Abstract
 In recent years, used the automatic equipment along with the more and more manufacture enterprise to carry on the production processing, the control system based on PLC And touches the screen technology gradually to apply to the control engineering domain. This topic is through OMRON Corporation's PLC control technology and touches the screen technology to control the high tonnage presswork. The compilation trapezoidal chart procedure, through accepts the switch quantity, the simulation quantity input, After processing power take-off valve quantity, simulation quantity control relay movement. Prompt is accurate to the compressor each kind of movement realization and the process control. Touched the screen technology simplify the operation, enhanced the control reliability. Cold Compress Control System Based on PLC and Touches the Screen Technology, Has realized the multi-purpose control, reduces the artificial laboring tensely, enhances the production efficiency, safe reliable, is easy to operate.
