Read Multiple Variable Values from object node

[hleon32]

We are able to get variable node with individual tags but we cannot read multiple tag values using one GET call. Also, we are having issues with Datatype as our variable node datatype is Long and not able to cast to BuiltInType. How can we read multiple tag values using one GET request?

Unfortunately, it is only possible to read a single value per request. There is no batch request implemented. Concerning your DataType issue, instead, you should provide more details because Long is neither a BuiltIn DataType nor a Standard DataType as defined in part 3. Anyway, as a general rule you should always reduce any DataType usage in a BuiltIn DataType adoption.

The response of the method, await session.ReadValuesAsync(nodeIds) returns (DataValueCollection, IList<ServiceResult>).
Since we are providing list of nodeIds, we are expecting to have which DataValue object (in DataValueCollection response) belongs to which nodeId.
As far as I understand, it's not possible at the moment :(
