Ignition 8.1 OPC UA Server and dataset tag types

Ignition
1

I’m using the Ignition OPC UA Server to expose some tags to another software (OPC UA client app): from my tests it seems it is not possible to expose query tags with a Dataset data type (I cannot see them when browsing from the other app). Could you confirm?

Thanks, regards

(Current Ignition version: 8.1.3 (b2021030309))

Confirmed, not possible. There’s not really an equivalent OPC UA datatype.

Ok, thanks Kevin. However as I can see, it’s ok to expose arrays - no cons I think.

Yes, arrays should be fine, though if you need to write back to them you can only write the entire array value and not just elements or subranges by using the indexRange parameter of the OPC UA Write service.
