Abstract

Claims (24)

1. A method of communicating a message between an automotive device of an automotive control area network and a non-automotive, industrial device of a non-automotive, fieldbus network, the method comprising:

receiving a message of a source format from one of the automotive device of the automotive control area network and the non-automotive, industrial device of the non-automotive, fieldbus network;

translating the message of the source format to a common language format;

processing the message of a common language format via a set of stored, configurable rules;

translating the processed message of a common language format to a destination message format;

delivering the message in the appropriate destination format to one of the automotive device of the automotive control area network and the non-automotive, industrial device of the non-automotive, fieldbus network.

2. The method of claim 1 , wherein the message includes more than one message.

3. The method of claim 1 , wherein the automotive device of the automotive control area network includes multiple automotive devices of the automotive control area network.

4. The method of claim 1 , wherein the non-automotive, industrial device of the non-automotive, fieldbus network includes multiple non-automotive, industrial devices of the non-automotive, fieldbus network.

5. The method of claim 1 , wherein receiving a message of a source format is performed using an electronic transceiver, the electronic transceiver transmits the message to a microprocessor, and the microprocessor performs the translating and processing steps.

6. The method of claim 1 , wherein the set of stored, configurable rules include instructions to at least one of send, discard, and modify the message.

7. The method of claim 1 , further including a CAN-to-fieldbus converter and a protocol handler unique to a specific fieldbus protocol of the non-automotive, fieldbus network integrated into the CAN-to-fieldbus converter.

8. The method of claim 7 , wherein the CAN-to-fieldbus converter includes a transceiver as a permanent component of the converter, and the transceiver performs as an electronic voltage and impedance interface.

9. The method of claim 8 , wherein the transceiver is a modular component incorporated into the converter during manufacture of the converter.

10. The method of claim 8 , further including a microprocessor, and power to the transceiver is turned on and off via a signal from the microprocessor.

11. The method of claim 1 , wherein a microprocessor performs the translating steps using one or more tables.

12. The method of claim 11 , further including the step of supplying the one or more tables with the automotive control area network.

13. The method of claim 11 , further including the step of supplying the one or more tables with the non-automotive, fieldbus network.

14. The method of claim 1 , further including the step of supplying the set of stored, configurable rules with the automotive control area network.

15. The method of claim 1 , further including the step of supplying the set of stored, configurable rules with the non-automotive, fieldbus network.

16. The method of claim 1 , wherein the receiving, translating, processing, and delivering steps are performed using a self-contained, on-board, CAN-to-fieldbus converter.

17. The method of claim 16 , further including a waterproof enclosure containing the self-contained, on-board, CAN-to-fieldbus converter, and the enclosure is impervious to heat and vibration from an automotive environment.

18. The method of claim 16 , wherein the self-contained, on-board, CAN-to-fieldbus converter includes a separate protocol handler and microprocessor, and the protocol handler is specific to the non-automotive, fieldbus network.

19. The method of claim 18 , wherein the protocol handler is removable from the self-contained, on-board, CAN-to-fieldbus converter and is replaceable with another protocol handler specific to a different non-automotive, fieldbus network, and the method further includes removing the protocol handler from the self-contained, on-board, CAN-to-fieldbus converter, and replacing the protocol handler with another protocol handler specific to a different non-automotive, fieldbus network.
