The application and research of the liquid level control technology used in mineral flotation process which based on the modbus communication protocol

Flotation level control is a very important part in the flotation mineral separation process. This article introduces one application of the Modbus RTU protocol which used in the flotation liquid level control system, discusses the S7-300's programming ideas and methods which based on the form of communication, and optimize the communication strategy. The practical application shows that the system of flotation liquid level control which based on Modbus RTU protocol can get better control effect, and ensure a good target for the mineral separation.
