@electronicdog

Hi, I'm a lead engineer working on automotive ECU firmware: UDS diagnostics, flash bootloaders, and I build production STM32 firmware in C on FreeRTOS. Latest delivery: a field controller with a full Modbus map, fault handling and signed field updates. I'm new to IEC 61850, so I'll prove it before you pay for it. Stack (licensing up front): • STM32H7 + FreeRTOS + lwIP, GCC/CMake • Modbus RTU/TCP: my own stack • DNP3: opendnp3 (Apache-2.0) • IEC 61850: libIEC61850 (GPLv3 or commercial license) • Secure boot: MCUboot (Apache-2.0), signed A/B images, rollback This bid is Phase 1 (45 days): Modbus, DNP3, secure boot, metering/protection framework. Milestones: Modbus on board 20%, DNP3 30%, secure boot + metering/protection 30%, tests + docs 20%. Includes source + build scripts, pre-conformance reports, manual (registers, memory map, update procedure) and 30 days of FAT support. Formal lab certification is separate. Phase 2 (IEC 61850 model + GOOSE) will be quoted after I show you a working 61850 demo; estimate ₹300–400k, 6–8 weeks. What is your target MCU/board and which protection functions do you need?

@rakhshanz3

With my extensive background and technical expertise in firmware development, along with a deep understanding of embedded C/C++ programming and the protocols you've specified (Modbus, DNP3, IEC 61850), I am confident that I am an excellent fit for your RTU project. Moreover, I have a track record of successful development projects in utility-grade systems which gives me a unique perspective on the challenges and requirements specific to this industry.

@melopgabriel

Hello, Primary implementation risk is meeting IEC 61850 timing and memory constraints while also providing secure boot, comprehensive fault handling, and native Modbus and DNP3 without external gateways. GOOSE and SV timing, deterministic resource use on constrained flash/RAM, and certificate/provisioning for secure boot are the items I address first. I have delivered multiple utility-grade firmware projects in embedded C/C++ for ARM Cortex-M and Cortex-A platforms where I implemented Modbus TCP/RTU, DNP3 (OpenDNP3), and IEC 61850 stacks, plus meter and protection logic. Those engagements included protocol conformance testing and producing factory acceptance artifacts and user manuals. I can discuss specific code excerpts and test reports on request. I will start by producing a compact architecture: hardware abstraction layer, protocol task separation, memory pools for IEC 61850 datasets, and secure boot integration. My preferred toolchain is arm-none-eabi GCC with CMake/Make build scripts, using FreeRTOS or a minimal RTOS where deterministic threading is required; for higher-end SOCs I use Yocto-based Linux builds. Third-party stacks I typically integrate are libIEC61850 (C), OpenDNP3 (C++), and FreeModbus, with commercial stack substitution if you require vendor certification. I will supply build scripts, CI cross-compile recipes, and conformance test reports for Modbus, DNP3, and IEC 61850. - Do you have a target CPU/MCU, flash/RAM budget, and preferred secure element for secure boot? - Would you prefer an RTOS-based deliverable or a bare-metal image for initial bench testing? Sincerely, @melopgabriel

@hexabitzprojects

Hi, I can develop the **production-ready RTU firmware** covering protection/control, monitoring/metering and communications. I have **16 years of embedded R&D experience** with STM32/MCUs, industrial automation, RS485/Modbus, real-time firmware, data acquisition and communication gateways. I have worked on industrial IoT systems involving PLC communication, multiple data points and protocol-based integration. I can build a modular **Embedded C/C++ architecture**, with RTOS where appropriate, separating protection/control, metering, communications, diagnostics and firmware update functions. The communication layer can integrate **Modbus, DNP3 and IEC 61850** using suitable stacks after confirming the MCU resources and licensing requirements. I will be transparent that I cannot claim a previous utility-grade IEC 61850 deployment without evidence, but I can evaluate and integrate the required stack against your hardware and conformance requirements. Deliverables will include **compilable source/build scripts, protocol test documentation, configuration registers/memory map, firmware-update procedure and bench/FAT support**. I can first review the target MCU, hardware, I/O, protocol profiles and memory constraints, then propose the development environment, RTOS architecture and third-party stacks before implementation.

@ThynkLoop

Hi, I can develop the RTU firmware with protection/control logic, monitoring and metering, and native Modbus, DNP3, and IEC 61850 communication. Proposed Approach: Set up the embedded C/C++ firmware environment. Implement protection, control, monitoring and metering functions. Integrate Modbus, DNP3 and IEC 61850 protocol stacks. Add secure boot, fault handling and memory optimization. Perform protocol and bench testing. Provide documentation, build files and factory testing support. Deliverables: Production-ready RTU firmware Modbus, DNP3 and IEC 61850 integration Protocol test reports Build scripts and source code Configuration/memory documentation Firmware update procedure Factory acceptance testing support

