Abstract

Improved script generation and usage for handheld field maintenance tools is provided. In one aspect, the handheld field maintenance tool actually generates scripts for later playback. Preferably script generation and/or playback or features are provided to field maintenance technicians. Additionally, scripts can be played on the handheld field maintenance tool without modification to the tool itself.

Claims

1. A computer-implemented method of generating a script for a handheld field maintenance tool, the method comprising:

observing at least one of input and output activity on the tool; and

recording at least one frame on the tool relative to the observed activity.

2. The method of claim 1, wherein the at least one of input and output activity includes a tool input.

3. The method of claim 1, wherein the at least one of input and output activity includes a tool output.

4. The method of claim 1, wherein the at least one of input and output activity includes a process communication input.

5. The method of claim 4, wherein the process communication input is in accordance with HART®

protocol.

6. The method of claim 4, wherein the process communication input is in accordance with the FOUNDATION™

Fieldbus protocol.

7. The method of claim 1, wherein the at least one of input and output activity includes a process communication output.

8. The method of claim 7, wherein the process communication output is in accordance with HART®

protocol.

9. The method of claim 7, wherein the tool is adapted for use with a process control system and wherein the process communication output is in accordance with the FOUNDATION™

Fieldbus protocol.

10. The method of claim 1 wherein the frame is indicative of a problem in the process control system.

11. The method of claim 1, and further comprising automatically recording frames beginning when the tool is energized.

12. The method of claim 11, wherein substantially all input and output activity on the tool is recorded in the frames.

13. The method of claim 12, and further comprising receiving an indication that a sequence of frames is indicative of a problem, and storing the indication.

14. The method of claim 1, wherein the at least one of input and output activity is related to information from a field device in a process control system.

15. A computer-implemented method of playing back a script, the method comprising:

conveying the script to memory within a handheld field maintenance tool;

causing the tool to enter a script playback mode;

playing the script on the tool as a stand-alone playback device.

16. A handheld field maintenance tool comprising:

a display;

memory to store at least one script; and

a processor coupled to the display and the memory and adapted to execute the script in a stand-alone playback mode to display script execution.

17. The tool of claim 16, further comprising:

first and second media access units coupled to the processor, wherein the first media access unit is adapted to couple to a process communication loop in accordance with a first process communication protocol, and wherein the second media access unit is adapted to coupled to a process communication loop in accordance with a second process communication protocol different from the first process communication protocol.
