PCS7組態(tài)300站與另外一個(gè)300站之間通訊出現(xiàn)問題,下面是我這邊CPU的診斷信息,OB82,OB86,OB122等都在,CPU沒有停機(jī),我這邊CPU診斷信息如下,請(qǐng)各位幫忙看看是什么問題,怎么解決,是他那邊的問題還是我這邊的。

問題補(bǔ)充:
麻煩說仔細(xì)點(diǎn)可以嗎?我不是很懂,該怎么解決啊
佳答案
1、從Diagnostic buffer中提示:地址為32#的分布式DP I/O從站故障,引起OB82、OB122的中斷調(diào)用;訪問I/O地址416、418、420、422、434、442出錯(cuò)。
2、但我不明白的是:你在CPU315-2 DP中使用了PCS7軟件系統(tǒng)組態(tài),這是真的嗎?如果確信,那就是不兼容了!
3、PCS7軟件系統(tǒng)是適用在S7-400以上CPU的。即便是S7-400以上CPU,也不所有的CPU模塊硬件都匹配支持!
