Systems and methods for implementing CAN communication for building automation systems are disclosed. An exemplary system may comprise at least one sending device linked to a plurality of receiving devices over a CAN automation network. A control frame may be broadcast over the CAN automation network by the at least one sending device, the control frame encapsulated into a CAN extended data frame. An acceptance filter may be provided at each of the plurality of receiving devices, each of the plurality of receiving devices reading the control frame from the CAN extended data frame and determining if the receiving device is a target device based on the control frame. Device communication may also be implemented as methods for dynamic address assignment and firmware download.
