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, external to the food service equipment item, over an inter-equipment communication channel. Each bus slave interface is substantially electrically identical to each slave interface.
