Hello DesignTech, I have experienced something similar and the reason was a 380VAC VFD cable laid beside theProfibus cable. When Profibus cablerout was changed, the problem was gone for good. Don't forget to check termination resistors. Maybe it's not your case but just check Profibus network installation. Such problems are mostly caused by violating the rules of network installation. Best regards. H-H |
