Greetings. I have a profibus DP network integrated by a S7300 as a master a few slaves, including a station commanded by a ET200S (IM 151-1 STANDARD). The modulo goes to fault but there is no I/O module with problem. The SF led flash 3 times and the BF 8 times, continously.. We haved checked changing the module, measuring 24 volts, earth cables, disconnected cables... Don´t know what else to do, every I/O including the other nodes seems to be working ok. For now I don't have acces to a laptop with step 7 to read buffer diagnostic. In your experience what could be? In this station with the ET200S faulted the IO phisically shows no error. Everything is on green, Attachment20171003_044842.wmv (452 Downloads) |

Hello again, this is the buffer diagnostic of the event. Can you help me read this and maybe tell me something that could help me? Thanks. AttachmentDiagnose0041.txt (487 Downloads) |
