一种车床 S7 系统 PLC 设计摘要：PLC 即可编程控制器，在数控车床控制系统中应用 PLC，可以使机床控制变得十分简单，且方便维修，便于检查。本文基于此完成了使用 S7 系统 PLC 车床主要控制电器的设计、控制系统的设计、系统软硬件设计。此外依据需要确定了 PLC 的 I/O 地址分配，设计了梯形图并通过程序的仿真与调试，以实际结果证明设计效果优良。关键词：车床；PLC；控制系统A machine S7 PLC system designAbstract:PLC can be programmed controller, used in CNC lathe control system PLC, the machine control can become very simple and easy maintenance, easy to check. Based on this complete system using the S7 PLC lathe main electrical control design, control system design, system hardware and software design. Also according to the needs identified by the PLC I / O address assignment, design and simulation and debugging ladder program, the actual results show that good design effect.Keywords:Lathe; PLC; Control system目录.........................................................2...............................................2.......................................3.........................................4.......................................................5.................................................5.......................................................5.......................................................5...................................................6.......................................................6.................................................6.......................................................6.............................................6..................................................7.......................................................8.................................................8.....................................................8.....................................................9.......................................................9..............
