Abstract

A cooling system includes a compressor rack, a controller, a gateway, and a system master. The compressor rack includes a plurality of compressors. A controller is dedicated to each compressor and includes a memory storing configuration data for the compressor. A gateway is in communication with each controller and allows the system master to command the controller to send the configuration data to the system master, whereby the system master stores a copy of the configuration data for each compressor.
