Abstract: A work machine using a distributed controller network that provides for redundant data buses is described herein. The work machine uses a controller area network that provides for redundant data buses for tier 1 controllers, or controllers that are determined to have a higher degree of importance when compared to other controllers. The controller area network uses redundancy to decrease the probability of a communication failure between tier 1 controllers and tier 2 controllers. The tier 1 controllers have communication access to two data buses between other tier 1 controllers and tier 2 controllers. Thus, if a data bus used by a tier 1 controller cannot be used by the controller, the tier 1 controller can use the other, redundant data bus to maintain communication.
