ACS880多传动根据共用直流母线配置原则设计，可让多台变频器共用一个电源和公共制动装置。供电装置有多种选择，可以是简单的二极管供电单元，也可以是高度复杂的有源前端IGBT供电单元。
多传动适用于由多台电机驱动的应用。它们采用共用直流总线设计，可让多台变频器共用一个电源供电。共用直流总线设计可以节省能源和成本——因为不是所有电能都必须通过电网获取，并且使变频器的供电整流单元尺寸可以更小。连接一根电源线和共用一个电源可以减少布线数量，节省占地空间以及投资和维护成本。

control automation industry has developed a mature cloud configuration system, in accordance with the habits of industrial control automation engineers, can develop a good monitoring platform system, directly into the network platform and mobile APP monitoring. Based on the mature cloud configuration webgui of Guangzhou Giant Electronics as the development basis, this paper completely introduces how automatic control engineers do mobile phone APP to remotely monitor PLC.
I. PLC system data acquisition and communication
The traditional configuration and PLC communication adopt Ethernet, 485, 422, 232 and other communication methods, which need to be connected by wire. Because the position of mobile phone or network terminal is not fixed, so the traditional data acquisition method is not suitable, so the PLC control system needs to add a network data acquisition module. WEBGUI is the use of a large control GRM series remote control module
