摘要
OPC是微软OLE技术在工业控制领域建立的一套符合工业控制要求的通信接口规范。基于OPC规范,控制软件可以高效、稳定地对硬件设备进行数据存取操作,极大地提高了控制系统的互操作性和适应性。OPC将现场信号按照统一的标准与控制管理软件无缝连接,将硬件和应用软件有效地分离。
OPC is a set of communication interface norms which are established on the basis of Microsoft OLE technology in the industrial control field and which accord with the requirements of industrial control. According to the OPC norm, control-software can efficiently and stably carry on a data access operation to the hardware equipment and greatly improve the mutual operability and adaptability of the control-system. The OPC technique connects the spot signal to the control-management software according to the uniform standards, and also effectively separates the hardware from the internet application software.
