你所贴出来的cpu报警信息仅仅是一部分,而且基本都是IO存取错误,这个应该是电磁阀动作干扰子站,造成子站模块丢失---这个只要看你的子站里面的模块地址是否就是信息里面的pqw520等等
真正造成停机的信息并不在你贴的这几条里面。
External error, Incoming event
外围问题啊,你可以一个个模块来试验
楼主你好,请查看一下你程序中的DB块,这些故障代码已经说的很清楚了,你所使用地址的数据类型不对,数据类型!看看你DB块中的分配类型是不是正确,尤其是基于FC105&FC106这2个程序块使用的DB块,问题就出在这里,别着急,仔细查看,你使用的简单类型还是复杂类型分配?
另外,在程序中插入OB85,OB121,OB122这三个,空的就行了,下载至CPU
希望可以帮助到你,如果还有疑问,把你程序打包发我邮箱,我帮你解决relyown@163.com
估计是你的fc105和fc106 作模拟量的时候有点问题,仔细看看硬件对应的对不对或者软件地址设置的对不对。
