Abstract

Exemplary embodiments are directed to a system and method for integrating field devices in an automation system having a plurality of field devices connectable via at least one bus system. A respective field device is connected to the bus system of the automation system, and is automatically addressed by a superordinate controller using a predefined default address. The device addressed using the default address then registers in the system with its device address, and a fixed address which is provided from a multiplicity of unassigned addresses from an address memory is automatically allocated to the device registered in the system. An individually assigned identification (TAG) provided from the predetermined configuration of the automation system is allocated to the allocated fixed address, and, after the automatically allocated fixed address has been transmitted to the field device, the field device is changed to a suitable state for communication with the superordinate controller.

Claims

1. A method for automatically integrating field devices in an automation system having a plurality of field devices connectable via at least one bus system, the field devices being incorporated in the automation system via the bus system according to a predetermined configuration stored in memory of the automation system and executed by a processor of the automation system, the method comprising:

connecting a respective field device to the bus system of the automation system;

automatically addressing the respective field device connected to the system by a superordinate controller using a predefined default address by means of an automatically running first routine;

registering the default address of the addressed device in the system using its device address;

allocating automatically a fixed address selected from a plurality of unassigned addresses in an address memory is automatically allocated to the device registered in the system by means of a second automatically running routine;

allocating an individually assigned identification (TAG) provided from the predetermined configuration of the automation system to the allocated fixed address; and

after the automatically allocated fixed address has been transmitted to the respective field device, changing the field device to a suitable state for communication with the superordinate controller.

2. The method according to claim 1, comprising:

adopting the assigned fixed address into the project data relating to the installation of the distributed system, the project data describing the hardware provided in the system.

3. The method according to claim 1, comprising:

detecting a fixed address which has already been automatically allocated to the respective field device from the address area using a test routine, wherein the address which has already been allocated is retained by the respective field device.

4. The method according to claim 1, comprising:

changing the previously automatically allocated fixed address to a previously unassigned bus address from the address area using a change routine.

5. The method according to claim 1, wherein a special address in the address area is reserved for the respective field device on the basis of a predefined function in the automation system.

6. The method according to claim 1, wherein the automatic address allocation is started with the aid of a graphical user interface.

7. The method according to claim 1, wherein the configuration steps of allocating the identification (TAG) and/or assigning it to a planned functionality are executed by a start-up tool.

8. The method according to claim 7, comprising:

automatically assigning an identification (TAG) which is already stored in the respective field device and corresponds to the project data to the pre-planned functionality using the start-up tool.

9. The method according to claim 1, wherein the automation system communicates using the field bus protocols PROFIBUS and/or Foundation field bus.

10. An automation system, comprising:

at least one bus system;

a plurality of field devices connectable via the at least one bus system; and

a superodinate controller configured with program code, wherein the controller includes;

means for automatically addressing a respective field device connected to the system using a predefined default address;

means for registering the default address of the addressed device in the system using its device address;

means for allocating automatically a fixed address selected from a plurality of unassigned addresses in an address memory is automatically allocated to the device registered in the system;

means for allocating an individually assigned identification (TAG) provided from the predetermined configuration of the automation system to the allocated fixed address; and

means for changing the field device to a suitable state after the automatically allocated fixed address has been transmitted to the respective field device.

11. The system according to claim 10, comprising:

memory for storing the assigned fixed address into the project data relating to the installation of the distributed system, wherein the project data describes the hardware provided in the system.

12. The system according to claim 10, wherein the controller comprises:

means for detecting a fixed address which has already been automatically allocated to the respective field device from the address area using a test routine, wherein the address which has already been allocated is retained by the respective field device.

13. The system according to claim 10, wherein the controller comprises:

means for changing the previously automatically allocated fixed address to a previously unassigned bus address from the address area using a change routine.

14. The system according to claim 10, wherein the controller reserves a special address in the address area for the respective field device on the basis of a predefined function in the automation system.

15. The system according to claim 10, comprising:

a graphical user interface for starting automatic address allocation.

16. The system according to claim 10, comprising:

a start-up tool for allocating the identification (TAG) and/or assigning it to a planned functionality.

17. The system according to claim 16, wherein the start-up tool automatically assigns an identification (TAG) which is already stored in the respective field device and corresponds to the project data to the pre-planned.

18. The system according to claim 10, wherein the automation system communicates using the field bus protocols PROFIBUS and/or Foundation field bus.

19. A processing apparatus of an automation system having a plurality of field devices connectable via at least one bus system, comprising:

memory for storing a predetermined configuration of the field devices;

means for automatically addressing a respective field device connected to the system using a predefined default address;

means for registering the default address of the addressed device in the system using its device address;

means for allocating automatically a fixed address selected from a plurality of unassigned addresses in an address memory is automatically allocated to the device registered in the system;

means for allocating an individually assigned identification (TAG) provided from the predetermined configuration of the automation system to the allocated fixed address; and

means for changing the field device to a suitable state after the automatically allocated fixed address has been transmitted to the respective field device.
