TMS320F28069M: How to use PIL model by using EXTERNAL MODE as CAN instead of serial

Hello,

I am using PIL in simulink. Created Plant model running in software and controller model running as PIL block in hardware. Here I am using external mode as SERIAL WITH COM6 means plant and controller with serial communication. But, now I want to communicate plant and controller with CAN communication. so which kind of settings to be configured for that. which are the instructions to be used on command prompt to configure PIL ON CAN as like here

PIL ON SERIAL PORT:

setpref('mathwaork_embedded_ide_link_pil_preferences','compORT', COM6)

Thank you.
