Abstract
A device operatively couples a tractor ABS controller with TABS controllers in units towed by the tractor. A PLC interface circuit of the device communicates messages received from a PLC network of the towed units to a CAN network of the tractor via a CAN interface circuit. The device may also rebroadcast messages received from the PLC network back onto the PLC network, and may also wirelessly broadcast messages received from the PLC network back onto a wireless network. The device receives messages from the towed units at a message rate, determines a quantity of towed units from the message rate, and communicates the determined quantity of towed units on the CAN network of the tractor. The device receives messages indicating towed unit identification (ID) information, determines a quantity of towed units from the towed unit ID information, and communicates the determined quantity of towed units on the CAN network.
