Abstract

A device for controlling an operating state of at least one component of a production plant, including an energy control unit for providing a state change signal for changing the operating state of the at least one component from a first operating state to a second operating state, wherein the device includes a monitoring unit which is designed to receive the state change signal of the energy control unit, and to provide the state change signal of the energy control unit for changing the first operating state to the second operating state, and to modify the state change signal of the energy control unit for providing the second operating state, and to block the state change signal of the energy control unit for preventing a change of state into the second operating state.

First claim

The invention claimed is:

1. A device for controlling an operating state of a plurality of components 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 of the plurality of components 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.

2. The device as claimed in claim 1 , wherein the monitoring device is designed to provide a third operating state alternative to the second operating state if the monitoring device blocks the first state change signal of the energy control device.

3. The device as claimed in claim 1 , wherein the monitoring device is designed to provide the energy control device with a current operating state of the first component for synchronizing the energy control device with the at least one component.

4. The device as claimed in claim 1 , wherein the monitoring device is designed to block the first state change signal of the energy control device if the changing of the first operating state into the second operating state is predetermined as an unallowed and/or as an impossible state change.

5. The device as claimed in claim 1 , wherein the monitoring device is designed to provide the first state change signal of the energy control device and to block the further state change signal of the higher-level control device if the first state change signal of the energy control device has a predetermined, higher priority than the further state change signal of the higher-level control device, and to provide the further state change signal of the higher-level control device and to block the first state change signal of the energy control device if the further state change signal of the higher-level control device has the predetermined higher priority.

6. The device as claimed in claim 1 , wherein the monitoring device is designed to deactivate the energy control device for blocking the first state change signal and/or to activate the energy control device for providing the state change signal.

7. The device as claimed in claim 6 , wherein the energy control device, after activating, is designed to read out the current operating state of the first component.

8. The device as claimed in claim 1 , wherein the monitoring device is designed to monitor a state change time of the state change from the first operating state into the second operating state and, if the state change time exceeds a predetermined threshold value, to specify the associated state change signal as an impossible and/or unauthorized state change signal.

9. The device as claimed in claim 1 , wherein the monitoring device is designed to provide at least one intermediate operating state for modifying the first state change signal of the energy control device, if the second operating state can only be reached via the at least one intermediate operating state from the first operating state.

10. The device as claimed in claim 1 , wherein the monitoring device is designed to modify the first state change signal for performing a test cycle.

11. 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.

12. 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,
