工業用 イーサネット （Ethernet）
Scalable Ethernet, Timed to Perfection
工業用イーサネット（Ethernet）システムには、高度な確定性と信頼性が求められます。多くのファクトリー・オートメーション・アプリケーションでは、従来のシリアル式「フィールドバス」接続の代わりに イーサネット が使われるようになっています。これは イーサネット が高い帯域幅を持ち、企業ネットワークとリンクできるからです。ただ、イーサネット には本質的に、フィールドバス・システムのような確定的な応答性がありません。
この制約を解消するために、工業分野の主要 OEM は固有の イーサネット プロトコルを定義し、それがオープン標準として広く利用されるようになりました。PROFINET、Ethernet/IP、EtherCAT、ModbusTCP、その他いくつかのプロトコルがあります。一部のプロトコルは標準 TCP/IP イーサネット ネットワークと完全な互換性がありますが、その他のものは、確定的な応答を実現するためにデータ・リンク層、ネットワーク層、またはトランスポート層（OSI モデルの 2 ～ 4 層）に変更を加えます。これらのプロトコルは標準 イーサネット と共存できますが、各プロトコル間に確定的な応答による相互運用性はありません。
工業用 イーサネット への対応が求められる製品を設計する場合、さまざまな標準との互換性をもつリファレンス設計を選択することが重要です。さらに、TSN のような将来の機能拡張に対応するために、ソリューションを更新できるかどうかという点も考慮しなければなりません。
Deterministic Ethernet for Industry 4.0 Applications
See how this technology provides determinism at the node for factory devices so they do not have to worry about the effects of network traffic.
An Introduction on Implementing Industrial Ethernet
One obstacle that sometimes gets in the way of updating industrial protocols to Ethernet is an unclear implementation plan. This article looks at how an industrial plant might get started on the road from field bus to Ethernet.

Delivering Trusted Data in Key Application Areas
ADI Chronous solutions are designed and verified for robust operation in harsh industrial environments and offer effective security at each node point within a system. ADI’s understanding of network architectures coupled with its application knowledge of how data is collected, processed, and used throughout an operation all serve to inform the security and robust features present in the ADI Chronous offerings. These features make ADI Chronous an ideal choice for a number of markets.
Process and Factory Automation
Deterministic networks and gigabit performance is a requirement of the future factory or process automation system. ADI Chronous, delivers off-the-shelf, full featured solutions that reduce development effort, risk, and time to market for new standard adoption.
Connection Motion and Robotics
ADI’s Chronous enables synchronization across the boundary of the network into the application, from sub-1 μs right down to the PWM outputs within the servo motor control. This improves machining and production accuracy in multi-axis applications such as robotics and CNC machines.
Building Automation
Addressing the multiple bandwidth requirements of existing and future intelligent buildings, ADI Chronous provides reliable, secure, and trusted digital communications at all levels of the network.
Time Sensitive Networking (TSN) with ADI Chronous
ADI Chronous solutions are designed to address the requirements of time sensitive networking (TSN) and deterministic Ethernet. Time sensitive networking, or TSN, refers to a group of IEEE 802.1™ and IEEE 802.3™ standards developed to provide deterministic performance within standard Ethernet. It is a universal standard being developed at an industry level to eliminate interoperability problems between protocols. It allows current protocols to share networks and provide reliable deterministic communication and scalability across applications, bandwidths, and enterprises all the way to the edge node. Given that the TSN standard is nearly finalized, now is the time to practically deploy standard Ethernet (with the TSN extensions) in real-time, mission critical applications. New hardware and software will be required that can support all these TSN features and ADI Chronous is the ideal solution for scalable, robust solutions that are designed for ease of deployment.
The ADI Chronous portfolio is supported by a host of software elements that simplify the adoption and increase the reliability of each product offering. Supporting multiple protocols, ADI offers a choice of fully tested and verified, production ready software protocol stacks that accompany our hardware. From host software drivers to APIs and development tools, ADI has the software needed to make the adoption of new standards and technology quick and simple.
