BadNodeIdUnknown error - by: samirhaj

Hello,

I am running an application under .Net framework with using Opclab sdk. When I start my application to read/write values of different types (boolean, integer, float, etc) , it crashes with the following error;

The status of the OPC-UA attribute data is not Good. The actual status is 'BadNodeIdUnknown'. The client method called was 'WriteMultiple'.

I am reading and writing values from/to OpcUa server like the following;

rollingCounterGds = Convert.ToInt16(_client.Read("opc.tcp://127.0.0.1:62333/DrillView", "ns=2;s=GdsCounter").Value);
_client.WriteValue("opc.tcp://127.0.0.1:62333/DrillView", "ns=2;s=DhsCounter", dhsToGdsDb.DhsCounter);

Could you please advise on how to resolve this?

Best regards.
