You will need to override IoManager.writeValue in the MyBigIoManager.

When doing so, i assume it’s the UaVariable arg2 that i need to modify. This is null however. Any pointers to how i continue?

The DataItem:s are not implemented with UaVariable objects, but inside the MyBigNodeManager.

Should i interpret that as that there is no relatively easy way to alter the server in such a way that it can update values sent from the client live? Or maybe you would be so kind to elaborate how one would go around and modify the IoManager.writeValue in MyBigIoManager?

It should be pretty straight forward, if you compare against readValue(). E.g.:
protected boolean writeValue(ServiceContext serviceContext,
NodeId nodeId, UaVariable node, NumericRange indexRange,
DataValue dataValue) throws StatusException {
DataItem dataItem = getDataItem(nodeId);
if (dataItem == null)
throw new StatusException(StatusCodes.Bad_NodeIdInvalid);
dataItem.setValue(dataValue.getValue().doubleValue(),
dataValue.getStatusCode());
return true;
}
Just make sure that simulation is also disabled (in MyBigNodeManager.simulate()), since it is writing the values normally all the time.
