Abstract: Following an introduction to the method for plotting configuration pictures on host computer using the configuration software of Factory Talk View Site Edition (VSE), with the automatic control system of Yanjing Mine Coal Preparation Plant as an example, the paper goes to elaborate on the procedures for effecting RSlink data communication, online data reading and redundant configuration of host computer. Practice shows that the application of the software can lead to reduction of labor intensity, realization of automatic control of in-plant electrical and mechanical equipment, and hence cut-down of operating and maintenance costs.
