Neuron is an Industrial IoT (IIoT) connectivity server that bridges industrial devices and modern data platforms. It supports dozens of industrial protocols and converts them into MQTT for seamless integration between IIoT platforms and shop-floor devices.

Key features:

• Edge-native application with real-time capability and low latency at the edge.
• Loosely coupled modular architecture with pluggable modules for easy extension.
• Hot-pluggable plugins: update device and application modules at runtime.
• Broad protocol support: Modbus, OPC UA, Ethernet/IP, IEC 60870-5-104, BACnet, and more.
• High concurrency: connect many devices with heterogeneous protocols simultaneously.
• Built-in stream processing via eKuiper for rules and AI/ML analytics.
• Northbound access for MES/ERP, SCADA, historians, and analytics via Sparkplug B.
• Tiny footprint (<10 MB) and low CPU usage; runs on ARM, x86, and RISC-V.
• Flexible deployments: native binaries or containers.
• Manage devices and tags via HTTP API and MQTT API.
• Works well with EMQX, NanoMQ, and eKuiper.
• Core framework and Modbus/MQTT/eKuiper plugins are available under LGPLv3.

NeuronEX is the commercial distribution of Neuron, offering extended capabilities and professional support. Compared to the open-source Neuron:

• Extended protocol support: Additional industrial protocols (e.g., OPC UA, Siemens S7, Ethernet/IP, etc.)
• Advanced dashboard: Full-featured web UI with enhanced visualization and management capabilities
• Enterprise plugins: More southbound device adapters, northbound application connectors, and rule engines
• Cloud integration: Direct connectors for major cloud platforms (AWS, Azure, Google Cloud, etc.)
• Data security: Enhanced encryption, auditing, and compliance features
