Synchronizing PXIe-6361 AI with XNET-CAN

[Zweimercedes]

Hello everyone,

I have a PXI chassis (PXIe-1073) with two modules inside: one PXI 6361 and one PXI 8512 module. And would like to synchronize one analog input of the PXI 6361 with the XNET card (which receives CAN messages). Unfortunately I didn't find any examples for my case. Has anyone already experience in this?

Thanks for your help!

Can you explain what do you mean by synchronize ? Start receiving CAN Messages once the AI signal reaches a predefined value as a sort of trigger....?

Hello kartiknattar,

I would like to measure the position from two different devices (sensor and reference). The sensor communicates via CAN and the reference is connected to the input of the DAQ module. I want to synchronize the data, so I can get the deviation of the sensor signal.

Hi Zweimercedes,

Have you found any example on this? Lately I have met the same request from my customer. If you have any clue or material, would you please share with me?

Thanks in advance!

Hello Zhaoyong,

Currently I am not working on this project. But I found this example from NI which comes very near to my case: Synchronize XNET CAN with X Series DAQ

I also got one code from a collegue, which is working but it's written in CVI. I can tell from the code that it's all about the initialization of the DAQ and XNET.

Kind regards,

Thanks Zweimercedes!

This is really helpful for me to understand the synchronization mechanism. Actually my customer is seeking solution based on .NET language like C# and I haven't found any existing example. Do you happen to have some clue?

Thanks again!

Hello Zhaoyong,

I am not very familiar with C#, but I could offer a code example in C. I uploaded the c- and header-files to the attachments. You can view the c- and h-files with a standard code viewer. Wish you good luck for your project!

Kind regards,
