Do We Have Examples to Perform Scheduled and Asynchronous Messages by ARINC 429 Queries Simultaneously?

Updated Mar 4, 2026

Hardware

  • Ballard ARINC-429

Issue Details

I want to transmit both periodic (scheduled) messages and aperiodic (asynchronous/dynamic/triggered) messages simultaneously on the same ARINC 429 bus.
 
  • How do I create a scheduled message using the BTI XML Editor?
  • How do I configure asynchronous messages as described in the Omnibus User Manual? Specifically, how do I configure them in the BTI XML Editor and how they are transmitted/how they behave compared to periodic (scheduled) messages?

Solution

To send a triggered (asynchronous) message while periodic (scheduled) messages are active, use the LabVIEW example: Example 06 – Transmit Scheduled and Dynamic Messages. Path: C:\Program Files\NI\LVAddons\ballardinstr32\1.6.0.3\examples\Astronics Ballard Technology\BTI429Lib\Example 06 - Transmit Scheduled and Dynamic Messages

You must install the Astronics Ballard Avionics Driver to access the example and the BTI Editor. Use the BTI XML Editor to define ARINC 429 channels, labels, and transmission mode (scheduled vs asynchronous/triggered). Then, in LabVIEW, open the BTI device, load the project/XML, start the schedule, and issue a trigger to send the asynchronous message.
