Access PLC Datatype Metadata via Ignition OPC

We’d like to collect a comment that was added to a PLC tag (beckhoff structured text) and view it in ignition. It’s possible to do this via UaGateway using the ‘Description’ Attribute, of the type Opc.Ua.Localized.

What we are trying to achieve is to use this as a message associated with the variable for the purposes of alarming and event handling. It would be more efficient for us to transfer this as metadata than to have to create a separate data type.

Unfortunately there is no access to attributes other than Value right now.

This may change in the future, via the addition of something like a system.opcua.readAttribute scripting function, but there isn’t a timeline I could give you on that.
