HI Mahadev,

If you need quicker responses or have an urgent issue please contact your local National Instruments office ni.com/contact and select the option to request technical support.

The NI Example Finder found in LabVIEW under Help menu » Find Examples has an example written for towards this purpose. You can build off of this VI give you the ability to change when you want to read of write to the card. Remember that the card honors the timing associated with the database (if you are using one). I recommend taking a read through the NI CAN Hardware and Software Manual so that you can understand the different modes that are avaliable in the NI-CAN driver. NI Developer Zone Tutorial The NI-CAN Channel API is also a good starting point if you are not using a USB-CAN device. Are you?

thanks for the reply.

I used that VI but whenever i used to run that VI , after some time it is poping up an error called write queue overflow. What does this error mean and how can i overcome this error.

Please provide me with ur inputs they are very valuable to me.

Thanks

Mahadev
