I have the AIM ARINC429 ACE in my NI PXIe 8881 chassis and want to utilize a loopback LabVIEW VI for this card however I cannot find any and trying to utilize the provided C loopback code is causing a lot of issues.
Is anyone if there is a loopback VI that would work for this card?

Have you tried the VI from their official website?

Thank you for the response!! The only VI I was able to find in code base was a VI that transmitted values from a transmit channel and then had a delay then read them from a receive channel.
I am looking for a VI that reads in a stream of data and immediately writes each incoming data word out to a transmit channel while still reading. (Essentially 1 in 1 out).
I have found a VI called CreateSession(RxTx- Loop) that initializes Rx and Tx channels and then called Rx Data Loop Assign and Config Labels Rx VIs. Could this be used/ does anyone have insight on what I would use this in conjunction with to create the type of looping I am looking for?

If you also use VeriStand, consider using this LabVIEW-built custom device:
