 |
|
Hi. I have an issue with the Control Net module 1756-CN2R that keeps generating 'Duplicate Node Detected' (DND) in random ControNet nodes in the entire star redundant network which retains until the module is power recycled.The only way to get rid of the "DND" is to recycle power at the affected nodes. Please find the attached configuration for the source of duplicate node detected error. I have all fiber module 1786-RPFRXL v2.005 and RPA/B. There redundant system. Remote chassis connected by optics. Periodically there is a network failure, resulting in loss of the node (s) network. Maybe someone faced with a problem.
I tried to change the settings configuration RSNetwoRX media configuration - does not help.

Наш "пострел" везде поспел!
Припекло, видать...
На плцфорум.уз.уа ещё не написали? 
Там тоже толковые спецы обитают. |

| Yes thank you. I found this topic. I pointed out to the media configuration RSNetWORX cable length and type cable, as well as converters and repeaters. It did not solve my problem ( |

Thank you for your help. The problem was solved, it was in the optical cable. More precisely in the connector. The attenuation in the natural range, but in microscopy - seen strong contamination. Well, that was found specialist equipment at the facility.
P.S.Topik can be closed. |
