【Abstract】 This paper presents a design method of an OPC client in Visual Basic based on C/S modal.By the OPC clientwe can acquire WinCC tags in the WinCC project from the WinCC OPC serverthe concrete steps and programs are offered in details.The method has been successfully applied the monitor and control system of motor-testingand solved the datum transference problem from WinCC to SQL database.At lastthe results of operation show that the control system has achieved the performances and satisfied the demands of factoryand it works steadily.更多还原
