Abstract

An industrial control system includes a central controller having a memory containing programmable data including operating programs for operating the controller, control program for controlling an industrial process, and configuration data configuring values used by the operating program and control program. The central controller is designed to control multiple devices also having memory holding programmable data including operating programs and configuration data. A program is executable by the central controller that causes the central controller to identify memories distributed through the industrial control system having programmable data and collect the programmable data from the memories. Accordingly, the collected programmable data may be used to substantially recreate operation of the industrial control system in a second industrial control system having another central controller substantially identical to the industrial controller and multiple devices connected to the central controller.

1. In an industrial control system providing a central controller having a memory containing programmable data including operating programs for operating the controller, control program for controlling an industrial process, and configuration data configuring values used by the central controller, the central controller controlling multiple devices also having memory holding programmable data including configuration data, the improvement comprising:

a program executable by the central controller to;

identify memories distributed through the industrial control system having programmable data; and

collect the programmable data from the memories; and

wherein the collected programmable data may substantially recreate operation of the industrial control system in a second industrial control system having another central controller substantially identical to the industrial controller and multiple devices connected to the central controller.

2. The industrial control system of claim 1 further comprising a device list accessed by the central controller to identify the memories.

3. The industrial control system of claim 1 wherein the program is executable by the another central controller to substantially clone the industrial control system by distributing the collected programmable data across the memories of the multiple devices of the second industrial control system.

4. The industrial control system of claim 1 wherein the program is executable by the central controller to automatically distribute at least a portion of the collected programmable data to a given device replacing at least one of the multiple devices.

5. A computer readable storage medium having stored thereon a computer program comprising instructions that, when executed by an industrial controller arranged in an industrial control system, causes the industrial controller to:

request identity information from each of a plurality of modules in the industrial control system;

compare the identity information of each of the modules to stored identity information; and

if the identity information of a module in the industrial control system does not match the stored identity information, automatically send a reconfiguration package from the industrial controller to the module to reconfigure the module to match the stored identity information.

6. The program of claim 5 wherein the identity information includes a current firmware version and the stored identity information includes a desired firmware version and wherein, if the current firmware version does not match the desired firmware version, the reconfiguration package includes the desired firmware.

7. The program of claim 6 wherein the industrial controller is further caused to:

determine whether each module has been designated for exact firmware version matching; and

send the desired firmware version only if the module is designated for exact firmware version matching.

8. The program of claim 5 wherein the identity information includes a module type and wherein the industrial controller is further caused to:

determine whether the module type of each of the modules is listed in the stored identity information as approved for identity matching; and

send the reconfiguration package to the module only if the module type listed in the stored identity information as approved for identity matching.

9. The program of claim 5 wherein the identity information includes a module brand and wherein the industrial controller is further caused to:

determine whether the module brand of each of the modules is listed in the stored identity information as approved for identity matching; and

send the reconfiguration package to the module only if the module brand is listed in the stored identity information as approved for identity matching.

10. The program of claim 5 further comprising a memory unit engaged with the industrial controller and wherein the identity information is stored on the memory unit and accessible by the industrial controller.

11. The program of claim 10 wherein the memory unit includes a removable non-volatile memory unit.

12. The program of claim 10 wherein the memory unit includes a removable compact flash unit.

13. The program of claim 5 wherein the reconfiguration package is automatically sent from the industrial controller to the module during operation of the industrial control system.

14. The program of claim 5 wherein industrial controller is further configured to request and compare the identity information from each of the modules to the stored identity information automatically upon at least one of a system power on event, a industrial controller power on event, a module replacement event, a module power on event, a removable memory module engagement event, a memory failure event, an expiration of a time limit, a communication loss event, and a user initiation event.

15. A method of automatically maintaining firmware versions in an industrial control system having an industrial controller and a plurality of modules, the method comprising the steps of:

18. The method of claim 15 further comprising the step of configuring the industrial controller to automatically determine whether each of the plurality of modules has be pre-designated for firmware matching and communicate the desired firmware version to a module only if the current firmware version of the module is not the desired firmware version the and module has been pre-designated for firmware matching.

19. The method of claim 15 further comprising the step of configuring the industrial controller to periodically query each of the plurality of modules to determine whether the current firmware version is the desired firmware version.
