摘要
本文以西门子S7-300系列PLC与智能流量计之间的数据通信为例,介绍如何实现Modbus和PROFIBUS—DP协议设备的相互通信,重点描述了上海泗博自动化的Modbus转PROFIBUS-DP网关PM-160在其中的应用,以及这两种不同通信协议的通信方式。
By taking the data communication between Siemens S7-300 series PLC and the intelligent flowmeters as an example, this paper introduces that how to realize the intercommunications between the devices respectively in Modhus protocol and in Profibus-DP protocol, with the intensive deseription of the application of gateway PM-160 for Modbus to Profibus-DP made by Shanghai Sibo Automation Co. in the conmmnication. And the communication modes of the two kinds of different communication pro- tocols are also described.
