CAN i use parallel computing to send CAN messages

so i have a function called moveRob to read USB Joystick data then send it via can message but when i try to call it like this from my appdesigner GUI it doesn't work.

batch(@moveRob ,0,{app.canCh_rob});

so my question is how can i do this using parallel computing. because when i run the Batch it doesn't recognize the CAN message i sent and i think it needs to intialize it from the beggining so what i want is the batch use the same can message as the main program not to intialize new one
