摘要
OPC(OLE for Process Control)基金会成立以来,OPC技术的发展经历了三个阶段,即经典OPC、OPC XML-DA和OPC UA(OPC Unified Architecture)。OPC技术从依赖微软的COM和DCOM技术到采用Web Services、XML和HTTP等标准和协议,实现了从依赖单一平台到平台无关的跨越。为了保持OPC技术的兼容性,OPC基金会提供了从经典OPC到OPC UA的迁移策略。最后,展望了OPC技术的发展前景。
The three main phases of OPC （OLE for Process Control） technology development are described that include Classic OPC and OPC XML-DA and OPC UA （OPC Unified Architecture） since the OPC foundation was founded. A leap from single platform to platform independent is realized that OPC technology base on from COM and DCOM to Web Services,XML and HTTP. For keeping the compatibility of OPC technology, the migration strategies are provided from Classic OPC to OPC UA by OPC foundation. Finally, the future of OPC technology is represented. Key words：classic OPC;OPC XML-DA;OPC UA
