Abstract:
1. A method of binding a control system device to a controller, comprising: receiving, by a first master controller, a first device discovery beacon from a first control system device; evaluating the beacon for inclusion of a first device type flag; determining the beacon includes the first device type flag; evaluating a value of the first device type flag; determining the value indicates the first control system device comprises a server configured to bind to multiple master controllers; loading, by the first master controller, an instance of a device module associated with the first control system device responsive to determining the value indicates the first control system device comprises the server configured to bind to multiple master controllers; receiving, by the first master controller, a second device discovery beacon from a second control system device; evaluating the second device discovery beacon for inclusion of a second device type flag; determining the second device discovery beacon does not include the second device type flag; adding, by the first master controller, a designation of the second control system device to an unbound dynamic physical device list maintained by the first master controller; detecting, by the first mater controller, a binding notification on a multicast address indicating the second control system device has been bound to another master controller different from the first master controller; and removing by the first master controller, the designation of the second control system device from the unbound dynamic physical device list.
