Selective industrial power-over-network configuration and operation

An industrial process environment uses selective power-over-network (PoN) techniques to facilitate configuration, operation, communication, and other operations for the industrial nodes in the environment. The network may be an Ethernet network, and the environment may selectively deliver power-over-Ethernet as well as command, configuration, or other data over the network connection. The environment may perform the techniques over other types of networks or combinations of networks in addition to or instead of Ethernet networks.
