Hello, I have OPC tags declared and would like to access all their attributes via a reference tag in a UDT. Is this possible?  
The tags follow a good naming structure.  
I have tried but it seems that the only thing that is referenced is the value.

here is an example of the origin tag

{  
"valueSource": "opc",  
"opcItemPath": PATH,  
"tagType": "AtomicTag",  
"opcServer": "LAH\_SRV\_KNAR",  
"name": "M9\_L\_FREKVENSOMFORMARE",  
"historyEnabled": true,  
"historyProvider": "MSSQL",  
"tooltip": "Larm frekvensomsformare",  
"dataType": "Boolean",  
"Larm\_mode": "WhileTrue",  
"Larm\_priority": "High",  
"Larm\_enabled": true,  
"Larm\_notes": "Knäred RV M9 Larm frekvensomsformare",  
"Larm\_timeOnDelaySeconds": 0.0,  
"Larm\_ackNotesReqd": true,  
"Larm\_atgard": "Ingen åtgärdstext konfigurerad",  
"objecType": "DigitalAlarm"  
},

Correct, because that is the only thing that is expected to change after configuration. However you configure these reference tags is the time to copy other attributes, and copying later changes will have to be scripted.

Reference tags only reference the value.

Properties, security, alarms, and other configuration are not referenced.
