Q: I am having trouble figuring out which CAN bus I am communicating with (A or B). What happens if I send command to CU_B? Is there a way to tell which is which?
A: Unless you have some really old software (do you know when the machine was purchased?), then CU_B is a slave of CU_A. If you send commands to CU_B they should be ignored. The ports are inside the UI (User Interface) box are labeled as CAN_A and CAN_B.
