DEVICE FOR OPERATING DECENTRALIZED FUNCTIONAL UNITS ARRANGED IN AN INDUSTRIAL INSTALLATION

摘要

The invention discloses a device (E) and a method for operating decentralized functional units (DFE) arranged in an industrial installation, comprising: a) a superordinate control system (30) which interchanges information with the decentralized functional units (DFE) using data messages (DT), b) a data transport network (TN) having a number of network access points (2 to 16), wherein the superordinate control system (30) is coupled to the data transport network (TN) via at least one network access point (2, 4); c) communication units (18 to 28) which are connected to a network access point (6 to 16) and provide the decentralized functional units with access to the data transport network (TN), characterized by d) an energy transport network to which the decentralized functional units are connected and which supplies the decentralized functional units with electrical energy; and e) a number of intelligent energy stores which are connected to the energy transport network and consume energy and/or output energy in accordance with the superordinate control system and/or at least one of the other energy stores.
