CI854 Warning: "Taken out of ring by naother master, check system conf."
One of my CI854 Profibus Master devices generates a lot of warnings with the following message: "Taken out of ring by another master, check system conf."
Does anybody know why this warning appears?
A few years ago, I've faced with that problem.
In our plant, earthing system was not good enough, so from time to time that message was appearing. Also sometimes CI854 Master card lost communication to drives or ı/o modules.
We've enforced earthing system, and got rid of that problem.
Hope it helps you.
