OPC Foundation, PLCopen and OMAC start OPC UA communications collaboration
OPC基金會，PLCopen和OMAC啟動OPC UA通信協(xié)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.

機(jī)械自動化與控制組織（OMAC），OPC基金會，和PLCopen正在共同努力，以幫助進(jìn)一步推進(jìn)工業(yè)物聯(lián)網(wǎng)（IIoT）通信協(xié)議的開發(fā)。這三大組織正在開發(fā)和推動共同標(biāo)準(zhǔn)，幫助提高生產(chǎn)效率，但是到現(xiàn)在為止，他們在自動化標(biāo)準(zhǔn)化的不同方面，是并行開發(fā)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.

設(shè)備和機(jī)器不同協(xié)議間的互操作性，成為激發(fā)工業(yè)物聯(lián)網(wǎng)最大潛能需要解決的一大挑戰(zhàn)。在原有標(biāo)準(zhǔn)和協(xié)議的基礎(chǔ)上，通過共同規(guī)范合作，OMAC、OPC基金會和PLCopen可以提高機(jī)器、生產(chǎn)線乃至整個企業(yè)之間數(shù)據(jù)共享和交流的質(zhì)量以及效率。類似OMAC、OPC基金會和PLCopen等標(biāo)準(zhǔn)組織的協(xié)同努力，與工業(yè)互聯(lián)網(wǎng)聯(lián)盟（IIC）最終明確和定義互操作性構(gòu)建模塊的目標(biāo)是一致的，都是為了推動智能工廠和工業(yè)物聯(lián)網(wǎng)成為可能。

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.

下面是這三大自動化標(biāo)準(zhǔn)組織正在合作的內(nèi)容。OMAC其中的一項主要成果是ISA-TR88.00.02自動化標(biāo)準(zhǔn)，也就是俗稱的PackML。其第二版本在去年發(fā)布。全球的制造商和設(shè)備制造商在各種控制平臺采用了ISA-TR88，幫助提高生產(chǎn)速度，簡化包裝線的集成，并提高可靠性。雖然PackML定義了機(jī)器模式、狀態(tài)和標(biāo)簽命名規(guī)則，但它沒有指定通信協(xié)議。

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基金會的統(tǒng)一架構(gòu)（OPC UA）是一個工業(yè)互操作框架，具備集成安全性、訪問權(quán)限，以及所有通信層的信息建模，提供即插即用的工廠內(nèi)機(jī)器對機(jī)器（M2M）通信。它可以擴(kuò)展至整個工廠，從傳感器到企業(yè)信息系統(tǒng)和云端。OPC和PLCopen最近正在開展合作，定義一組功能塊，將IEC 61131-3工業(yè)控制編程全球標(biāo)準(zhǔn)映射到OPC UA信息通信模式。最新版本在今年早些時候發(fā)布。IEC 61131-3是工業(yè)控制編程全球標(biāo)準(zhǔn)，由OMAC封裝指南文檔推薦。

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.

為了進(jìn)一步攜手，OMAC和OPC基金會成立了一個工作組，計劃在2016年底之前開發(fā)出一項兼容ISA-TR88 / PackML和OPC UA的通用規(guī)范。這一工作組由貝加萊工業(yè)自動化公司的開放自動化經(jīng)理Sari Germanos領(lǐng)導(dǎo)，成員來自世界各地的OMAC和OPC基金會，并對任何機(jī)構(gòu)有興趣的成員開放。
