J1939 Add-on Feedback

Daniel,

Ok, something "new". How would one go about modifying the core device such that message could be sent out by pressing a "send" button? I know the workspace tool can send raw CAN frames. But, what I want that same on-demand sending ability with a custom panel that is wired to the input channels for the CAN frame signals?

Hi, Danel, I want to add a channel on this customer device to get the timestamp information. Do you have any instructions?

I have changed customer device and add a channel at outgoing channel but I cannot add one channel at incoming. When I tried to get the timestamp, I can not get the signal. I added some code here at the vi (Source\Engine\SubVIs\Main Read Processed Incoming Messages.vi)

What is the correct method to add a channel?

Thank you very much!

Hey,

That will not work unless you explicitly create channels for the timestamp in the system definition for each incoming frame AND make sure that the timestamp channel for a given frame is immedaitely after that frame (the order of the channels has to match the order of the dbl array you are updating).  If you do that, it should work.

I hope that helps!

Thanks!

Dan

Hi Daniel,

thanks for sharing the addon for the community.

Currently we are trying to evaluate this with Veristand/Labview 2016 

on a cRIO 9064(!!LINUX!!)

Could you provide an update that supports the linux operating systems

and a latest NI Software ?

Best Regards

Juergen

Any ideas why I might be seeing 74 occurrences of 65535.01?   Also wondering why pressing refresh DTC's does not get it to show the currently active DTC?  Common mistakes that might cause this behavior?

I think these 74 occurances might be occuring during a power cycle of the only ECU on the bus, so the "cluster" (not sure if that is the right term) would only have one CAN controller (the pxi chassis) in babbling idiot mode.

Win7 (7601) SP1

VeriStand 2016 (2016.0.0.72)

XNET 16.0.0

PXI Chassis1085

PXI Controller 8135

PXI 8512 CAN Cards

Before updating from J1939 2.0.0 to 4.0.0, my message ID was normal, but then after the upgrade, the last 8 bit of the message ID changed to 0 0.

Is there a built version for VeriStand 2017, is there any updates?

Is there a way to disable a simulated device at run-time?  I.e. Prevent it from doing any communication for example when I swap in a real device for that particular simulated device.

Hi, All

I have a problem about export parameter.

What's the meaning of it?

Veristand 2018 SP1 & LabVIEW 2018 SP1.

Thanks~

When you change the source address or name of a simulated device, it unsets the "include destination address" setting.  See the fix in the attached image for "J1939 Addon System Explorer.lvlib:Simulated Device Page.vi".
