根据薄膜表面装饰工艺流程,采用西门子S7-200系列PLC对薄膜表面装饰设备的控制系统进行设计。首先根据程序流程图和顺序功能图,编写了PLC手动操作程序和自动操作程序,其中,自动操作程序分为连续循环和单周期。再通过热继电器和故障显示灯,实现电机的故障报错,最后采用力控软件对上位机界面进行仿真分析,其仿真结果能够较好的表现出整个薄膜表面装饰设备贴膜过程。
According to the film surface decoration process, the use of Siemens S7-200 series PLC film surface decoration equipment control system design. First of all, according to the program flow chart and sequential function chart, PLC manual operation program and automatic operation program were compiled. Among them, the automatic operation program is divided into continuous cycle and single cycle. And then through the thermal relay and fault indicator lights, to achieve the motor fault error, and finally using force control software to simulate the host computer interface, the simulation results can better reflect the entire film surface decoration equipment film process.
