摘要
随着低压电器的智能化发展,越来越多的电器产品支持Modbus现场总线控制技术。在LabVIEW中采用NI Modbus程序库能实现对ABB-ACS550变频器基于Modbus协议的通信,从而实现对电机系统的调速控制。试验结果表明采用Modbus通信控制技术不仅能充分完成调速任务,并且控制精度高、节约电器通道、抗干扰性好。
With the intelligent development of low-voltage electrical appliances,more and more electrical products support Modbus fieldbus control technology.In order to achieve the goat that changing the speed of the motor,it is in LabVIEW that realizing the communication between IPC and Inverter,which use NI Modbus library.Experimental results show that this kind of communication control technology not only can fully complete the control task,but also have high control precision,appliances channel saving and good anti-interference.
