OPC(OLE for Process Control)规范的出现为控制系统中独立单元的互连提供了标准,使控制软件可以高效、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。文中对OPC技术规范和特点进行了介绍,并且利用OPC技术,实现了WinAC与Ifix的连接,具有一定的实用性。
The rising ofOPC (OLEforProcessControl) specifications provides an standard for the interlink of unattached units in the control system, and enables the control software to do store-and-access operation of data efficiently and stably on the hardware equipment, thus greatly raising inter-operability and applicability of the control system. This paper discusses specifications and features of theOPC technology. And this technology could easily realize the interlink of WinAC and IFix, and thus is of practical significance
