摘要
OPC UA是OPC基金会最新发布的用于工业自动化领域系统互连的规范。该文介绍了OPC UA的规格书组成,描述了OPC UA的传输机制与数据建模两部分基础组件。基于海上采油平台对仪控系统的实际要求,分析了OPC UA技术在海上采油平台的典型应用案例,并给出了具体的工程设计方案。同时,针对每个案例,总结了OPC UA相对于经典OPC规范的优势。
OPC UA is the latest standard provided by OPC foundation for system interoperability in the realm of industrial automation. This paper introduces the composition of OPC UA specification and describes transport mechanisms and data modeling of OPC IdA. Based on requirements for instrument control system in offshore oil platform, typical applications of OPC UA were analyzed and engineering solutions were given in detail. Besides, this paper summarizes the advantages of OPC UA over classic OPC standards in each case.
