Hello Glads; It has been a long time since I have seen that particular message on a Profibus network. Can you give us a copy of the diagnostic buffer of the CPU? To do so, open the diagnostic buffer screen, use the Save As.. button to create a text file containng all the logged messages of the buffer. You can attach this text file to your next reply in this thread. Can you tell us what version of PCS 7 you are running, and can you give us an idea of how long it has been installed? This message would appear when a CP 443-5 Profibus-DP master would lose access to some of the slaves in the Profibus network (the token ring mentionned in the message is the mechanism that gives priority to a DP master to connect with its configured slaves). See for example this (very old) thread, sugghesting how to set the bus properties (Profibus) on the CP 443-5 when that happens https://support.industry.siemens.com/tf/ww/en/posts/cp-443-5-problem/534 Hope this helps, Daniel Chartier |
