| Abstract: | Taking the case of S7 - 200 programmable controller （SIEMENS ） , a communication method between PLC and FUJI frequency transformer is introduced in this paper, and appropriate software is developed and signal transmission process is tested. First, the design principles of PLC are interpreted, and then different states of the honing machine are shown by the reading and calculating of various index data for the honing machine with PLC; with proper process for several abnormal conditions, the optimum honing effect for the oil pump can be achieved. This communication system for honing machines is easily operated, accurately read without communication error. This system could be of higher value in application among similar products. |
