我们在设计小型的PLC控制系统时,常常会需要在外部改变PLC内部的数据,譬如Counter, Timer或者Data的值,以适应生产过程的需要。而且要求系统关机以后,这些数据还能够保存在PLC内部,当下次开机后,这些数据可以被调出继续使用。
现在许多小型的PLC都或多或少地提供了掉电保持寄存器,以便在PLC断电的时候,保存用户想要保存的数据。但大多数时候,PLC制造厂商为了节约成本,不可能提供足够数的掉电保持寄存器供系统设计人员使用,所以当被调整的数据项目超过PLC内部的掉电保持寄存器的数目的时候,我们不得不减少被调整的数据项目(固定或不用)或者购买具有更多掉电保持寄存器数目的PLC,这样的话,就使得生产机械缺乏灵活性和适应性,从而降低产品档次或增加成本。
