Hey ho,

first things first - please read #1475

To your problem:
Word isn't an inbuilt type of OPC UA.
Here is the source of the VarianTypes from this (deprecated) library:

python-opcua/opcua/ua/uatypes.py

Line 624 in 96a8ea6

class VariantType(Enum):

You need your nodeset file (I guess from SIOME or PLCOpen?), import it, load the datatype definition and then you can create and interact with a node.
