Hi everyone,

Please support me on this issue!

Recently, my PLC system has been experiencing an issue where it occasionally loses I/O redundancy for both racks 8 and 9. I have already replaced all the Profibus cables, connectors, and the Profibus converter, but the problem persists.

Attached is the diagnostic buffer. When the issue occurred, the SF and BF LEDs were blinking. Could anyone help me verify this issue? I suspect the problem might be related to the incorrect configuration of Profibus address No. 10, as it is not being used in my system (please check the attachment).

Thank you!
