The complete software for Smart Grid data concentrators
Easily create, customize, and deploy resilient DCU solutions—on dedicated hardware or a split cloud-edge architecture. Battle-tested across 60 000 substations gathering data from 3M+ meters via PRIME PLC.
Features
Field-Proven Deployment
Runs inside 3 commercial Phoenix-RTOS-based DCU platforms and successfully ported to 2 third-party commercial devices, entirely replacing their legacy software stacks.
Flexible Architecture
Supports standalone operation on dedicated DCU hardware, or a split configuration partitioned between cloud orchestration and edge-level smart meters to target islanded locations.
Certified, Software-Defined PLC Stack
Software-implemented communication stacks with native multi-channel support for both PRIME and G3-PLC protocols in CENELEC A and FCC bands.
Broad Hardware Interoperability
Integration with industry-standard Analog Front-Ends, including TI AFE031, TI AFE032, NJM45001, and ATPL220A.
Certification Toolkit
Built-in protocol primitives and compliance layers designed to streamline and accelerate official hardware qualification.
Multiple DLMS/COSEM models support
Highly modular architecture featuring simultaneous multi-model profile management for seamless multi-vendor meter environments.
Scalable HES interface
DCU can be scaled to support many HES protocols. Natively supports DCSAP.
Balancing meter
Balancing meter functionality to measure energy parameters directly on the substations.
Multiples OS support
DCU functionality can be run under Phoenix-RTOS or GNU/Linux supervision.

Inside the Platform
DCU Application
Parallels collect data from up to 2,048 smart meters simultaneously, maintaining strict 15-minute granularity.
Software-Defined PLC Stack
Complete software-executed both Physical (PHY) and Media Access Control (MAC) layers driven by Phoenix-RTOS deterministic real-time scheduling.
Metrology
Balancing meter module with comprehensive DLMS/COSEM registers set, running entirely within an isolated user-space process for system stability.
Advanced GUI
A web interface providing deep grid visibility—combining high-level substation data aggregation with granular, per-meter connection state.
Certification Toolkit
Substation-level digital signal processing with an integrated PLC spectrum analyzer for real-time noise and interference detection and pinpoint.
Security Suite
Edge protection featuring native 802.1x, IPSec, TLS, OpenVPN, Wi-Fi WPA2, and automated device certificate lifecycle management.
Architecture
Phoenix-DCU features a highly modular, decoupled architecture where critical system components run as isolated user-space applications under POSIX compliance.
Key Architectural Highlights
- Modularity: software is implemented as a set of components communicating using message passing
- Software-defined architecture: key components implemented as software modules running under Phoenix-RTOS operating system.
- Resource efficiency: Fully operational on cost-effective hardware, requiring just 128 MB RAM.
- Hardware abstraction: Optimized for ARMv7 Cortex-A7 and compatible silicon architectures.
Licensing & Source Access
Phoenix-DCU is provided as a production-grade set of software packages tailored for seamless deployment under either the Phoenix-RTOS microkernel or monolithic GNU/Linux. The framework is delivered under a straightforward commercial model based on three core components.

Source Code License
Provides your engineering team with 100% visibility and full access to the core framework codebase, software packages, and SDK tools enabling to freely develop, customize, port to new hardware, and perform independent zero-trust security or compliance audits.

Per-Device License
A scalable, volume-based production fee applied to each active unit deployed in the field. This covers both dedicated standalone hardware DCUs and individual smart meters transformed into active data concentrators.

Support Fee
An ongoing maintenance and technical support fee that guarantees your project continuous access to software updates, security patches, protocol revisions, and direct engineering backing from our core architecture team.
