摘要
本文以三菱公司的FR—A740变频器为例,讨论了西门子S7—300系列PLC与三菱FR—A740变频器通过Profibus—DP现场总线实现数据通讯的方法。通过它在某生产线中的应用,从而使该方法得到了实践验证,为后续建立变频器的集中监控打下了基础。
By taking the FR-A740 frequency converter made by Mitsubishi Company as the example, the approach to realize the data communication between Siemens S7-300 series PLC and Mitsubishi FR-A740 frequency converter through Profibus-DP is dis- cussed in this paper. Morenver, by means of its applicalinn in some production line, thus the approach has been verified practically in order to lay a foundation of centralized monitoring for frequency converter subsequently.
