| Abstract: | This paper introduces a control system for vitriol feeding composed of PC and Siemens PLC and frequency-converters. The serial communication between PLC and frequency-converters is realized based on the USS protocol of the RS485 interface. Parameters of frequency-converters can be set on the BiCo which can flexibly combine the function of input with the one of output. The paper also discusses the method and the program of controlling frequency-converters based on the USS protocol. The presented system is very convenient to monitor the parameters of every frequency-converter on line and realize the telenet control. The method can reduce electric connections and improve the anti-jamming capability of the system. Thereby a scheme for vitriol feeding in water plate with low-cost and high-performance is provided. |
