Could a guru have a look to that LabVIEW user post. Thanks.
@Reynald It’s a Tango kernel question rather than a LabVIEW binding one.
I think I located the problem. It’s in the binding in fact. When a proxy to a tango device is instantiated, the binding tries to retrieve each attribute alias for the tango db - an action which itself requires the TANGO_HOST to be defined.