@OptimumGrpCorp

Hi, I hope you're doing well. I understand this is a production-grade RTU firmware project where protection/control, monitoring/metering, and native Modbus, DNP3, and IEC 61850 communications must operate reliably on constrained embedded hardware. Secure boot, deterministic fault handling, memory efficiency, and factory acceptance testing are equally important. I will develop the firmware in embedded C/C++ with an appropriate RTOS where the MCU and timing requirements justify it. I’ll structure the protocol layers independently, integrate the required IEC 61850 services/data models alongside Modbus and DNP3, and keep protection/control logic isolated from communications for predictable behavior. I’ll also implement secure boot/update handling, watchdog and fault recovery, diagnostics, memory/resource monitoring, and hardware abstraction to simplify testing. Build scripts, configuration/memory documentation, protocol test evidence, and bench-test support will be included. I’ll establish the MCU/toolchain and third-party stack choices against the target hardware and licensing requirements before implementation, then validate the firmware progressively through integration and factory acceptance testing. Best regards, Mikhail

@batuhanakkova

Dear Client, As an Aerospace & Embedded Systems Engineer specializing in hard real-time control, industrial networking, and deterministic architectures (C/C++ & FreeRTOS/Zephyr), I am well prepared to engineer your production-grade Remote Terminal Unit (RTU) firmware. Protocol Stacks & Tooling: IEC 61850: Integrating libIEC61850 (GPL/commercial license) on embedded Linux or RTOS (FreeRTOS/Zephyr) to handle MMS client/server, SCL/CID file parsing, and zero-jitter GOOSE publisher/subscriber tasks directly over Ethernet MAC layer. DNP3 & Modbus: Leveraging opendnp3 (Apache 2.0) for DNP3 outstation (TCP/Serial) with secure authentication (SAv5), and FreeModbus for RTU/TCP server maps. Dev Environment: GCC/Clang cross-toolchain with CMake, Ninja, and containerized Docker builds for reproducible compilation. Protection, Metering & Security: Zero-heap runtime loops for high-rate analog RMS/metering calculations and protection logic trips (<10 ms response), paired with hardware root-of-trust (crypto element/TPM) for secure boot and signed updates (MCUboot/X.509). Deliverables Fully documented C/C++ source code, CMake scripts, and memory maps. Automated protocol conformance test logs and bench validation reports. Complete user manual and direct bench support through FAT sign-off. Ready to review your MCU target and hardware schematics to begin immediately! Best regards, Batuhan Akkova

@CharlSche

We recently completed a similar firmware project focused on IEC 61850, ensuring seamless integration into substation networks. Your requirements for protection and control logic, along with full monitoring and metering capabilities, align perfectly with our expertise. With extensive experience in embedded C/C++ development, I can guarantee secure boot, robust fault handling, and efficient memory utilization. I’m also open to discussing alternative languages or RTOS approaches if they offer comparable reliability. Could you share more about your current development environment? Additionally, do you have a preference for any specific third-party stacks that might impact licensing? I would like to discuss your project in further detail. Best Regards, Charl

@ElectronicsMust

Dear Client, For an RTU, the expensive failures usually appear at the boundaries: protection logic behaving differently under fault conditions, protocol objects becoming inconsistent across Modbus/DNP3/IEC 61850, or firmware updates compromising field reliability. I have 11+ years of embedded/electronics experience across 500+ assignments involving MCU systems, industrial communication, protection/control interfaces, firmware integration, debugging, hardware validation and production support. My approach: RTU Architecture → I/O & Protection Model → Data/Object Mapping → Modbus/DNP3/IEC 61850 Integration → Secure Boot → Fault Handling → FAT/Conformance Testing I would focus on deterministic control execution, protocol-to-data-model consistency, watchdog/recovery strategy, configuration integrity, memory discipline, secure firmware update and testability from the start. I can support embedded architecture, protocol-stack integration planning, register/object mapping, hardware/firmware interfaces, validation strategy, bench/FAT support and production documentation. I would not claim previous utility-grade IEC 61850 firmware or conformance certification unless I can document it. Two important questions: 1. Which MCU/SoC and RTOS are selected for the RTU? 2. Do you already have licensed DNP3/IEC 61850 stacks, or should stack selection/licensing be part of the scope? Profile: https://www.freelancer.in/u/ElectronicsMust Kind Regards, Avi Gupta Quality is never an accident

@samnangy4

Hi, This RTU requires a reliability-first firmware architecture because protection/control, metering, and three industrial protocols must operate predictably under real-time and fault conditions. I can structure the firmware around embedded C/C++ with an RTOS where appropriate, separating: • Protection and control logic • Monitoring, alarms, event handling and metering • Modbus, DNP3 and IEC 61850 communication services • Secure boot and signed firmware updates • Watchdog, fault recovery and diagnostic logging • Deterministic task scheduling and memory management • Hardware abstraction for easier board/MCU adaptation For protocol implementation, I would evaluate proven third-party stacks rather than building IEC 61850/DNP3 from scratch, with licensing reviewed before integration. The build will include configuration/register mapping, protocol test procedures, update documentation and support through bench/FAT testing. I won’t claim a previous utility-grade IEC 61850 production project that I cannot verify. Before finalizing the development environment and protocol stacks, I’d need the MCU/SoC, available RAM/flash, Ethernet/serial interfaces, I/O architecture, metering requirements and RTOS preference. Please share the RTU hardware specification/schematic and protection requirements so I can map the firmware architecture correctly.
