1771-NIV浙江余姚

在现代化的工业生产中,大量采用了可编程序控制系统,可编程序控制器能在恶劣
的工作环 境下正常工作,但其构成的控制系统由于设计、安装、干扰等因素有时会
出现故障。有些问 题是在系统设计时考虑不周造成的。根据实践中的经验和教训,
本文阐述可编程序控制系统 设计时应注意的问题。
1、一个系统中使用的成熟技术至少应占到75%以上
“成熟技术”一是经过一定的生产实践考验的可编程控制器产品或类似设计,或者确
定能在未来的生产实践中,经得起考验;二是设计工作人员对于需要使用的技术要有
经验或有掌握它的能力。设计与配置一个可编程序控制系统选用的技术与设计方案切
实可行。因为一个生产过程控制系统,一旦做出来,要长久使用下去,难以找到机会
反复修改。设计的硬件系 统和编程软件,其中某些缺欠,可能一直隐藏在已完成的
系统中。若遇到发生破坏作用的条件,后果难以预料。
