Accessing custom device FIFO array element by name


Some of my custom devices have a large number if I/Os. Because the FIFOs are arrays, my custom device RT driver VI has been referencing them by indexing the arrays. Is there a recommended method to reference FIFO I/Os by name, and preferably the same name as the channel names that are created by the initialization VI? Referencing array elements by index can get very confusing and not very flexible if I need to add or remove custom device I/Os. Thanks.

You could use an enum diagram constant to wire to the index terminal of index array. Make the item name correspond to the element name.
