Modbus RTU Communication Control Example Between S7-200smart and Mitsubishi F700 Inverter
In order to improve efficiency and save costs,a method of Modbus RTU protocol communication between Siemens S7-200smart and Mitsubishi F700 inverter is introduced.Modbus RTU communication does not need to occupy I/O points,and the wiring is also relatively simple.After the steps of hardware connection,communication network setting,data reading and writing,master station programming,the communication network between the master station and the slave station is established.After testing,S7-200smart can control the start,stop and frequency of the F700 inverter,achieving the purpose of controlling the flow of the water pump.
