Abstract:
1. A communication system for direct communication between powered elements, the communication system comprising: a controller hub that injects a first message via a first modulated communication signal onto a branch circuit using a hub-side power line communication (PLC) coupler; an element-side power line communication (PLC) coupler associated with a powered element in a set of powered elements that detects the first message and sends an interrupt to a mini-controller in the powered element; the mini-controller: the powered element performs a command identified in the first message; the powered element sends a second message to the mini-controller; the mini-controller injects the second message via a second modulated communication signal onto the at least one branch circuit using the element-side PLC coupler; the hub-side PLC coupler associated with the controller hub detects the second message and sends an interrupt to the controller hut; the controller hob: wherein the second message is a request for an increase in power by the powered element and wherein receiving the request for the increase in power further comprises:
