A network topology for communication within and between food service equipment items generally comprises one or more food service equipment items, each having a controller and at least one functional subsystem configured as a slave to the controller, and a master interface and a bus slave interface associated with each controller. Each master interface is adapted for electrical communication over an intra-equipment communication channel with a slave interface associated with the functional subsystem. Each bus slave interface is adapted for communication,...

1. A network topology for communication within and between food service equipment items, said topology comprising:a food service equipment item, said equipment item comprising a controller and at least one functional subsystem configured as a slave to said controller;a master interface associated with said controller, said master interface being adapted for electrical communication over an intra-equipment communication channel with a slave interface associated with said functional subsystem; anda bus slave interface associated with said controller for communication, external to said food service equipment item, over an inter-equipment communication channel, said bus slave interface being substantially electrically identical to said slave interface. 2. The network topology as recited in claim 1, wherein said food service item comprises a plurality of functional subsystems. 3. The network topology as recited in claim 2, wherein said functional subsystems comprise at least one subsystem selected from the group consisting of:an ice link central processing unit;a vacuum pump controller; andan ice diverter. 4. A network topology for communication within and between food service equipment items, said topology comprising:a plurality of food service equipment items, each said equipment item comprising a controller and at least one functional subsystem configured as a slave to said controller;a master interface associated with each said controller, each said master interface being adapted for electrical communication within the respective equipment item over an intra-equipment communication channel with a slave interface associated with each said functional subsystem; anda bus slave interface associated with each said controller for communication, between said food service equipment items, over an inter-equipment communication channel, each said bus slave interface being substantially electrically identical to each said slave interface. 5. The network topology as recited in claim 4, wherein the inter-equipment communication channel comprises a hardwired bus. 6. The network topology as recited in claim 4, wherein the inter-equipment communication channel comprises a radio frequency (“RF”) link. 7. The network topology as recited in claim 6, wherein the inter-equipment communication channel comprises a hybrid interconnection, said hybrid interconnection comprising at least an RF link component and a hardwired bus component. 8. The network topology as recited in claim 7, said network topology further comprising an inter-equipment communication channel, said inter-equipment communication channel being in communication with the master interface of one and only one of said food service equipment items and the said slave interface of at least one other of said food service equipment items. 9. The network topology as recited in claim 8, wherein said inter-equipment communication channel is in communication with a master interface associated with an ice dispenser equipment item and with a slave interface associated with a vacuum pneumatic ice conveyance system. 10. The network topology as recited in claim 8, wherein said inter-equipment communication channel is in communication with a plurality of slave interfaces, each said slave interface being associated with a distinct food service equipment item other than said food service equipment item associated with said master interface. 11. The network topology as recited in claim 8, wherein said inter-equipment communication channel is in communication with a master interface associated with a vacuum pneumatic ice conveyance system and with a plurality of slave interfaces associated with food service equipment items selected from the group consisting of:a vacuum pneumatic ice conveyance system;an ice dispenser equipment item; anda beverage dispenser equipment item. 12. The network topology as recited in claim 9, wherein said inter-equipment communication channel is in communication wi th a master interface associated with a beverage dispenser equipment item and with a slave interface associated with a source of pressurized gas. 13. The network topology as recited in claim 12, wherein said pressurized gas comprises carbon dioxide. 14. A network topology for communication within and between food service equipment items, said topology comprising:a plurality of food service equipment items, each said equipment item comprising a controller and at least one functional subsystem configured as a slave to said controller;a master interface associated with a first said controller, said master interface being adapted for electrical communication within the equipment item over an intra-equipment communication channel with a slave interface associated with each said functional subsystem configured as a slave to said first controller;a bus slave interface associated with said first controller for communication, external to the food service equipment item, over an inter-equipment communication channel, said bus slave interface being substantially electrically identical to each said slave interface; anda logical switch associated with said first controller, said logical switch being adapted to selectively configure said first controller as a master device or a slave device with respect to the inter-equipment communication channel. 15. The network topology as recited in claim 14, wherein said first controller is adapted for communication through said bus slave interface with an external network interface when said first controller is configured through said logical switch as a master device. 16. The network topology as recited in claim 15, wherein said network interface comprises an embedded web server. 17. The network topology as recited in claim 15, wherein said network interface comprises a router. 18. The network topology as recited in claim 15, wherein said network interface comprises a bridge. 19. The network topology as recited in claim 15, wherein said network interface comprises a MODEM. 20. The network topology as recited in claim 15, wherein said network interface comprises a network interface. 21. The network topology as recited in claim 15, wherein said network interface is adapted to interface said food service equipment items, through said first controller, to a wide area network. 22. The network topology as recited in claim 21, wherein said wide area network comprises the Internet. 23. The network topology as recited in claim 22, wherein said network interface is adapted to collect and store information related to the operation of said food service equipment items. 24. The network topology as recited in claim 23, wherein said network interface is adapted to periodically communicate said information related to the operation of said food service equipment items to a remote location. 25. The network topology as recited in claim 24, wherein said network interface further comprises a network controller. 26. The network topology as recited in claim 24, wherein said network interface further comprises a personal computer. 27. The network topology as recited in claim 26, wherein said network interface further comprises a network controller.
