Abstract

A system and method are provided for controlling an embedded device. The method comprises: establishing a control code repository; establishing a plurality of objects corresponding to a plurality of control routines; establishing a range of selectable data values associated with each data object; accessing the repository through a plurality of mediums selected from the group including an embedded device front panel, simple network management protocol (SNMP), hypertext transport protocol (HTTP), a serial port, and a parallel port; and, using the control codes to communicate with an embedded device as follows: selecting data values; and, issuing commands to the embedded device in response to the data values.

Claims

1. A method for controlling an embedded device, the method comprising:

establishing a control code repository;

accessing the repository through a first plurality of mediums; and

,

using the control codes to communicate with an embedded device.

2. The method of claim 1 wherein accessing the repository through a first plurality of mediums comprises accessing the repository through mediums selected from the group including an embedded device front panel, simple network management protocol (SNMP), hypertext transport protocol (HTTP), a serial port, and a parallel port.

3. The method of claim 2 wherein establishing a control code repository includes establishing a second plurality of control routines;

and,

wherein using the control codes to communicate with an embedded device includes controlling a second plurality of embedded device functions through the second plurality of control routines.

4. The method of claim 3 further comprising:

establishing a second plurality of objects corresponding to the second plurality of control routines;

establishing a range of selectable data values associated with each object;

wherein using the control codes to communicate with an embedded device includes;

selecting data values; and

,

issuing commands to the embedded device in response to the data values.

5. The method of claim 4 wherein accessing the repository through a first plurality of mediums includes:

querying the repository from a medium;

identifying an object as the subject of the query; and

,

the method further comprising;

receiving an acknowledgement in response to the query.

6. The method of claim 5 wherein receiving an acknowledgement in response to the query includes:

identifying an object as the subject of the response; and

,

identifying a data value associated with the identified object.

7. The method of claim 6 wherein accessing the repository through a first plurality of mediums includes proposing the data value associated with the identified object;

and,

wherein receiving an acknowledgement in response to the query includes acknowledging the use of the proposed data value.

8. The method of claim 7 wherein establishing a control code repository includes establishing a data entity associated with each object;

wherein using the control codes to communicate with an embedded device includes;

receiving the data values proposed by the mediums; and

,

writing the proposed data values in the corresponding object data entities.

9. The method of claim 8 further comprising:

at the repository, establishing an asynchronous notification associated with a third object;

establishing a notification trigger associated with third object data entity;

in response to the occurrence of the notification trigger, receiving the notification at the first plurality of mediums;

identifying the third object as the subject of the notification; and

,

receiving a third data value associated with the third object in the notification.

10. The method of claim 8 further comprising:

establishing a first plurality of communication protocols corresponding to the first plurality of mediums;

wherein establishing a control code repository includes establishing a repository calling interface with object and data value fields for communications with corresponding data entities in the repository; and

,

wherein accessing the repository through a first plurality of mediums includes each medium converting its corresponding communication protocol into appropriate object and data values for communications with corresponding data entities, and calling the repository interface.

11. A method for controlling an embedded device, the method comprising:

establishing a control code repository;

establishing a second plurality of objects corresponding to a second plurality of control routines;

establishing a range of selectable data values associated with each data object;

accessing the repository through a first plurality of mediums selected from the group including an embedded device front panel, simple network management protocol (SNMP), hypertext transport protocol (HTTP), a serial port, and a parallel port; and

,

using the control codes to communicate with an embedded device as follows;

selecting data values; and

,

issuing commands to the embedded device in response to the data values.

12. A system for controlling an embedded device, system comprising:

a control code repository;

a first plurality of mediums accessing the repository; and

,

an embedded device responsive to control code communications from the repository.

13. The system of claim 12 wherein the first plurality of mediums are selected from the group including an embedded device front panel, simple network management protocol (SNMP), hypertext transport protocol (HTTP), a serial port, and a parallel port.

14. The system of claim 13 wherein the repository includes a second plurality of control routines;

and,

wherein the embedded device includes a second plurality of embedded device functions controlled through the second plurality of control routines.

15. The system of claim 14 wherein the repository further comprises:

a second plurality of objects corresponding to the second plurality of control routines;

a second plurality of data selectors with selectable data values, corresponding to each object; and

,

wherein the repository selects data values, and issues commands to the embedded device in response to the data values.

16. The system of claim 15 wherein a medium from the first plurality of mediums queries the repository, identifies an object as the subject of the query, and receives an acknowledgement from the repository, in response to the query.

17. The system of claim 16 wherein the medium receives an acknowledgement from the repository identifying an object as the subject of the response and including a data value associated with the identified object.

18. The system of claim 17 wherein the medium proposes the data value associated with the identified object and receives an acknowledgement from the repository acknowledging the use of the proposed data value.

19. The system of claim 18 wherein the repository establishes a data entity associated with each object, receives the data values proposed by the mediums, and writes the proposed data values in the corresponding object data entities.

20. The system of claim 17 wherein the repository establishes an asynchronous notification associated with a third object, establishes a notification trigger associated with a third object data entity, and in response to the occurrence of the notification trigger, sends the notification to the first plurality of mediums;

and,

wherein the mediums identify the third object as the subject of the notification and receive a third data value associated with the third object in the notification.

21. The system of claim 17 wherein the repository establishes a repository calling interface including object and data value fields for communications with corresponding data entities in the repository;

and,

wherein each of the first plurality of mediums communicates using a corresponding communication protocol, wherein each medium converts its corresponding communication protocol into appropriate object and data value fields for communications with corresponding data entities, and calls the repository interface.
