OPC Foundation, PLCopen and OMAC start OPC UA communications collaboration
OPC基金会，PLCopen和OMAC启动OPC UA通信协作

The Organization for Machine Automation and Control (OMAC), OPC Foundation, and PLCopen are working together to help further advance the communications protocols necessary for the Industrial Internet of Things (IIoT). The three organizations are developing and promoting common standards to help improve manufacturing efficiency, but until now have been working in parallel on different aspects of automation standardization.

机械自动化与控制组织（OMAC），OPC基金会，和PLCopen正在共同努力，以帮助进一步推进工业物联网（IIoT）通信协议的开发。这三大组织正在开发和推动共同标准，帮助提高生产效率，但是到现在为止，他们在自动化标准化的不同方面，是并行开发的。

Interoperability between devices and machines that use different protocols is a significant challenge in realizing the full potential offered by the Industrial Internet of Things. By collaborating on companion specifications to the standards and protocols they have already developed, OMAC, OPC Foundation, and PLCopen can help advance the quality and efficiency of data sharing and communication at the machine and production line and up through the enterprise. Collaborative efforts by standards organizations, such as OMAC, OPC Foundation, and PLCopen, align with the Industrial Internet Consortium's goal to ultimately identify and define building blocks for interoperability that help make smart factories and IIoT possible.

设备和机器不同协议间的互操作性，成为激发工业物联网最大潜能需要解决的一大挑战。在原有标准和协议的基础上，通过共同规范合作，OMAC、OPC基金会和PLCopen可以提高机器、生产线乃至整个企业之间数据共享和交流的质量以及效率。类似OMAC、OPC基金会和PLCopen等标准组织的协同努力，与工业互联网联盟（IIC）最终明确和定义互操作性构建模块的目标是一致的，都是为了推动智能工厂和工业物联网成为可能。

Here is how the three automation standards organizations are bringing their efforts together. One of OMAC's major initiatives has been promotion of the ISA-TR88.00.02 automation standard commonly known as PackML. The second generation was released last year. Manufacturers and machine builders worldwide have implemented ISA-TR88 on various control platforms to help increase speed to production, ease packaging line integration, and improve reliability. While PackML defines machine modes, states and tag naming conventions, it does not specify a communications protocol.

下面是这三大自动化标准组织正在合作的内容。OMAC其中的一项主要成果是ISA-TR88.00.02自动化标准，也就是俗称的PackML。其第二版本在去年发布。全球的制造商和设备制造商在各种控制平台采用了ISA-TR88，帮助提高生产速度，简化包装线的集成，并提高可靠性。虽然PackML定义了机器模式、状态和标签命名规则，但它没有指定通信协议。

The OPC Foundation's Unified Architecture (OPC UA) is an industrial interoperability framework. It delivers information modeling with integrated security, access rights, and all communication layers to provide plug and play machine-to-machine (M2M) communication inside factories. It is scalable across the plant floor and from sensor to IT enterprise and cloud scenarios. OPC and PLCopen recently worked together to define a set of function blocks to map the IEC 61131-3 global standard for industrial controls programming to the OPC UA information communication model. The latest version was released earlier this year. IEC 61131-3 is a global standard for industrial control programming and is recommended by OMAC in its Packaging Guidelines document.

OPC基金会的统一架构（OPC UA）是一个工业互操作框架，具备集成安全性、访问权限，以及所有通信层的信息建模，提供即插即用的工厂内机器对机器（M2M）通信。它可以扩展至整个工厂，从传感器到企业信息系统和云端。OPC和PLCopen最近正在开展合作，定义一组功能块，将IEC 61131-3工业控制编程全球标准映射到OPC UA信息通信模式。最新版本在今年早些时候发布。IEC 61131-3是工业控制编程全球标准，由OMAC封装指南文档推荐。

To take their efforts to the next level, OMAC and the OPC Foundation have established a taskforce to develop a companion specification for ISA-TR88/PackML and OPC UA by the end of 2016. The task force, led by Sari Germanos, open automation manager for B&R Industrial Automation, includes members of OMAC and OPC Foundation from around the world. Participation is open to interested members of either organization.

为了进一步携手，OMAC和OPC基金会成立了一个工作组，计划在2016年底之前开发出一项兼容ISA-TR88 / PackML和OPC UA的通用规范。这一工作组由贝加莱工业自动化公司的开放自动化经理Sari Germanos领导，成员来自世界各地的OMAC和OPC基金会，并对任何机构有兴趣的成员开放。
