众所周知,目前我国75%的生产机械设备,都是采用继电器控制,除了可靠性差外,设计程序也很繁杂。从方案的确立到技术条件的设计以及施工的设计,图面的工作量很大,这势必造成设计周期长。而采用PLC控制可以大大缩短设计周期,甚至有些文件资料也不必绘制成图。设计人员完全可以利用编程器上屏幕显示来输入,或修改程序使得梯形图能准确无误地反映生产要求。编程人员也可根据新产品对生产提出的新工艺要求,重新编写程序并把它存储在EEPROM模块中去,需要加工哪个产品的程序,操作人员可以随时调用,这既方便、简单又可保密。开发这种软件对优化生产过程,提高产品数量和质量,提高劳动生产率,非常具有实际意义。仅此一点也深受生产及设计者的欢迎。
