Device for operating decentralized functional units arranged in an industrial installation

A device for operating decentralized functional units disposed in an industrial installation, the device comprising:

• a super ordinate control system for interchanging information with the decentralized functional units by means of data telegrams;
• a data transport network with a number of network access points, said super ordinate control system coupled via at least one of said network access points to said data transport network;
• communication units connected in each case to one of said network access points and providing the decentralized functional units with access to said data transport network;
• an energy transport network to which the decentralized functional units are connected and supplying the decentralized functional units with electrical energy;
• and
• a number of intelligent energy stores connected to said energy transport network, said intelligent energy stores receiving energy and/or output the energy in coordination with said super ordinate control system and/or with at least one of the other said intelligent energy stores.

A method for operating decentralized functional units disposed in an industrial installation, which further comprises:

• interchanging information between a super ordinate control system and the decentralized functional units by means of data telegrams;
• coupling the super ordinate control system to a data transport network via at least one network access point of the data transport network having a plurality of network access points;
• providing communication units, being connected in each case to one of the network access points, and provide the decentralized functional units with access to the data transport network;
• providing an energy transport network to which the decentralized functional units are connected and supplying the decentralized functional units with electrical energy;
• and
• providing a number of intelligent energy stores connected to the energy transport network, the intelligent energy stores receive energy and/or output the energy in coordination with the super ordinate control system and/or with at least one of the other intelligent energy stores.
