Device, System and Method for Connecting Field Bus Devices to the Internet

Simple SummaryContent extracted from patent full text and abstract with AI.

The patent discloses a gateway device, system, and method for connecting field bus devices (often found in automation, home, or industrial networks) to the Internet via IPv6 networks. Each device connected to a local field bus, which normally uses non-IP protocols, is assigned its own individual virtual IPv6 address, enabling direct identification and secure control from remote IP-based networks. The gateway also carries out protocol translation, manages security settings, and can adapt to different field bus types and configurations.

Use CasesContent extracted from patent full text and abstract with AI.

• Smart home automation, allowing direct internet-based control and monitoring of devices like thermostats, sensors, and actuators connected by field bus systems.
• Industrial automation, enabling remote diagnostics, management, and operations of field bus-connected machinery from web/cloud platforms.
• Building management systems that integrate legacy or field bus devices into modern IP-managed environments.
• Utility and energy management where field bus meters or controllers are made accessible to remote monitoring centers.
• Retrofit of existing field bus installations to enable IoT (Internet of Things) connectivity without replacing legacy devices.

BenefitsContent extracted from patent full text and abstract with AI.

• Provides unique and individual IP addresses to each field bus device, allowing granular control and monitoring.
• Enhances network security through filtering, access control, and device visibility management.
• Supports direct interoperability between legacy field bus devices and modern IP/Internet networks, extending device lifetimes and reducing upgrade costs.
• Allows scalable, flexible integration of multiple bus types and devices into one IP-based management platform.
• Simplifies device discovery, configuration, and access from remote sites, making it suitable for both small home networks and large industrial deployments.
