OPC技术规范把硬件供货商和使用软件开发者分别开来,使得两边的办公效率都有了很大提升。软件开发商无需理解硬件的本质和操作进程,就能访问OPC数据服务器中的数据,尤其是开发商在已使用了组态软件进行实时监控的进程控制系统基础上,用C++等高档语言开发系统时,大大简化了曩昔从设备传输数据的杂乱进程。在某铝厂的自动配料系统开发中,使用OPC技术方便地实现了VC使用程序和RSView32的数据交换,间接地实现了VC使用程序与PLC的通信,获得了很好的成果。OPC_Client.pdf
(OPC technical specification separates hardware suppliers from software developers, which greatly improves the office efficiency of both sides. Software developers can access the data in the OPC data server without understanding the nature and operation process of the hardware. In particular, developers can greatly simplify the messy process of data transmission from devices in the past when developing systems in high-end languages such as Cbased on the process control system that has used configuration software for real-time monitoring. In the development of automatic batching system in an aluminum factory, OPC technology is used to conveniently realize the data exchange between VC application program and RSView32, and indirectly realize the communication between VC application program and PLC, which has achieved good results.
