以上工作中，复杂的系统规划可能需要几天甚至更长的时间，但一个简单的系统规划在一个具有良好的职业习惯的编程工程师手中，可能只需要几个小时。
这里要强调一个问题，是十分简单但却几乎每个项目都会发生的，那就是对PLC的接线。这往往是经验不足的工程师常常忽略的一个问题。其实，现场调试大部分的问题和工作量都是在接线方面。有经验的工程师首先应当检查现场的接线。通常，如果现场接线是由用户或者其它的施工人员完成的，则通过看其接线图和接线的外观，就可以对接线的质量有个大致的判断。然后要对所有的接线进行一次完整而认真的检查。现场由于接线错误而导致PLC被烧坏的情况屡次发生，在进行真正的调试之前，一定要认真地检查。即便接线不是你的工作，检查接线也是你的义务和责任，而且，可以省去你后面大量的时间。
