KINDLY READ THROUGH MY PROPOSAL THIS IS WHAT I WILL DO - Deliver a compact, ready-to-flash DLMS-to-Modbus RTU gateway on STM32H743 (or ESP32-S3 if you prefer cheaper) – one RS-485 for meter, second for your MC-230-02 - Full DLMS client (using open-source Gurux stack, hardened) → extracts Voltage, Current, kWh total/interval, PF from your meter model - Clean Modbus server with exact register map (40001+) + scaling, updated every 2–5 s - Plug-and-play box: 24 V powered, DIN-rail case, config via USB/web (meter HDLC address, baud, OBIS list) RELEVANT PROJECTS - 2024: 120+ DLMS meters → Modbus gateways for Schneider PLCs, still running 18 months zero-fail - 2025: Same job for Landis+Gyr E450 to Modbus/TCP, 48 h logged proof attached to every unit QUESTIONS (so I ship the exact match first time) - Meter brand & exact model (or share the 10-15 most common OBIS codes you need)? - Preferred baud for DLMS side (9600 typical)? - Want the gateway powered from 24 V loop or separate supply? I already have 90 % of the code running on my bench. Give me your meter model and I’ll have a working, tested unit on your desk in 7 days max. Let’s make your PLC happy tomorrow! ?

Hi, how are you? I can deliver a fully engineered DLMS-to-Modbus gateway that your MC-230-02 PLC will read cleanly and reliably. My approach is not just a script—it is a hardened protocol bridge built for long-term field stability. I will implement a dedicated firmware layer that authenticates with the DLMS meter, extracts the required OBIS objects (voltage/current, cumulative & interval energy, and power factor), and exposes them as clean, deterministic Modbus Input/Holding registers. Every register will be clearly documented with a DLMS–to–Modbus mapping table designed specifically for your PLC’s polling style. You will receive: • Production-ready firmware or gateway software • Register-mapping documentation tailored to your meter and PLC • Configuration files + a concise setup guide • A 48-hour stability test log at 9 600–38 400 baud confirming accurate, uninterrupted readings The result is a plug-and-forget bridge: once installed, your PLC will see the metering data as if it came from a native Modbus device—stable, fast, and field-proven.

@Zack111Arya97

Hello — I’m Zakaria L, M.Sc. in Automatic & Systems Engineering. I will deliver a turnkey DLMS→Modbus-RTU gateway your MC-230-02 PLC can poll reliably. What I deliver • Working gateway (Raspberry Pi image or MCU firmware) exposing DLMS OBIS items as Modbus registers (Voltage, Phase Currents, PF, cumulative & interval energy). • Full OBIS → Modbus register CSV (address map, types, scaling). • Source code, systemd service / flash image, wiring diagram, and README. • Remote commissioning + configuration (baud/parity/IDs) and 48-hour stability run with test log & screenshots. • 30-min handover session. Process & timeline • 1–2 days: bench build + sample register map. • 1 remote session (1–2 hrs) for onsite wiring & validation. • Start 48-hour stability run immediately after. Total closure ≈ 4 days. Price: EUR 250 (fixed — includes 48-hr verification). I’ll handle OBIS differences and scaling during commissioning. I will need: meter model, DLMS auth (if used), and remote access or one RS-485 adapter on your side (I’ll advise exact hardware). If that works I’ll prepare a downloadable POC (one value) so you can test connectivity. Best regards, Zakaria L.

With extensive experience in embedded systems, electrical engineering, and protocol bridging, I’m confident in delivering a reliable gateway that accurately translates DLMS/COSEM metering data into Modbus RTU format. I will design a robust firmware layer or script with clean register mapping for voltage, current, energy consumption, and power factor. The output will seamlessly integrate with your PLC’s Modbus registers. Documentation will include mapping details, configuration files, and a setup guide. I’ll also provide a comprehensive test log demonstrating stable readings over 48 hours at requested baud rates. I suggest initiating with a system design and register mapping within 7 days, followed by firmware development and testing. I’m ready to start immediately and will maintain clear communication throughout. Could you share the preferred microcontroller platform or hardware environment for running the gateway firmware? Best regards,

@Sidrairfan078

Hi, I have carefully reviewed your project requirements for the DLMS-Modbus RTU Converter. I am confident in my ability to design an effective gateway that will translate the DLMS/COSEM protocol data into a format readable by your PLC MC-230-02. With my extensive experience in embedded systems and PLC automation, I can ensure reliable one-way data collection from your metering devices. The solution will include detailed register-mapping documentation for all key parameters—voltage, current, cumulative and interval energy consumption, and power factor—aligned with Modbus addressing. I will also provide configuration files or source code, a setup guide, and a test log demonstrating accurate polling over typical baud rates of 9600 to 38400. With a timeline of 7 days for completion, we can rigorously test the setup to confirm stable operation for at least 48 hours.

@TheDesignBloke

Hi Marjan, I understand the critical need for a reliable DLMS-Modbus RTU converter to ensure seamless data communication for your PLC MC-230-02. With a solid background in embedded systems and PLC integration, I can design a gateway that effectively translates DLMS protocols into Modbus registers, ensuring compatibility with your requirements for voltage, current, energy consumption, and power factor measurements. I will provide detailed register-mapping documentation, configuration files, and a comprehensive setup guide, along with a test log demonstrating stable readings over typical baud rates for a minimum of 48 hours. Let's discuss any specific preferences you might have for the project and finalize the details.

@ThynkLoop

We are Thynk Loop. I’ll build a reliable DLMS/COSEM → Modbus RTU gateway so your PLC MC-230-02 can poll voltage, current, energy and power factor as Modbus registers on RS-485. The solution will be a compact gateway (microcontroller or small SBC + RS-485 transceiver) that reads the meter’s OBIS objects and exposes mapped registers your PLC can poll. What you get: working gateway firmware or runnable software, a register map that shows each OBIS code and its Modbus address, configuration files, a short setup guide, and a 48-hour test log proving stable reads at your chosen baud rate. Implementation choices include an embedded MCU build for field reliability or a Raspberry Pi/industrial SBC for easier development; either uses a proven DLMS client library and a Modbus slave stack. I will implement safe polling schedules, retry/backoff on meter timeouts, simple scaling and units handling, and a small watchdog so the gateway stays online. To start I need your meter model and the OBIS codes you want read (or permission to autodiscover), PLC Modbus address ranges you prefer, RS-485 wiring and baud/parity settings, and access method to the meter (optical port, RS-485, TCP). Once I have that I’ll provide a short plan and a firm delivery estimate.
