【Abstract】 The capacity and feature of a large-sized switched apparatus station are presented in this paper. A monitoring and control system is designed for this station with industrial PC as upper computer and PLC as lower computer. The testing process and programming philosophy of switch apparatus testing are discussed in detail. WinCC configuration software with a human-machine interface (HMI) is used to select the testing circuit and acting switches of switch apparatus flexibly, and monitor the dynamical testing process. The data exchange is also described between upper and lower computer. The monitoring and control system has been run successfully in the field.更多还原
