NI-CAN simultaneous Read/Write at different sample rates

[Matisson]

Hello everybody,

I am a beginner in LabVIEW and here is my problem :
I would like to read a CAN message every 10ms, and then write a CAN message (with the data received from the CAN Read.vi) every 20ms.
Do I have to build 2 different While loops to do it ? If it's right, how can I share the data between the 2 loops, without losing any value ? With queues ???

I have already made a VI that read and write at the same sample rate (i.e. 100 Hz => 10 ms). But when I put 50 Hz in the Task Init Start function for the CAN Write function, I'm losing values (I have only 1 While loop).

If you have any exemple of functions doing nearly the same, I am interessed in.

Thanks in advance !
