  “ 
  Interoperable Functional Safety with OPC UA is Becoming a Reality与OPC-UA互操作的功能安全正在成为现实。
  ”
  The OPC UA Safety working group has achieved a key milestone publishing Release 1.00 of the specification for the interoperable communication standard for functional safety – OPC UA Safety “Part 15 OPC UA Core Specification”. OPC UA Safety is based on the black channel principle and currently addresses controller-to-controller communication using OPC UA clients/servers.
  近期,OPC UA安全工作组已经完成了安全通信标准的突破性推进,发布了可互操作的功能安全通信标准规范第1.00版——OPC UA安全“第15部分OPC UA核心规范”。OPC UA安全基于黑通道原理,当前使用OPC UA客户端/服务器的方式来实现控制器之间的通信。
  OPC UA has progressively expanded the applications that can be served by the technology. Safety is the next important part of the OPC UA specification family and is now achievable. OPC UA Safety takes the requirements of modern and future safety technology into account.
  OPC UA已经逐步扩大了该技术的应用范围。OPC UA规范系列的下一个重要部分着重于安全,目前来看是完全可以实现的。OPC UA安全规范因素融合考虑了现代和未来技术的要求。
  While addressing all safety requirements defined in the relevant international standards, OPC UA builds on experience from existing safety protocols and addresses new use cases that have emerged since their development. For instance, OPC UA Safety supports the assignment of Safety-IDs to series machines and allows for dynamically changing the communication partner during runtime: a prerequisite for modern production processes with batch size 1, where machines or machine parts must be re-grouped frequently. OPC UA Safety enables the transmission of up to 1,500 bytes of arbitrarily structured data in any network without limiting data rate for applications with a safety integrity level (SIL) of up to 4.
  OPC UA在处理相关国际标准中定义的所有安全要求的同时CONTROL ENGINEERING China版权所有,基于现有安全协议的经验,同时要衡量可能面临的新功能的应用。例如,OPC UA安全性支持将安全ID分配给一系列机器CONTROL ENGINEERING China版权所有,并允许在运行时动态实时更改通信对象:这是批量大小为1的现代生产过程的先决条件,在此过程中,机器或机器部件必须频繁地重新分组。OPC UA安全性允许在任何网络中传输最多1,500字节的任意结构化数据,而不限制安全完整性级别(SIL)最高为4的应用程序的数据速率。
  OPC UA Safety was initiated as a joint working group between the OPC Foundation and PROFIBUS & PROFINET International (PI) but has now been merged as a technical working group under the auspices of the Field Level Communication (FLC) initiative. Many well-known manufacturers are represented in the OPC UA Safety working group which ensures a uniformwww.cechina.cn, worldwide and coordinated standard for safe communication developed for the first time. OPC UA Safety now becomes a core part of OPC UA specification framework of the OPC Foundation. The next steps include defining of safety test specification for certification as well as extension to OPC UA Pub/Sub allowing real-time and isochronous real-time applications.
  OPC UA安全最初是OPC基金会和PROFIBUS & PROFINET国际(PI)之间的一个联合工作组,但现在已经在现场级通信(FLC)倡议的支持下合并为一个OPC UA安全技术工作组。许多著名的制造商代表是该小组的成员,为了确保全球范围内共同协调的统一标准安全通信问世。OPC UA安全目前已成为OPC基础的OPC UA规范框架的核心部分。接下来的工作步骤包括为认证定义安全测试规范,以及扩展到OPC UA发布/订阅模式,允许实时和同步的实时应用。
  Invitation to Participate
  邀请同仁参加
  The OPC Foundation invites all its members to participate in a co-funding project to develop a safety layer stack according to the OPC UA Safety specification (SafetyProvider and SafetyConsumer) which can be combined with different underlying communication stacks (client/server and pub/sub mapping).
  OPC基金会邀请其所有成员参与一个联合赞助项目,根据OPC UA安全规范(安全供应商和安全用户)开发一个安全层堆栈,可以与不同的底层通信堆栈(客户端/服务器和发布/订阅方式)相结合。
  A service provider will be contracted to perform the implementation and to prepare software, documentationCONTROL ENGINEERING China版权所有, verification and validation activities to allow a pre-certification of the software by notified bodies (e.g. TüV).
  该项目包括将与服务提供商签订合同,由其执行实施并准备软件、文档、验证和验证活动www.cechina.cn,以允许通知机构(例如TUV)对软件进行预认证。
  Each co-funding company will receive unrestricted IP and source code rights on the development. It is planned to put the developed software under a dual license: an open source license for the source code intended for evaluation purposes and a commercial license for the complete safety stack package (source code, verification and validation documentation) which is maintained and supported by one or several service providers.
  每个联合赞助企业将获得关于开发的不受限制的知识产权源代码权利。该计划将开发的软件双重许可协议:源代码的开源许可用于完整的安全评价目的和商业许可证栈包(源代码,验证和确认文档)的维护和支持的一个或多个服务提供者。
  The development costs will be shared equally between all participating companies.
  开发成本将由所有参与企业均摊。
