CI801 Cluster Modem Insert Error in CBM
On a running plant, I do have a problem inserting additional cluster modem CI801 under CI854 in Control Builder M Professional HW structure (5.1.1). I am getting an error message "This device could not be placed into the topology because of device specific rules."
I already have 12 clusters that are running fine. I also have some other profibus slaves under the same CI854 master (around 70 in total, incl. CI801). Have I reached maximum number of devices on the profibus master? See pictures inserted. I have some other CI854 masters where we run 16x CI801 with no problem and I can still add more. Can you advise whether there are some settings on CI854 or somewhere else that needs to be changed?
Attached is CBM session log with error lines.
