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

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

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 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, for synchronizing the energy control device with the at least one component with a current operating state of the at least one component.

4 . The device as claimed in claim 1 , wherein the monitoring device is designed to block the state change signal of the energy control device 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 device has a higher-level control device which is designed to provide a further state change signal and the monitoring device is designed to communicate with the higher-level control device.

6 . The device as claimed in claim 5 , wherein the monitoring device is designed to provide the state change signal of the energy control device and to block the further state change signal of the higher-level control device if the 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 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.

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

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

9 . 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.

10 . The device as claimed in claim 1 , wherein the monitoring device is designed to provide at least one intermediate operating state for modifying the 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.

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

12 . A production system having a production plant having at least one component and having a device as claimed in claim 1 .

13 . A method for controlling an operating state of at least one component of a production plant in which a state change signal is provided by an energy control device for changing the operating state of the at least one component from a first operating state into a second operating state, characterized in that the state change signal of the energy control device is received by a monitoring device, and by the monitoring device either the state change signal of the energy control device is provided for changing the first operating state into the second operating state or the state change signal of the energy control device is modified for providing the second operating state or the state change signal of the energy control device is blocked for preventing the second operating state.
