> According to Part 4, 5.10.4.2 of the OPC UA specification, the status code
> returned by the write operation is used if the server does not support

> Are there already values on the server for the range you are trying to
> write? Usually, servers fail to update a range if there is no previous

> If you were just trying to write the entire array, use writeAttribute()
