With advancement in technology, the process control center and project site are always at different places in production, which makes remote monitoring system to be more and more widely used. At present, the field-bus control system (FCS) in the industrial control has been widely used. The subject will realize the long-range VVVF for motor by s7 field-bus control technology. In other words, the speed of the engine is set by Human Machine Interface (HMI) of Kingview installed in the host computer. The host computer and inferior machine communicate following the PROFIBUS-DP. The setting value is transmitted to remote inverter according to the USS communication protocol by the CPU module of S7 series PLC, thus, the speed will be achieved by the inverter; at the same time, the actual speed of the motor is returned to the host computer and displayed.
