Abstract:According to the forming processing requirements of arc plate,the network construction among the master PLC and the remote station ET200S and touch screen HMITECH TPC150TC in the hydraulic press control system was built. The master PLC and touch screen software programs were designed, focusing on the main pump motor soft start and data processing and setting, while the touch screen configuration was explained. Through onsite master PLC acquiring and analyzing data,the control executive functions of press down, pressure, stopped , return ,fast back were achieved. After debugging and application, each functional block runs exactly, the expected function can be completed.
