The main drag of commonly used high-power DC motor speed control means in addition to a few continue to use the F-D unit in the form, most completed in the 1980s the first step in the transformation. Stepless speed range of the PLC control unit to drive the servo motor instead of the original pure mechanical variable speed, and then reached in the case without reducing the performance of mechanical transmission, simplifying the mechanical drive system, improved the performance of the machine operator. Successfully applied in heavy-duty roll lathe.This article introduces a touch screen PLC control system in the bed of the C84-type roller vehicle, including the composition of the rolling roll lathe the parameter descriptions, control systems constitute and selection bar roll lathe of hardware terminal, the PLC input / output address allocated, touch-screen picture of theconfiguration, PLC ladder program instruction list program and the PLC and touch screen communication. The introduction of the roll lathe PLC and touch screen, we become more familiar with PLC and touch screen design and pay attention to problems in engineering applications.Key words: Roll lathe; PLC; touch screen; ladder ;Configuration
