Hello memol; Start by having a look at this page from the CPU 410-5H system manual, explaining the meaning of th different signals of the diagnostic LEDs that are active in your project (other sections of the manual should eventually prove interesting as well, keep a copy): https://support.industry.siemens.com/cs/ww/en/view/74736822/71172375051 So basically the CPU is telling you that you have an active fault, from outside the CPU, and in the first Profinet interface network. And the fault is still present, or the CPU LEDs would have gone out. It could be interesting for you to have another look at your diagnostic buffer, searching for calls to OB 86 (remote I/O faults) in the logged messages. That would point out the I/O module pr equipment on Profinet that signals an issue, even if it is intermittent. If you require more help in understanding the messages, please use the Save AS,, button you can find in the diagnostic buffer screen, which will generate a text file including the logged messages from the buffer, and post that file here on the forum. That would allow us the chance of examining the messages, and maybe finding something that could help you out. Hope this helps, |
