【摘要】 用PLC和开关量模型组成机电一体化的起重机模拟系统,可以模拟起重机控制系统的实际工作情况。不仅适用于PLC控制系统的程序调试、软件开发,同时为系统设计带来很大方便。它以PLC和模拟控制板组成模拟运行系统,通过I/O地址分配表,编排I/O状态流程图,给出系统梯形图。更多还原

【Abstract】 The electromechanic integrated crane analog system,which is composed of PLC and descrete devices,is able to simulate the actual working situations of the crane control system.The system not only applies to program debug and software development of the PLC control system,but also brings significant conveniences to the system design.With PLC and analog control panel composing the analog operating system,the crane analog system edits I/O state flow chart and gives systematic ladder diagram with the help of I/O address allocation chart.更多还原
