摘　　要：首先介绍了MODBUS/TCP工业以太网协议和PROFIBUS-DP现场总线协议。从理论角度探讨了协议转换的实现方法,利用协议互补法原理研制出嵌入式MODBUS/TCP工业以太网与PROFIBUS-DP现场总线协议转换器。The paper gives an introduction about the MODBUS/TCP industrial ethernet protocol and the PROFIBUS- DP fieldbus protocol, and discusses the realization of protocol conversion in terms of theory. The paper also presents the development of an embedded protocol converter between the MODBUS/TCP industrial ethernet and the PROFIBUS - DP fieldbus, and analyses the principle of the mutual protocol and the method to realize it.
