Using Kvaser leaf CAN inverter with Labview application

[rivlin]

Hi

I am working with two motor controllers in the CAN network, so I downloaded an application (attached) from KVASER's site which is suitable for the inverter I have.
I should get speed data from one controller and update the second controller so that there is a uniform speed.
I entered parameters, send a request and get a response from one controller. I need to send the answer to the second controller, but I can not isolate the DATA from the output string.
Also, There seems to be a lock in one of the VI's  because I am unable to add probes to some internal VI's.
Also, how can I update the second controller every 10 milliseconds?

Thanks

The "output string" is created by the kvCanMsgDisplayBox function - from the outputs given by kvCanRead!

Why don't you use the "Message data" output of that CanRead function?

Check the VI properties: is debugging en-/disabled in those VIs?

You may try to send a CAN message each 10ms using a parallel loop.

When the Kvaser API allows you can setup a periodic CAN message, which is sent by the CAN controller each 10ms and only update the message data as needed…
