Abstract

Systems, methods, and computer program products for easily altering redundancy management data values associated with redundancy management logic that is executed by redundant data processing systems. The redundancy management data values are altered on a computer device remote from the system that includes the redundant data processing systems.

Claims

1. A system comprising:

a computer configured to execute a ground-based software tool; and

a device comprising;

at least two data processing systems, the at least two data processing systems perform redundant operations based on control logic; and

memory for storing data values,

wherein the ground-based software tool includes a component configured to allow a user to change at least one of the stored data values used by the control logic.

2. The system of claim 1, wherein the data values include weight values.

3. The system of claim 1, wherein the data values include time limit values.

4. The system of claim 1, wherein the data values include switching threshold values.

5. The system of claim 1, wherein the data values include weight values, time limit values, and switching threshold values.

6. The system of claim 1, wherein the device is an aircraft.

7. The system of claim 6, wherein the at least two redundant data processing systems include communication management units.

8. The system of claim 1, wherein the device is a communication system.

9. The system of claim 1, wherein the computer stores data values on a removeable storage device, the device further includes a data loader for receiving the removeable storage device and storing the data values on the storage device into the memory.

10. A method comprising:

altering at least one redundancy management data value associated with redundancy management logic at a computer;

saving the altered data value on a removeable storage device; and

sending the at least one altered redundancy management data value from the removeable storage device to memory included in an apparatus;

wherein the apparatus includes at least two data processing systems, wherein the at least two data processing systems perform redundant operations and execute redundancy management based on the one or more redundancy management data values stored in the memory.

11. The method of claim 10, wherein the redundancy management data values include weight values.

12. The method of claim 10, wherein the redundancy management data values include time limit values.

13. The method of claim 10, wherein the redundancy management data values include switching threshold values.

14. The method of claim 10, wherein a the redundancy management data values include weight values, time limit values, and switching threshold values.

15. The method of claim 10, wherein the apparatus is an aircraft.

16. The method of claim 15, wherein the at least two redundant data processing systems include communication management units.

17. The method of claim 10, wherein the apparatus is a communication system.

18. The method of claim 10, further comprising:

receiving the removeable storage device at a data loader of the apparatus; and

storing the data values on the storage device into the memory.

19. A computer program product for performing a method comprising:

altering at least one redundancy management data value associated with redundancy management logic for a system including at least two data processing systems that perform redundant operations; and

saving the altered data value on a removeable storage device.

20. The computer program product of claim 19, wherein at least one redundancy management data value includes weight values, time limit values, and switching threshold values.
