Siemens announces support for OPC UA with TSN networks
西门子宣布支持OPC UA TSN网络

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.

西门子宣布欢迎OPC基金会先前发布的倡议，通过扩展OPC UA的标准化和协调行动，进一步实现OPC UA在整个工业自动化领域的应用，包括现场级的TSN以太网网络。西门子作为OPC基金会的创始成员和董事会成员，是OPC UA技术的支持者，多年来一直活跃于核心标准化工作组。

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.

西门子在工业通信系统的开发和标准化方面拥有丰富的经验和历史。西门子积极参与IEEE、IEC、IETF、PI、OPC F等所有相关标准化机构，不仅是编撰者，还是整个工作组的召集人和领导者。

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.

西门子领导力的最新实例是西门子创立国际IEC / IEEE 60802标准化小组。该小组将标准化一项“工业自动化TSN配置文件（TSN-IA配置文件）”，以确保工业自动化的不同供应商融合TSN网络方法，其中例如OPC UA、PROFINET、以太网/IP等不同的应用和协议，可以共享相同的TSN网络基础设施。此外，将选择一组合适的IEEE基本标准，在同一个硬件基础上运行不同的协议。

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.

西门子赞同OPC基金会的愿景，将OPC UA的范围扩展到现场层面的通信，并期待着在OPC基金会即将成立的工作组中为标准化活动做出贡献，这些工作组涉及设备的信息模型、OPC UA核心标准的必要调整、应用概况等。

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.

到目前为止，在当今工业通信系统中尚未很好解决的应用案例，诸如不同供应商控制器到控制器通信或者通过OPC UA从设备到上层系统的垂直通信，将首先被市场接纳。因此，PI和OPC F成员之间的联合工作组在几个月前就已开始着手。这些工作组正在处理一些主题，例如基于Profisafe机制的OPC UA安全标准化，用于控制器与控制器之间的通信，以及将Profinet映射到OPC UA信息模型中，用于多种使用情况，例如资产管理和诊断等。客户无需等待TSN，只要在现有安装的PROFINET网络上简单运行OPC UA协议，就可以很快从这些功能中受益。PI组织向OPC基金会贡献其技术专长，例如通过OPC UA开放Profisafe机制，并将各自的权益扩展到OPC基金会成员。

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.

具有循环IO通信、运动控制和安全性的现场设备级通信将需要一个具有堆栈提供商、认证程序、工具等既定生态系统。像PI、ODVA和其他组织已经在规范的完整性和质量、一致性测试、维护供应商和用户社区方面付出了努力。

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.

西门子对其客户群负有责任，因此将继续创新Profinet以保护客户的投资，并将基于TSN的Profinet提升到新的水平。Profinet以及OPC UA通用硬件平台和TSN网络的融合，实现向新TSN领域的平稳迁移。此外，我们确保包括TSN在内的OPC UA、现场设备通信、工程工作流程、一致性测试、诊断等基本原则将保持不变。
