但是到了隔天的时候，却收到了因为吸烟而进行罚款的通知，并且总共罚款下来是2000块钱，当时老王心里就感觉到特别的郁闷，明明自己是躲起来偷偷的吸烟的，为什么还会被查出，并且还收到这样的通知，后来厂长将手机拿出来，里面就是老王在偷偷进行吸烟的视频，于是老王就明白了，自己被厂长所盯住了，可能也是因为工资高于其他人的原因，所以老王也做出了一个决定，直接辞职，因为拥有一身技术，所以他的新工作找得非常顺利，并且很快入职。

也可以要一些程序。比较全的项目资料。图纸，工艺，程序。书的话，一二百块钱。如果网上下载的pdf文档了。版权所有。如果自己不是很喜欢，PLC也没有买的必要了。3，如果自己确实比较喜好。有很多仿三菱，仿西门子200的PLC，指令一样的，要便宜一半的钱。当然有钱也可以买原装的。三菱，西门子仿的数据线，淘宝上也有卖的。一套下来。花个2000来块钱也可以。培训机构不推荐。如果想从事这一行，先从维护做起。
