摘要
文章全面阐述了可编程序控制器控制系统中I/O点数的计算内容,指出点数计算过程中的注意事项及计算I/O点数的重要意义。在此基础上,针对可编程序控制器控制系统中常见的I/O点数不足问题进行分析,并结合笔者自身的工作经验,提出相应的I/O点数扩展方法,以期为可编程序控制器的更好应用奠定良好的理论基础。
This article expounds the content can be calculated the programmable controller control system I/O points, points out the important points attention and calculation of I/O points in the process of calculation. On this basis, analyze I/O points problems common PLC control system, combined with the author＇s own work experience, put forward the corresponding I/O number expansion method, in order to better application of programmable controller to provide and lay a good theoretical basis.
