Design of displaying system of measuring height for large-size closed presses

The working process of the large-size closed press requires exact location and closing height to meet the needs of processing,therefore a large-size closed press was designed based on SIEMENS S7-200 PLC and photoelectric checkout devices.The displaying system of measuring height of different models was adopted.And the Chinese text was used to show the type of different models and close height data in time through HMI TD200 man-machine interface so as to implement the location requests of closing height of models of the large-size press.The system is of good result when it is put into operation.
