Image Number 6 for United States Patent #7984136.
Methods, systems, and computer program products for automatically determining locations of interconnected processing modules are disclosed. Physical identifiers are determined for each of a plurality of processing modules connected to each other in a linear topology. Communications are iteratively disabled with each of the processing modules. Discover messages are sent to active, reachable processing modules and responses are received from the active processing modules that receive the discover messages. Based on the number of responses, the location of each processing module is determined.
