Abstract

To connect converter to PROFIBUS,achieving motion control via fieldbus,by using modular design concept,a high-speed and intelligent PROFIBUS-DP communication interface board was designed and developed for the controller of a PMSM.In this board,a SIEMENS protocol chip SPC3 is adopted for high-speed serial data communication between PROFIBUS-DP master and slave stations.And a DPRAM is used for parallel data exchange between the modular and the intelligent controller.It is proved that the converter with this board can connect to PROFIBUS-DP as a slave station and achieve reliable high-speed communication with master stations.
