DriverTag how to store a dataset?

Module Development
1

Ignition 7.9.10
I try to store a Dataset in a DriverTag but DataType have no DatasetType ?

2

You can’t, Dataset is an Ignition datatype, not an OPC UA datatype.

3

Ok, I see. I will try to use Array for each column.

I hoped it was possible because in the designer, we can choose Dataset for OPC tag datatype, but not in the Source Data Type. I suppose it’s just for data cast purpose (Array => Dataset with 1 comumn ?)

4

I’m not sure if that dropdown is even aware of the type of tag it’s being used on. I don’t know what implicit casts are done, if any.

5

can we store Array Value in DriverTag ?

6

No that won’t work either. It might allow you to set an array value without error but the OPC UA node wouldn’t have the proper ArrayDimension and ValueRank attributes set.

7

too bad, to avoid too much code refactoring I will need to serialize the result in a string tag…:cry:
