西门子变频器的应用西门子变频器的应用第4讲西门子SINAMICS S120变频器与HMI直接通讯

摘要

在工业应用中，HMI包括触摸屏和组态软件。在一般情况下，人机界面都是与PLC相连，但是没有PLC，HMI也可以与变频器相连。本文主要阐述了西门子SINAMICS S120变频器与HMI直接通讯。%In industrial applications, the HMI includes the touch screen and the configuration software. Under normal circumstances, the human-machine interface is connected to the PLC. But without PLC, the HMI can also be connected to the inverter. This article describes Siemens's SINAMICS S120 Inverter and the direct communication with HMI.
