Abstract
A method for communicating includes transmitting a command message from a lead vehicle to remote vehicles in a vehicle consist. Reply messages are transmitted from the remote vehicles to the lead vehicle. The reply messages include statuses of the remote vehicles that transmitted the reply messages. The status of a first remote vehicle but not of the second remote vehicle is received at the lead vehicle and the status of a second remote vehicle is received at the first remote vehicle. The status of the second remote vehicle is stored at the first remote vehicle a retry message is transmitted from the lead vehicle to the remote vehicles. The retry message is received at the first remote vehicle and a repeat message is transmitted from the first remote vehicle to the lead vehicle that includes the status of the second remote vehicle.
