AIT ARINC 429 Add-On Feedback

Hi,

I don't have an answer to your mapping problem but I can help you about the Graph : you need to modify the history length in the setup of the graph.

Regards

I have no idea why the mappings dialog would not show the inputs. I just tried again and saw no problems on my computer. That is very strange.

Perhaps close and reopen NI VeriStand?

Can you post your database and system definition file for me to look at?

This graph allows a much longer history length: https://decibel.ni.com/content/docs/DOC-32299

It was the database our macro to create the xml database was messing up incoming ARINC....my bad.  Thanks for the help.

Stephen,

I am getting the following when I try to undeploy from the target, see attached.  It happened several times and now I cannot connect over the web browser or max to the target.  Can you help me with this?  Thanks!

[StephenB]

yes this is a problem with the AIT 4.6 driver. See the known issues list on the custom device page for a solution

Stephen,

we were checking some things on the ARINC Transmission, would you think it is possible to achieve a more even label spread?

e.g. what it seems like is that if you have 4 labels define like this:

label 1 25ms

label 2 50ms

label 3 100ms

label 4 200ms

in this condition you get labels transmitted in bursts at 25ms with a resulting super burst at the lcm

t0 lbl 1+2+3+4

t0+25 lbl1

t0+50 lbl1+2

t0+75 lbl1

t0+100 lbl1+2+3

t0+125 lbl1

t0+150 lbl1+2

t0+175 lbl1

t0+200 lbl1+2+3+4

keeping the same scheduling rates, but shifting label 2 interleaving by 25ms would make the data stream more even.

Any thought on how to achieve that?

Hi Stripes,

You should be able to achieve this by using the initial delay field in the configuration file:

Hi,

I think that I have found something strange.

I have a project with around 10 RX and 200 TX in one mode and for other test everything as to be turned to RX channels.

Problem is that when I deploy my full RX configuration I actually don't have input loop duration and output loop duration moving. If I add one TX channel in the configuration it starts to work again.

Question : Only RX configuration sould be working or do I have to always have at least one TX channel ?

PS : I am working with a modified addon v2.0 on LV 2014 and VeriStand 2014. Modification only impact on system explorer not RT driver.

Hi Benjamin,

Thanks for reporting this issue. Do you receive data over those RX channels? Or do they also stay zero, like the loop duration channels.

[BenjaminM]

I just test it and the answer is no there is no data on these channels.

The test was performed with loopback exemple modified to delete TX channels.

A AIT429 USB card, link to an other computer, is used to send test label. We monitored this output with an oscilloscope so that we are sure that we really have the expected label.

Thanks for the quick answer
