Hi there

I can't start the OPC UA Server. I have the following errors in logviewer:


OpcUaSManager in Funktion connectGroup, Verbindung zu Gruppenalias @OPCUAAlarm nicht möglich
...
OpcUaSManager::processValueChange Answer invalid DpId - not in PIn"TEST:_Users.UserId"
...
6/opcuasrv, OpcUaSGroupHotlinkWFA in Funktion hotLinkCallBack, Ungültige DpMessage-Antwort empfangen
...
39, Connection lost, DP: TEST:_DpGroup00015_Public.Dps:_online.._value, MAN: (SYS: 1 Device -num 6 CONN:


Any ideas or suggestions what the problem could be?


I configured the DP-Groups OPCUAAlarm and OPCUARead with the same DP(E)-Filter: *.in.*.*:_online.._value


these are my config entries

[opcuasrv]
enableAnonymous=1
tcpServerPort=4841

Best regards
Aleks

Can you please check which alias is defined for the dp groups you are using.
The alias must be set not the name for the dp group.

I am using the standard groups OPCUARead. The default Alias is OPCUARead.
I just noticed, that for OPCUAAlarm the alias is missing.

Now I can start the driver.

Is the Alias also needed for each Datapoint?

Thank you very much.
