CPU315 2DP/PN 上电半个小时自动停机。
现象为 LED SF亮，同时CPU 处于STOP状态，其它从站，2个ET200M和EM227模块指示灯都正常。上电后再次重复。首先我把OB1里程序清空，还是会停机，说明我的程序没问题。停机时候模块指示灯都正常，所以请教高手指点，谢谢
诊断如下请大家帮忙分析

问题补充：
首先谢谢 半瓶醋 。
我加进去了OB86和OB122，出现的现象是不停机了，但是SF灯还是亮
3号从站配置如下
PS307 5A
ET200M 153-1AA03-OXBO 指示灯正常
DO 16*24 322-1BH01-0AA0 有输出
AI 8*13BIT 331 1KF02-OABO
AI 8*12bit 331-7kf02-oabo 2块，BF灯正常
AO 8*12BIT 332-5KF00 _OABO 2块 BF灯正常
检查了DP接线正确，但是屏蔽线割掉了，没有压到贴片上。
设备正在调试，只进行了数字量调试，还没有进行模拟量调试，我该怎么去检查，怎么处理？
最佳答案
Requested OB: Rack failure OB (OB86)
STOP caused by rack failure (OB not loaded or not possible, or no FRB)
Distributed I/Os: station Failure
从上述信息看，是机架故障：
、检查模板的安装，例如模板与机架之间的U型总线连接器、模板与前连接器的安装是否紧固。
、检查从站的通讯模块或接口模块的地址设定与组态的设定是否一致。
提问者对于答案的评价：
DP头从新做，接地也弄个专线。可能是干扰吧
