我这有一套CPU 414-3 DP故障停机。附件是诊断信息和CPU模块指示状态。
hard online error.jpg是我试图硬件online的时候的错误提示的截图。
复机操作如下:
1、先保存了诊断信息,CPU stop状态,不能RUN。
2、试图上载PLC程序没成功,试图PLC在线没成功
3、试图硬件组态在线没成功
4、在CPU STOP的情况下尝试重新下载硬件组态,下载硬件组态之后,PLC报警消失,各红色指示灯消失,但是上位机还是未连接到的状态;
5、PLC在线发现程序是空的,又重新下载了程序,系统恢复自动
6、协助业主恢复系统运行

问题补充:
请特别注意诊断信息
Event 118 of 120和Event 120 of 120
这两个信息应该是问题的起始。

最佳答案
请问一下CPU的STOP灯是不是在慢闪,如果一直在慢闪,那是MMC卡在请求被动格式化,出现这种情况是有可能MMC卡内的程序出现意外问题。先备份好程序,然后请复位一下MMC卡,如果程序被清空后重新下载一下,试试看。下面是被动格式化的步骤:
(可以执行被动格式化的标志为CPU 的STOP 灯出现慢闪,这是CPU 在请求被动格式化,
只有此时可以用MRES 按钮格式化MMC 卡,把卡中的错误信息清除,具体操作方法如下:
将模式开关拨到MRES 并保持直到STOP 灯保持常亮(约九秒),并在其后三秒内迅速拨动
模式开关,即在三秒内使模式开关返回到STOP 后再迅速拨回到MRES 位置,此时,STOP 灯
快速闪烁,表示正在格式化。保持开关在MRES 位置,直到STOP 灯常亮,格式化完成。
注意:一定要使用规定的操作顺序。否则,MMC 就不能进行格式化,而是返回存储器复位状
态。这种情况是在CPU的STOP 灯慢速闪烁时使用,是一种被动的格式化,在正常使用的情况下
无法用MRES格式化MMC卡。)
提问者对于答案的评价:
问题早已解决,现在才来回复对不住。
专家置评
S7-400系列的PLC无MMC卡,MMC卡是S7-300PLC用的。
