在组态概念出现之前，要实现某一任务，都是通过编写程序（如使用BASIFORTRAN语言等）来实现的。编写程序不但工作量大、周期长，而且容易犯错误，不能保证工期。组态软件的出现解决了这个问题，对于过去需要几个月的工作，通过组态几天就可以完成。组态软件一般有三种，其英文简称分别为hmMMI和SCADA。目前组态软件发展迅猛，已经扩展到企业信息管理系统、管理和控制一体化、远程诊断和维护以及在互联网上的一系列的数据整合。

一定条件下，我们可以在输入端做出“人为动作”，来迫使输出端作出相应的反应。其实任何器件，都不难找到相应的检修和判断方法，器件的正常工作与否即使如雪泥鸿爪，也总会“有迹可寻”。为此，需要研究触发器的输入电路形式，并据此采用相应的“人为动作”，而不会导致在线器件（如触发器的前级电路）的损坏。对器件检测的方法，是上电检测输入、输出状态得出结论，远比测量引脚电阻、摘下后放入IC测试仪进行检测，更为方便和准确。
