1. A method for saving energy at a network node in an automation network, the method comprising:

  • receiving energy saving command data for switching at least one network device of network devices connected to network ports at the network node to an energy saving state in which the at least one network device consumes less energy than in an operating state;

    forwarding the energy saving command data to the at least one network device;

    evaluating the energy saving command data by the network node; and

    switching at least a portion of the network node to an energy saving state to save energy at the network node, the network node at least one of receiving and outputting one of no data and a reduced volume of data to the at least one network device when the at least one network node is in the energy saving state;

    wherein the at least one portion of the network node to be switched to the energy saving sate is determined based on network ports associated with the at least one network device in the energy saving state.
