OPC UA Toolkit can't send arguments to read a data

I have a PLC with OPC UA interface that can reply a data with input arguments (like a function)

How to send these arguments in the read function ?

I have a PLC with OPC UA interface that generates custom data format, for some important data like alarms and setpoint updates, in a cluster of various scalar datas [one int, one string, one timestamp, ...).

Asking the data format of an URL return the right value, but as it is a cluster, the read data can't access the value and return an format error. If unknown format are hard to encode in Labview, it should at least return the raw value (like a flat to string) that I can try to convert properly in a cluster, as I know its composition.
