Update value of variables

[omidfathi]

Hi, how can I update the value of variables on the server side?

[AndreasHeine]

please look into the examples folder!

yes, I looked before.
I use:

await server.write_attribute_value(tags[987].nodeid, ua.DataValue(1.25))

and
print(tags[987].nodeid) --> NodeId(Identifier=520, NamespaceIndex=2, NodeIdType=<NodeIdType.FourByte: 1>)

but I get this warning :

Write refused: Variant: Variant(Value=1.25, VariantType=<VariantType.Double: 11>, Dimensions=None, is_array=False) with type VariantType.Double does not have expected type: VariantType.Float

The datatype must match. Try this:
await server.write_attribute_value(tags[987].nodeid, ua.DataValue(ua.Float(1.25)))

The datatype must match. Try this: await server.write_attribute_value(tags[987].nodeid, ua.DataValue(ua.Float(1.25)))

Thank you, it's working now.
