Write analogue channel to CAN bus

I have a cDAQ with a number of analogue and digital I/O modules installed. What I would like to do is take some of the analogue inputs and transmit them onto a CAN bus using the NI 9862 module. I know the basics of how to read the analogue data but I'm not sure how to get this onto the CAN bus, does anyone have a sugested starting point?

Thanks,

Richard
