Hartley Net represents a cloud based connectivity layer designed to bring industrial protocols and edge devices onto modern IP networks. This platform focuses on secure data routing, protocol translation, and simplified device management for distributed infrastructures.
Organizations adopt Hartley Net to bridge legacy equipment with cloud analytics while enforcing access controls and encryption. The approach emphasizes operational continuity and visibility across heterogeneous environments.
| Aspect | Description | Impact | Typical Use Case |
|---|---|---|---|
| Core Function | Acts as a secure bridge between field devices and cloud applications. | Reduces integration complexity and network exposure. | Connecting PLCs, RTUs, and sensors to cloud platforms. |
| Protocol Support | Covers Modbus, DNP3, MQTT, BACnet, and vendor specific protocols. | Enables interoperability across legacy and modern devices. | Integrating plants with mixed automation generations. |
| Security Model | Leverages mutual TLS, device authentication, and policy based access. | Limits unauthorized access and lateral movement. | Meeting industrial cybersecurity standards and compliance. |
| Deployment Mode | On premises gateway with cloud managed orchestration. | Balances low latency edge processing with centralized oversight. | Distributed sites with centralized SCOT and monitoring. |
Architecture and Deployment Patterns
Edge Gateway Design
The Hartley Net gateway runs a hardened runtime that terminates encrypted tunnels and enforces data policies locally. Resource constrained sites benefit from low bandwidth usage and intermittent connectivity support.
Cloud Control Plane
From the cloud console, administrators define routing rules, monitor device health, and rotate credentials at scale. Role based access and audit trails align with enterprise governance requirements.
Security and Compliance Features
Transport Protection
Mutual TLS ensures only authenticated devices join the mesh, while payload encryption in transit protects sensitive process data from interception.
Policy Enforcement Points
Fine grained policies limit which source and destination addresses each gateway can forward, effectively segmenting process networks from IT and cloud services.
Operational Monitoring and Diagnostics
Built in telemetry exposes link quality, throughput, and error metrics that feed into existing observability stacks. Historical trends help teams correlate network events with process anomalies.
Integration with Automation Ecosystems
Hartley Net includes adapters for historian databases, SCADA servers, and IIoT platforms to streamline dataflow without custom scripting. Standard APIs and webhooks enable rapid orchestration with external applications.
Key Takeaways and Recommendations
- Review protocol coverage against your existing device inventory before deployment.
- Plan gateway placement to balance edge compute resources and network topology.
- Define role based access and least privilege policies early in implementation.
- Leverage built in monitoring to set alerts for latency, packet loss, and device status.
- Test failover and recovery procedures regularly to ensure business continuity.
FAQ
Reader questions
How does Hartley Net handle legacy devices with proprietary protocols?
It uses protocol adapters and translation modules that map proprietary frames to standardized payloads, allowing older equipment to interoperate without hardware replacement.
Can Hartley Net operate in air gapped environments with no internet access?
Yes, gateways can run in fully offline mode, synchronizing policies and firmware updates via removable media while still providing local device integration.
What performance limits should I expect under high data sampling rates?
Throughput and latency depend on gateway CPU, link bandwidth, and concurrency; sizing tools and benchmarks help match hardware profiles to your tag count and frequency.
How are firmware updates and security patches delivered to deployed gateways?
Updates are staged through the cloud control plane, validated via checksums, and applied in rolling batches to minimize disruption and ensure integrity.
