If the dynamic physical device comprises a server that is configured to bind to multiple master controllers, the dynamic physical device may include a device Type Flag and set the value of the device Type Flag to indicate the dynamic physical device comprises a server. On detection of the beacon, a master controller evaluates the device Type Flag if it is present in the device discovery beacon. If the device Type Flag is present and indicates the dynamic physical device comprise a server which may bind to multiple master controllers, the master controller may automatically load a device Module for the dynamic physical device and commence communications with the dynamic physical device with no manual intervention. ## Claims ### Claim 1 A method, comprising: receiving, by a first master controller, a first device discovery beacon from a first control system device;
