PCS7组态300站与另外一个300站之间通讯出现问题，下面是我这边CPU的诊断信息，OB82,OB86,OB122等都在，CPU没有停机，我这边CPU诊断信息如下，请各位帮忙看看是什么问题，怎么解决，是他那边的问题还是我这边的。

问题补充：
麻烦说仔细点可以吗？我不是很懂，该怎么解决啊
最佳答案
1、从Diagnostic buffer中提示：地址为32#的分布式DP I/O从站故障，引起OB82、OB122的中断调用；访问I/O地址416、418、420、422、434、442出错。
2、但我不明白的是：你在CPU315-2 DP中使用了PCS7软件系统组态，这是真的吗？如果确信，那就是不兼容了！
3、PCS7软件系统是适用在S7-400以上CPU的。即便是S7-400以上CPU，也不所有的CPU模块硬件都匹配支持！

好像是其他问题，不过谢谢大家帮忙了……
