Various aspects of the instant disclosure are directed towards a method for communicating time-based data in a power line communication system. In accordance with one or more example embodiments, firmware is downloaded to a multitude of endpoints over power distribution lines carrying alternating current (AC) power. Endpoint devices targeted for changes to stored firmware are grouped and the firmware is delivered in chunks to each group. As devices receive a particular chunk of firmware, the device advances to a next stage and provides information indicative of this stage, based upon which subsequent chunks of firmware are communicated. This occurs (e.g., on a daily cycle) until the endpoint has received all firmware for an update, after which the endpoint(s) are re-started using the firmware. Accordingly, such updates can be carried out in a cyclic and verifiable manner.

Power line network apparatus, system and method

Aspects of the present disclosure are directed toward a system that includes a plurality of endpoint devices. Each endpoint device can be configured and arranged to monitor a plurality of communication channels carried over power distribution lines for data communications. The endpoint can detect setup communications that contain an endpoint identifier (ID) matching the endpoint. The endpoint then stores or assigns the organization ID (obtained from the detected communications) to itself. The endpoint configures itself to respond to subsequent operational communications based upon the organization ID. A command center is configured and arranged to transmit setup communications to endpoint devices. The setup communications can include one or more endpoint identifiers and the organization ID. The command center can also transmit operational communications to the plurality endpoint devices, the operational communications including the organization ID.
