I would like to establish reuse of TestStand LabVIEW Steps between an embedded controller PXI chassis and an extended PXI chassis (that uses a MXI 3). How can I best manage and programably establish instrument or device identification to the VI's without hardcoding the different device id's into the test steps. Is there a feature of MAX that would allow a common naming convention or can I programmably get each card's identification and use global variables? I am lost as to what is the best strategy in dealing with varying instrument identification and wanting to reuse VI's.
