Description

Trying to read values from the opc-ua server from the IQunet sensor no data is received because of a NOT FOUND exception that appears reading all node ids. You can access these node ids using other clients, like FreeOpcUa.

After debugging the problem, the issue is located in this logical check.

This condition:

readValues.get(counter).getStatusCode() != StatusCode.GOOD

must be

! readValues.get(counter).getStatusCode().equals(StatusCode.GOOD)

I am uploading a PR which fixes the issue.
