Thank you very much, that's what i need. 

Hello, everyone:

I got 64 buttons on my front panel. I'd like to make these buttons interlock, only one button is allowed to be activated all at the once.

Currently my code's efficient is not good as what i expected. The picture below is the block diagram of my code. Anyone has a good way to do this?

Attached is my VI.

 XNET can do periodic frames well; I've done this with the PCI card. The database of frames contains the intervals to send them. As I recall loading the database was all that was needed. Setting the frame values changed what was being periodically sent.

Tks, it seems that couldn't work with the "NI USB-8473"

I don't understand.  Are you writing CAN or reading it?  Are you using NI-CAN or NI-XNET?  What is your hardware, is it NI based even?  Post your code.

That being said I've never had any problem reading or writing CAN frames at different rates in any API.

Oh and if you are new to LabVIEW here is some free training:

My hardware is NI-USB8473. And what I wanna do is to periodic send CAN frames, but they have difference time interval.

Example, Frame A should be sent by each 50ms and Frame B should be sent by each 200ms.  

Thanks very much for your links, do u know how to post a picture, BTW?

Here is my current block diagram

Hello, team:

Recently, I face a problem to send 2 CAN frames with different interval.

i.e.       Frame          Interval

            FrameA         50ms

            FrameB         200ms

The thing is that interval time is the longer one always. I have less knowledge of Labview so far, I don't know which structure could be used in my condition.

Any help would be appreciated. Thanks you.
