Hi habeichnichtwirklich, I never seen this kind of message, but i recommend to you check this information to see if you meet the requirements: What are the requirements for operating OPC in connection with WinCC (V7 or Professional)? |
If this information really helps, you could use the Rate function. |

It looks like the default DP Group OPCUAAlarm is not present in your project (anymore). By default this group is read to determine which alarms the OPC UA server should expose to the connecting systems. |

I guess that is by design, because the documentation contains this remark: Note that the OPCUARead, OPCUAWrite, OPCUAAlarm and OPCUAHARead groups may not contain subgroups. If a subgroup was added to one of these groups an error message is shown and the subgroups will be ignored. It looks like you only have a single subgroup, so you could remove the alias from the current dp group and assign it to the subgroup. |
