Hi,

I wondered if there is a way to get the **ObjectType** definition of an OPC UA NodeId.  
So far I can browse my opcua server using the ignition functions available, the returned objects ( [PyOPCTagEx](http://files.inductiveautomation.com/sdk/javadoc/ignition80/8.0.12/com/inductiveautomation/ignition/common/script/builtin/AbstractOPCUtilities.PyOPCTag.html), [OPCBrowseElement](http://files.inductiveautomation.com/sdk/javadoc/ignition80/8.0.12/com/inductiveautomation/ignition/common/opc/OPCBrowseElement.html)) do not contain this information.

I cannot find a way to get to the attribute for an ObjectType.

I am using a Siemens S7-1500, Ignition 8.1.25

I can see in UAExpert the ObjectType definition for each Object.

Ignition's OPC UA browsing only requests Variables, Objects, and Methods. You won't be able to see ObjectTypes.

Thanks, Kevin. Will be nice to have this added in the future. This gives us the full capacity to auto-generate the plant using custom udt in the PLC since I can browse any node in my PLC.
