Node red OPC UA server not updating

[dinesh]

Hi,

I am setting up OPC UA server(0.2.236) in node red. Using some online code I was able to set it up.

However, when Using Prosys OPC UA Client for testing, i'm able to to see the variable but the problem it is not updating. I have included my flow. Please advise

thank you

Thank you

Easy fix: variable name must contain namespace index. Add namespace = 1 to payload.
New version gives warning if parameter is missing.

Example:
msg = { payload : { "messageType" : "Variable", "variableName": "Tipo Real", "variableValue": msg.payload }};
msg.payload.namespace = 1;

Hi,

It works now. I actually had to update the node red opcua(2.236->2.261(latest)).

Once updated, the flow provided by you started working.

Thank you
