Context
Industrial systems operate under constraints that traditional software is not designed for: intermittent or unreliable connectivity, heterogeneous hardware and protocols, continuous operation requirements, and zero tolerance for data loss. The goal was to create a system that could reliably bridge physical devices and cloud infrastructure..
Industrial facility with connected systems
Problem
The challenge was not just data collection — it was guaranteed data integrity and system reliability at the edge. This required solving: - Handling multiple industrial protocols consistently - Ensuring no data loss during network outages - Enabling autonomous edge operation - Supporting safe remote updates - Maintaining predictable system behavior.
Intervention
Relayforge designed the system as a pipeline-driven edge runtime. **Protocol Abstraction Layer** Unified support for Modbus (TCP/RTU), BACnet, and PLC integrations.
This avoids fragmented integrations and standardizes data ingestion. **Edge Processing Pipeline** Collector → Processor → Uploader.
Each stage handles ingestion, normalization, batching, and transmission.
This ensures consistent and controlled data flow. **Offline-First Design** To handle unstable networks: local buffering, retry queues, exponential backoff, and disk and memory safeguards.
The system continues operating independently of connectivity. **OTA Update System** A full update lifecycle including signed update bundles, atomic deployments, and automatic rollback.
This enables safe fleet-wide updates..
A production-ready edge computing layer deployed across multiple industrial facilities
99.9% uptime with guaranteed data integrity and zero network-dependent failures
Architecture
Industrial Devices → Edge Runtime → Local Pipeline → Buffered Storage → Cloud Processing Key Design Decisions: - Offline-first system design - Pipeline-based processing model - Protocol abstraction over direct integration - Safe OTA deployment strategy - Local-first reliability guarantees.
Outcome
The system functions as a reliable edge computing layer that: - Prevents data loss through buffered storage - Supports multiple industrial systems via protocol abstraction - Scales across deployments with consistent architecture - Enables real-time monitoring through structured logging This project highlights Relayforge's expertise in edge computing, industrial systems, real-time data pipelines, and hardware-software integration..
