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。

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.

ADI Chronous Software Suite for Fast Development and Seamless Operation

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.
