Issue Details

I'm using the NI-XNET property nodes to extract a select list of signals from my database to use in my program.

However, when trying to run the program XNET Create returns the following error:

Error -1074384541
NI-XNET:  (Hex 0xBFF63163) You used an empty name for an XNET database object (database, cluster, ECU, frame, or signal). Empty name is not supported. Solution: Refer to NI-XNET help for IO names to review the required syntax for the name, and change your code to use that syntax.

Why is this happening and how can I fix this? 


This error is due to the XNET Create expecting an array of the datatype XNET signals, but when extracting signal names, you get them in the String datatype.
