| Abstract: | OPC(OLE for process control) is an international standard for industrial automation software interface based on component object model.Along with the development of industrial control,the OPC technology reaches its maturity,and is widely applied in industrial systems.This system connects input and output variables of PLC with Delphi components,and so implements the monitor of host computer to Siemens PLC.Experiments results show that the system's performance is stable,reliable and it works well. |
