silently drops. Every 4 seconds the 100-tag dataset is packed into the TCP/IP stream, while the designated 15 tags are converted into IEC104 and pushed to the two 104 destinations simultaneously. The tag-to-register mapping and protocol definitions will be isolated in configuration so your PLC-specific structures can be added without touching the core communication loop.

@alfatrade2

With 100 tags refreshing every 4 seconds across three IP destinations plus a parallel IEC104 feed for 15 of them, the real risk sits in the EC200 link — a dropped cellular session mid-cycle needs a reconnect and re-sync path that doesn't stall the next push. I've written microcontroller firmware handling sensor input and drive control in C/C++ on similar embedded targets. Are the 10 PLC protocols documented per-device, or will some need reverse-engineering from captured traffic on-site?

@bojans9

Hello — I can develop firmware for your R7FS5D37A3A01CFP that polls up to 10 PLCs over RS232/RS485 (Modbus + custom frames) and pushes up to 100 tags every 4 seconds to three IP endpoints: one raw TCP and two IEC‑104, with only 15 selected tags mapped into 104. My approach: 1. PLC layer: UART drivers + per‑PLC protocol handlers based on your formats. 2. Tag engine: configurable mapping of PLC registers to internal tag table. 3. Comms: IEC‑104 client + TCP client, sending in parallel to all three IPs. 4. Quectel EC200: robust network management (APN, reconnect, watchdog, link monitoring) so the module stays online. I’ll structure the code in C with clear modules and add test hooks so you can simulate PLC data and verify cloud payloads before field deployment. If you share hardware pinout, PLC specs and cloud message formats, I can outline the exact architecture and milestones.

Hi We are available. We recently built a similar IoT data ingestion edge system for an industrial client that needed reliable data collection from multiple PLC brands and protocols. We used C/Python on embedded modules to poll registers over RS232/RS485 using Modbus RTU and proprietary drivers, buffering the payload locally to ensure zero data loss during network blips. We implemented multi-socket concurrent pushing over TCP and IEC 60870-5-104 protocol stacks to transmit 100+ tags across 3 distinct IP endpoints at exact 4-second intervals. We optimized the cellular modem connection loop on Quectel EC200 modules to maintain persistent socket connectivity with automatic keep-alive and background reconnect logic. Our suggestion would be to build this with an embedded edge firmware layer deployed on your hardware, connected to a scalable cloud backend. We’d use embedded C/C++ or Python for the EC200 module edge service handling Modbus/RS485 polling, memory buffering, and simultaneous TCP/104 transmission, paired with Node.js and PostgreSQL/TimescaleDB on the server side for receiving and indexing the streams. AI protocol detection and remote device management services would be implemented as separate modules so new PLC types can be added without disrupting live telemetry. We are eager to discuss the project further. Reach out to initiate a conversation! Best regards, Quantum Code Solutions
