姑苏城外:
我在往卡上写的时候选的是菜单plc下的save to memory card，然后弹出的对话框中save current user program为已勾选的灰色，不能更改，但是我根据设备厂家的建议没有勾选current project，也没有附加任何文件保存到卡上。用save to memory card功能，存储卡就只能在cpu0上，所以我把两张卡都先后插入cpu0上写了一次。写完后把cpu0断电，重启后清内存，在用step7比较了块文件的一致性。

dcount107:
414-4h的ur2-h机架0和1上都各自插了两个sm421 di模块和一个sm422 do模块。

我从cpu1上保存的诊断缓冲区里面看到这么一条，不知道是不是故障原因，请各位帮忙看一下：
