Device for coordinated controlling of an operating state of a production plant and production system and method

A production system having a production plant having a plurality of components and having a device for controlling an operating state of the at least one component of a production plant, comprising:

• an energy control device for controlling operating states of the plurality of components of the production plant, wherein the energy control device determines an energy efficient operating state for each respective component of the plurality of components when use of the respective component of the plurality of components is not expected, and wherein the energy control device provides a first state change signal for changing the operating state of a first component from a first operating state into a second operating state, wherein at least one of the first operating state and the second operating state are at least one of:
• an off state, an on state, and a stand-by state;
• a higher-level control device designed to provide a further state change signal for changing the operating state of the first component, wherein the higher-level control device determines a command for optimized production flow;
• and
• a monitoring device for monitoring the controlling of the plurality of components of the production plants by the energy control device and the higher-level control device, wherein the monitoring device is designed to receive the first state change signal of the energy control device and the further state change signal of the higher-level control device and to:
• provide the first state change signal of the energy control device for changing the first operating state into the second operating state,
• modify the first state change signal of the energy control device for providing the second operating state, and
• block the first state change signal of the energy control device for preventing a state change into the second operating state,
• wherein the monitoring device performs one of providing, modifying, and blocking based on a comparison of the first state change signal of the energy control device with the further state change signal.

A method for controlling an operating state of a plurality of components of a production plant, comprising:

• providing, by an energy control device, a state change signal for changing the operating state of at least one component of the plurality of components from a first operating state into a second operating state, wherein the energy control device determines an energy efficient operating state for each respective component of the plurality of components when use of the respective component of the plurality of components is not expected,
• providing, by a higher-level control device designed to provide a further state change signal for changing the operating state of the first component, a command for optimized production flow, and
• receiving, by a monitoring device, the state change signal of the energy control device and the further state change of the higher-level control device, wherein the monitoring device either provides the state change signal of the energy control device for changing the first operating state into the second operating state, modifies the state change signal of the energy control device for providing the second operating state, or blocks the state change signal of the energy control device for preventing the second operating state, based on a comparison of the first state change signal of the energy control device with the further state change signal,
• wherein the providing and receiving steps are also conducted for a second state change signal for changing the operation state of a second component of the plurality of components.
