用的是光纤DP通讯,9号站ET200M报故障,大概1小时左右BF闪一次,时间不到1秒。随之这个站控制的设备就中断一秒后马上重启,硬件诊断,故障内容如下:
distributed i/os:station return
address of the affected dp slave: station number: 9
dp master system id:1
log. base address of the dp slave: input address: 8176
requested ob: rack failure ob (ob86)

(若干条省略,内容除了地址大致一致)
请老大们帮忙!
问题补充:
只是9#站报故障,8#,10#,11#都没事
最佳答案
1、address of the affected dp slave: station number: 9
requested ob: rack failure ob (ob86)
external error, outgoing event
I/O access error when updating the process image input table
P area, double-word access, access address: 80
从上述信息看,又BF闪,可能有下述原因引起BF(总线故障)闪:
、9号从站机架故障。检查模板的安装是否紧固;
、9号从站的供电电源的接线是否紧固;
、与PID80地址相对应的模板是否存在或是否正常;
、现场是否有强电磁干扰;
、检查光/电转换装置是否正常。
2、除了上述意见,建议:
、降低通讯速率,试试。
、如有条件可更换9号站ET200M的接口模块IM15X,试试;
