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.
