Hey,

I am a little confused by what you are trying to do.  Are you looking at how to determine which signal to set?  From the images, it looks like you are trying to send one message with multiple signals inside.  You are trying to set up logic that says which lights should be on.  To do this, you would add the frame and signals from the database to the custom device's outgoing event triggered section.  This makes it so you should be able to turn on and off the lights manually.  If you wanted some logic, you could use calculated channels, a model, or an automated test to determine or set these logic levels.  If you need help on these, I would refer to the online VeriStand help.  Please let me know if I am understanding the question.

I hope this helps!

Please let me know what you have tried and what you are expecting.  Also, please read the Getting Started Document and internal help.  It talks about how to command DM1 from the workspace object, from the diagnostic channels, and from LabVIEW.  There is even an example posted on the J1939 add-on page on how to do this using a RT sequence (J1939 Stimulus Profile Example.zip).

Hey Jarm,

No one ever sent me anything to compare.  Therefore, I have no new information or ideas.

Daniel,

I've been trying to deploy my project with my latest database, but I was getting an error saying there was an object that didn't exist.  I isolated the specific message that was causing the error, but the message did exist in the database, and nothing has changed in the database that should cause this error.  I tried refreshing the database, deleting and adding back the database, deleting the custom device and adding it back, deleting everything then adding it all back, nothing works.  In the end I went into the PXI Chassis and tried to find the databases that were being deployed to the Chassis every time I deploy the project, thinking maybe these were bad for some reason and weren't being updated with deployment.  However, the only place I could find them was in the ni-rt/system/xnetdb and dbcache folders.  I noticed the files in the xnetdb folder were old, while the files in the dbcache folder were new.  I went ahead and deleted the files in the xnetdb folder to see if new files would be added once I tried to deploy.  This caused a new error, a bad reference error.  This error remains even after I copied the files from the dbcache folder to the xnetdb folder.  I can get the file I deleted back if I need to, but I'm confused on why I now have a bad reference error now.

PS, the error does not come up when I remove the custom device and add the database to an NI-XNET CAN object.

Hey Tyler,

Please send me your database through a private message, I will test it on my system.  Also, I have an update coming that should handle databases better.

Thanks!

Is it possible to have it built for VeriStand 2010? I need to send a 39 byte message and this add-on seems to be the best tool for that. I tried opening the source code in Labview 2013 then save it back to Labview 2010 but Labview crashed. Thanks
