Match usage of CNC M command and PLC ladder diagram

在数控机床中,M指令与PLC梯形图配合使用可使系统的设计、使用更加方便;进而对这种使用方法进行探讨,并以西门子SINUMERIK802系列数控系统为例介绍了实现方法。

Match usage of M command and PLC ladder diagram can make a systems design and usage more convenient in CNC machine.The paper discussed this method,at the same time, the Siemens SINUMERIK 802 series CNC system is used as an example to introduce in detail.
