降重：经典 OPC 规范的实现基于微软公司的 COM 和DCOM 技术完全依赖于 windows 系统平台不能在 Linux 系统下运行同时DCOM 难以配置并且不能用于互联网通信。OPC UA 相对传统 OPC 来说具有更高的可靠性、平台独立性、安全和访问控制功能等其基本组件是传输机制和数据建模。OPC UA 于2006 年颁布了最新的统一标准然后开始逐渐发展现在发展成为国际认可的开放平台统一通

Rewritten: The implementation of classic OPC specifications relies on Microsoft's COM and DCOM technologies and is limited to the Windows operating system, making it unsuitable for use on Linux systems. Additionally, DCOM is difficult to configure and cannot be used for internet communication. In contrast, OPC UA offers higher reliability, platform independence, security, and access control features, with its basic components being the transport mechanism and data modeling. In 2006, OPC UA released its latest unified standard and has since become an internationally recognized open platform for unified communication interfaces. From theoretical research to practical application, many scholars both domestically and internationally have conducted in-depth research on OPC UA
