Siemens announces support for OPC UA with TSN networks
西門子宣布支持OPC UA TSN網絡

Siemens has announced that it welcomes the initiative previously published by the OPC Foundation to further enable OPC UA adoption throughout industrial automation by extending standardization and harmonization activities for OPC UA, including TSN-enabled Ethernet networks at the field level. Siemens, as a founding and board member of the OPC Foundation, is a supporter of the OPC UA technology and has been active in core standardization working groups for many years.

西門子宣布歡迎OPC基金會先前發布的倡議，通過擴展OPC UA的標準化和協調行動，進一步實現OPC UA在整個工業自動化領域的應用，包括現場級的TSN以太網網絡。西門子作為OPC基金會的創始成員和董事會成員，是OPC UA技術的支持者，多年來一直活躍于核心標準化工作組。

Siemens has experience and a history in the development and standardization of industrial communication systems. Siemens is actively participating in all relevant standardization bodies like IEEE, IEC, IETF, PI, OPC F, and many more not only as editor but also even as the convener and lead of the whole working group.

西門子在工業通信系統的開發和標準化方面擁有豐富的經驗和歷史。西門子積極參與IEEE、IEC、IETF、PI、OPC F等所有相關標準化機構，不僅是編撰者，還是整個工作組的召集人和領導者。

The latest example of Siemens leadership is the foundation of the international IEC/IEEE 60802 standardization group by Siemens. This group will standardize the so called “TSN Profile for Industrial Automation (TSN-IA Profile)” to ensure a multivendor converged TSN network approach for industrial automation where different applications and protocols like OPC UA, PROFINET, EtherNet/IP, etc. can share the same TSN network infrastructure. Additionally, an appropriate set of IEEE basic standards will be selected to run the different protocols on one and the same hardware base.

西門子領導力的最新實例是西門子創立國際IEC / IEEE 60802標準化小組。該小組將標準化一項“工業自動化TSN配置文件（TSN-IA配置文件）”，以確保工業自動化的不同供應商融合TSN網絡方法，其中例如OPC UA、PROFINET、以太網/IP等不同的應用和協議，可以共享相同的TSN網絡基礎設施。此外，將選擇一組合適的IEEE基本標準，在同一個硬件基礎上運行不同的協議。

Siemens shares the vision of the OPC Foundation to extend the scope of OPC UA down to field level communication and is looking forward to contributing in standardization activities in the upcoming working groups of the OPC Foundation concerning information models for devices, necessary adaption of OPC UA core standards, application profiles, etc.

西門子贊同OPC基金會的愿景，將OPC UA的范圍擴展到現場層面的通信，并期待著在OPC基金會即將成立的工作組中為標準化活動做出貢獻，這些工作組涉及設備的信息模型、OPC UA核心標準的必要調整、應用概況等。

Use cases which have not been well addressed in today’s industrial communication systems so far, like multi-vendor controller-to-controller communication or vertical communication from devices to upper systems via OPC UA, will be adopted first by the market. Therefore, joint working groups between PI and OPC F members were started several months ago. These working groups are addressing topics such as the standardization of Safety over OPC UA based on Profisafe mechanisms for controller-to-controller communication, and the mapping of Profinet into the OPC UA information model for multiple use cases, e.g. asset management and diagnostics. Customers can shortly benefit from these features without waiting for TSN by simply running the OPC UA protocols on existing PROFINET network installations. The PI organization contributes its technology expertise to the OPC Foundation, e.g. by opening the Profisafe mechanisms to be used via OPC UA and extending the respective rights to OPC Foundation members.

到目前為止，在當今工業通信系統中尚未很好解決的應用案例，諸如不同供應商控制器到控制器通信或者通過OPC UA從設備到上層系統的垂直通信，將首先被市場接納。因此，PI和OPC F成員之間的聯合工作組在幾個月前就已開始著手。這些工作組正在處理一些主題，例如基于Profisafe機制的OPC UA安全標準化，用于控制器與控制器之間的通信，以及將Profinet映射到OPC UA信息模型中，用于多種使用情況，例如資產管理和診斷等。客戶無需等待TSN，只要在現有安裝的PROFINET網絡上簡單運行OPC UA協議，就可以很快從這些功能中受益。PI組織向OPC基金會貢獻其技術專長，例如通過OPC UA開放Profisafe機制，并將各自的權益擴展到OPC基金會成員。

Field device level communications with cyclic IO communication, motion control and safety, will need an established ecosystem with stack providers, certification procedures, tools, and many more. Organizations like PI, ODVA, and others have put effort into completeness and quality of specifications, conformance testing, maintaining a vendor and user community.

具有循環IO通信、運動控制和安全性的現場設備級通信將需要一個具有堆棧提供商、認證程序、工具等既定生態系統。像PI、ODVA和其他組織已經在規范的完整性和質量、一致性測試、維護供應商和用戶社區方面付出了努力。

Siemens bears responsibility towards its installed base and therefore will continue in innovating Profinet to protect customers’ investments and to bring Profinet based on TSN to the next level. The converged TSN network and common hardware platforms for Profinet and OPC UA enable a smooth migration into the new TSN world. In addition, we ensure that with OPC UA including TSN, the fundamental principles in field device communication, engineering workflows, conformance testing, diagnostics, etc. will stay unchanged.

西門子對其客戶群負有責任，因此將繼續創新Profinet以保護客戶的投資，并將基于TSN的Profinet提升到新的水平。Profinet以及OPC UA通用硬件平臺和TSN網絡的融合，實現向新TSN領域的平穩遷移。此外，我們確保包括TSN在內的OPC UA、現場設備通信、工程工作流程、一致性測試、診斷等基本原則將保持不變。
