Unable to change variable value to True about python-opcua HOT 12 OPEN

some server doesn't allow setting the timestamp. you need to set it via DataValue.

datavalue = ua.DataValue(ua.Variant(True, ua.VariantType.Boolean))
node.set_value(datavalue)

from python-opcua.

Same issue with your code:

            node = client.get_node("ns=3; i=16847616")
            data_value = ua.DataValue(ua.Variant(True, ua.VariantType.Boolean))
            node.set_value(data_value)

Error: "The server does not support writing the combination of value, status and timestamps provided."(BadWriteNotSupported)

from python-opcua.

Try this:

node.set_attribute(ua.AttributeIds.Value, ua.DataValue(True))

from python-opcua.

same error. sorry

from python-opcua.

Are you sure you can write that value? Dod you try it via ua expert?

from python-opcua.

it works using uaexpert.

why is there a blank after ; in the nodeid?

Do you mean « , »in the description of nodeid on UA expert ? I don’t know

from python-opcua.

datavalue = ua.DataValue(ua.Variant(True, ua.VariantType.Boolean))
datavalue.SouceTimestamp = None
datavalaue.ServerTimestamp = None

Try to remove status or add one of the timestamp. That is what the server says is the issue but does not tell us what it wants
