Development and Research on Embedded Fieldbus Protocol Conversion Gateway
Profibus and CAN bus are two kinds of widely used field bus in the industrial control field. However, this two bus protocol conversion devices are not introduced on the market, it can not meet the needs of users. Therefore, the design of a Profibus and CAN protocol translation ngateway is very important. By comparing the OSI reference model, the same points of Profibus and CAN bus can be found, their communication model structure is streamlined by the OSI model, they are only three layers, which makes it possible to interconnect them. This paper designs an embedded protocol conversion gateway, S3C2410 processor is used as main controller, SPC3 and SJA1000 are selected as Profibus and CAN protocol chips. The design has realized Profibus and CAN bus protocol conversion, using this gateway in industrial field can bring certain economic benefits for the enterprise.
