PLC Control System of Cutting Fixed-length Plates and Simulation Debugging

摘要

PLC (programmable logic controller) is one type of general industrial control platforms. Based on the PLC of SIMENS S7-200 series, this paper introduces a control scheme of cutting metal plates' control system in the flame cutting machine. The hardware design and PLC program are given in details, which achieve accurate position and fixed-length cutting by the stepper motor through the control of PLC. In addition, the configuration simulation of the system is performed by the application of King view software. The control system has multiple operating modes, high reliability, stability and is able to meet the variety of different work requirements. The automatic control of cutting metal plates is achieved. The control system is applied to actual projects and can greatly enhance productivity.
