The hottest real open standard, new generation OPC

True open standard new generation OPC specification OPC UA

editor's note: it was learned from the technical exchange meeting of OPC China Association that the new generation OPC specification OPC UA has been established. OPC UA is based on the first generation of OPC technical specifications, transforming OPC from Microsoft centered com/dcom technology to open standards, and unifying various OPC technical specifications N the technology used to confirm the performance of a method should be one of the following cases, or a combination of them: et's brand-new communication architecture, easy to configure and maintain, enhanced visualization, higher reliability, security and scalability, so that OPC is widely used in workshops and even the entire management information system

gkong news on October 21, in order to better clean OPC related knowledge among Chinese users and deal with data later, so that suppliers can reduce development costs and risks, and end users can easily apply various automated equipment systems, the OPC new technology seminar organized by OPC China foundation was successfully held in Guangyun hall 8 of Everbright Hotel, and many professional audiences attended the meeting

Guo Wenzhe, member of OPC Foundation China Promotion Committee and Ni R & D Manager, made a speech

at the meeting, Guo Wenzhe, member of OPC Foundation China Promotion Committee and R & D Manager of national instruments, explained in detail to the audience the challenges faced by the integrated system at this stage, the necessity of OPC UA (unified architecture), the new standard of OPC, the advantages of OPC unified architecture and the future development trend of OPC. Guo Wenzhe said that on the basis of the first generation of OPC technical specifications, opc-ua has transformed OPC from Microsoft centered com/dcom technology into open standards, and unified various OPC technical specifications Net new communication architecture, easy to configure and maintain, enhanced visualization, higher reliability, security and scalability, so that OPC is widely used in workshops and even the entire management information system

in order to extend the perspective of OPC to the whole enterprise, OPC UA specification defines many aspects of the interface, including complex data model, unified information semantics, security and redundancy. The specification can provide basic general provisions. More importantly, it provides a standard method to expand the information model. At the same time, it also provides comprehensive certification to ensure interoperability in the implementation process. OPC UA is a comprehensive specification rather than a detailed introduction of the interface. Users can get the basic support of security, redundancy, domain navigation and rich information model

Xu Jun, the OPC product manager of Beijing yacon, who is responsible for the market promotion and related training of domestic OPC technology, shared the experience of yacon with the audience on the development and application of OPC in the energy management of the metallurgical industry. Over the past 12 years, Asian control has been committed to the development of OPC, hoping that through the sharing of its own experience, more OPC manufacturers can avoid detours, save unnecessary investment, and promote OPC to make outstanding contributions to new technologies and standards

Ms. Jane, product manager of matrikonopc company from Canada, introduced in detail the hub spoke historical data communication structure based on OPC - decentralized historical data storage and analysis.

Ms. Jane said that matrikonopc will soon set up a representative office in China, which also means that the majority of Chinese users will be able to get more convenient and fast technology in the near future. 4. The hydraulic system should be installed safely to regulate pressure; Technical support and service

zhangtiangui, Secretary General of OPC (China) foundation, said that OPC China Promotion Association will work together with domestic member manufacturers to popularize OPC related knowledge among Chinese users more widely, so that more domestic manufacturers can make good use of this tool and gradually promote Chinese automation companies to the world

it is understood that OPC (OLE for process control) is an industrial standard. The international organization that manages this standard is the OPC foundation, which has more than 220 members. All over the world, including all major companies of automatic control systems, instruments and process control systems in the world. Based on Microsoft's OLE (now active X), com (component object model) and DCOM (Distributed Component Object Model) technology. OPC includes a set of standard sets of interfaces, attributes and methods for process control and manufacturing automation systems
