摘要
研讨罗克韦尔PLC与施奈德71系列变频器之间的通讯问题,通过DeviceNet网络对变频器的参数在线实时读取,从而可以得到变频器的实际转速、频率、力矩、功率等参数,并可以实现对变频器参数在线设定,以达到通过通信的方式对电机实时控制的目的,进而满足不同行业的特殊要求。
The paper introduces the communication between AB PLC and Schneider 71 Inverter. The PLC can read the parameters of the inverter across DeviceNet, so the PLC will get the rotational speed, frequency, torque,Power and so on. And it also can change the parameters of it online. So it will achieve the target to control the motor online through the communications,and then it will satisfy some special needs in different Majors.
