Communication with a CAN-Bus Shield

Hi there!

I have a big problem....
I would like to send the following bytes from the Arduino Uno to the CAN-Bus Shield, if I receive '01,00':
'00,00,00,01,00,00,00,00,00,00,00,01'. How can I do that in a very graceful way?
I would be very happy about a helpful answer.

Kind regards
Cankar
