| Abstract: | Being a kind of field bus, Profibus-DP has a broad application in industrial field. The development of communication adapter between Profibus-DP and RS232/RS422/RS485 are introduced in the paper. Based on MCU and SPC3, how to design hardware circuit and software are illustrated in detail. It is found that the communication adapter has the data transfer function, and it is groundwork for open intereonnection and distributed control with system. |
