Architecture for modular energy system

A modular energy system for use in a surgical environment, the system comprising:

• a plurality of modules, wherein each of the plurality of modules comprises one of an initial module, a terminal module, and a functional module,
• wherein each of the functional modules and the terminal module comprises:
• a module control circuit;
• and
• a local data bus comprising:
• a communication switch;
• a first switch data path configured to permit data communication between the communication switch and the module control circuit;
• a second switch data path in data communication with the communication switch;
• and
• a third switch data path in data communication with the communication switch;
• and
• wherein the initial module comprises a physical layer transceiver (PHY) in data communication with an initial module control circuit;
• a termination unit in data communication with the third data path of the terminal module;
• and
• an internal data bus comprising a serial array of the local data busses of the plurality of functional modules and the terminal module,
• wherein a third switch data path of a functional module N is in data communication with a second switch data path of a functional module N+1,
• wherein a second switch data path of the terminal module is in data communication with a third switch data path of a preceding functional module, and
• wherein the internal data bus further comprises the physical layer transceiver (PHY) of the initial module in data communication with a second switch data path of a succeeding functional module.
