Method for saving energy in e.g. switch of industrial automation network in production plant, during planning and designing phases, involves switching network node to energy saving state, if no network apparatuses are attached at terminals

摘要

The method involves detecting whether operational network apparatuses are attached (S1) at network terminals, where the network node is connected with the network apparatuses of a network via the network terminals. A network node is switched (S2) from an operating state into an energy saving state, if no operational network apparatuses are attached at the network terminals over a time period, where the network node receives and stores information about a structure of the network for detecting whether the operational network apparatuses are attached at the network terminals. Independent claims are also included for the following: (1) a network node (2) a computer program product for saving energy in a network node.
