Abstract

Example methods and apparatus to transmit device description files to a host are disclosed. A disclosed example method includes communicatively coupling a field device to the host to provision the field device within a process control system, receiving an indication that the host does not include a version of a device description file that corresponds to a version of the field device, accessing the device description file from a memory of the field device, and transmitting the device description file from the field device to the host.

Claims

1. A method to transmit device description files to a host, the method comprising:

communicatively coupling a field device to the host to provision the field device within a process control system;

receiving an indication that the host does not include a version of a device description file that corresponds to a version of the field device;

accessing the device description file from a memory of the field device; and

transmitting the device description file from the field device to the host.

2. A method as defined in claim 1, further comprising transmitting a query from the field device to the host causing the host to determine if the host includes the device description file associated with the field device.

3. A method as defined in claim 2, wherein the query further causes the host to determine if the host includes the version of the device description file that corresponds to the version of the field device.

4. A method as defined in claim 1, wherein the device description file is transmitted to the host in response to receiving a request from the host for the device description file.

5. A method as defined in claim 1, wherein the device description file is stored in a compressed format within the memory.

6. A method as defined in claim 1, further comprising:

receiving an indication of a type of the host; and

selecting the device description file from the memory based on the type of the host.

7. A method as defined in claim 6, wherein the type of the host includes at least one of a model number of a process control handheld device, a type of a wireless device, a type of a processor, a type of a server type, or a type of a controller.

8. A method as defined in claim 1, wherein the device description file is configured based on activated functions of the field device.

9. A method as defined in claim 1, wherein the host refrains from accessing the device description file from a manufacturer of the field device after receiving the device description file from the field device.

10. A method as defined in claim 1, wherein the device description file enables the host to display process data generated by the field device.

11. An apparatus to transmit device description files to a host, the apparatus comprising:

a device type identifier to identify a host communicatively coupled to a field device within a process control system;

a file processor to receive an indication that the host does not have a device description file that corresponds to a version of the field device;

a file retriever to access the device description file from a memory of the field device; and

a transmitter to transmit the device description file from the field device to the host.

12. An apparatus as defined in claim 11, wherein the field device is provisioned within the process control system before the device type identifier identifies the host.

13. An apparatus as defined in claim 11, wherein the file processor is to transmit a query to the host to determine if the host includes the device description file.

14. An apparatus as defined in claim 13, wherein the query is to determine if the host includes a version of the device description file that corresponds to the version of the field device.

15. An apparatus as defined in claim 11, wherein the transmitter transmits the device description file to the host in response to the file processor receiving a request from the host for the device description file.

16. An apparatus as defined in claim 11, wherein:

the device type identifier receives an indication of a type of the host; and

the file retriever selects the device description file based on the type of the host.

17. An apparatus as defined in claim 11, wherein the file processor is to configure the device description file based on activated functions of the field device.

18. A tangible article of manufacture storing machine-readable instructions that, when executed, cause a machine to at least:

provision a field device within a process control system;

identify a host communicatively coupled to the field device;

receive an indication that the host does not include a device description file that corresponds to a version of the field device;

access the device description file from a memory of the field device; and

transmit the device description file from the field device to the host.

19. A tangible article of manufacture as defined in claim 18, wherein the machine-readable instructions, when executed, cause the machine to transmit a query to the host to determine if the host includes the device description file associated with the field device.

20. A tangible article of manufacture as defined in claim 18, wherein the machine-readable instructions, when executed, cause the machine to transmit a query to the host to determine if the host includes a version of the device description file that corresponds to the version of the field device.
