The method includes receiving a master golden record for a device of a plurality of devices in the industrial automation system. The master golden record includes one or more parameter values for the device for a mode of the industrial automation system. The method also includes identifying an active mode for the industrial automation system. The method also includes responsive to a triggering of a comparison, comparing current parameter values of the device with the one or more parameter values of the master golden record for the active mode. The method also includes generating a report comprising differences between the one or more parameters values of the master golden record and the current parameter values of the device. ## Claims ### Claim 1 A method comprising: receiving a master golden record for a device of a plurality of devices in an industrial automation system, wherein the master golden record includes one or more parameter values for the device for a mode of the industrial automation system; identifying an active mode for the industrial process control and automation industrial automation system; responsive to a triggering of a comparison, comparing current parameter values of the device with the one or more parameter values of the master golden record for the active mode; and generating a report comprising differences between the one or more parameters values of the master golden record and the current parameter values of the device. ### Claim 2 (depends on 1) The method of claim 1, wherein the one or more parameter values of the master golden record is set at a time of commissioning. ### Claim 3 (depends on 1) The method of claim 1, further comprising: receiving a schedule including when to trigger a comparison of each device of the plurality of devices. ### Claim 4 (depends on 3) The method of claim 3, further comprising: auditing all user actions of modifying the master golden record, the active mode, or the schedule. ### Claim 5 (depends on 1) The method of claim 1, wherein the report further comprises a number of device comparisons that failed or passed, a number of smart devices that a comparison could not be performed, a number of devices that are cancelled, a number of devices that encountered an issue during execution; and exact configuration parameters that changed from the one or more parameter values of the master golden record. ### Claim 6 (depends on 1) The method of claim 1, further comprising: archiving the report and providing access for future retrieval of the report. ### Claim 7 (depends on 1) The method of claim 1, wherein different master golden records are provided for different modes of the industrial automation system. ### Claim 8 An apparatus comprising: a memory configured to store a master golden record; and a processing device coupled to the memory and configured to: receive the master golden record for a device of a plurality of devices in an industrial automation system, wherein the master golden record includes one or more parameter values for the device for a mode of the industrial automation system; identify an active mode for the industrial automation system; responsive to a triggering of a comparison, compare current parameter values of the device with the one or more parameter values of the master golden record for the active mode; and generate a report comprising differences between the one or more parameters values of the master golden record and the current parameter values of the device. ### Claim 9 (depends on 8) The apparatus of claim 8, wherein the one or more parameter values of the master golden record is set at a time of commissioning. ### Claim 10 (depends on 8) The apparatus of claim 8, wherein the processing device is further configured to: receive a schedule including when to trigger a comparison of each device of the plurality of devices. ### Claim 11 (depends on 10) The apparatus of claim 10, wherein the processing device is further configured to: audit all user actions of modifying the master golden record, the active mode, or the schedule. ### Claim 12 (depends on 8) The apparatus of claim 8, wherein the report further comprises a number of device comparisons that failed or passed, a number of smart devices that a comparison could not be performed, a number of devices that are cancelled, a number of devices that encountered an issue during execution; and exact configuration parameters that changed from the one or more parameter values of the master golden record. ### Claim 13 (depends on 8) The apparatus of claim 8, wherein the processing device is further configured to: archive the report and providing access for future retrieval of the report. ### Claim 14 (depends on 8) The apparatus of claim 8, wherein different master golden records are provided for different modes of the industrial automation system. ### Claim 15 A non-transitory computer readable medium embodying a computer program, the computer program comprising computer readable program code for: receiving a master golden record for a device of a plurality of devices in an industrial automation system, wherein the master golden record includes one or more parameter values for the device for a mode of the industrial automation system; identifying an active mode for the industrial automation system; responsive to a triggering of a comparison, comparing current parameter values of the device with the one or more parameter values of the master golden record for the active mode; and generating a report comprising differences between the one or more parameters values of the master golden record and the current parameter values of the device. ### Claim 16 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the one or more parameter values of the master golden record is set at a time of commissioning. ### Claim 17 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the computer readable program code further comprises computer readable program code for: receiving a schedule including when to trigger a comparison of each device of the plurality of devices. ### Claim 18 (depends on 17) The non-transitory computer readable medium of claim 17, wherein the computer readable program code further comprises computer readable program code for: auditing all user actions of modifying the master golden record, the active mode, or the schedule. ### Claim 19 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the report further comprises a number of device comparisons that failed or passed, a number of smart devices that a comparison could not be performed, a number of devices that are cancelled, a number of devices that encountered an issue during execution; and exact configuration parameters that changed from the one or more parameter values of the master golden record. ### Claim 20 (depends on 15) The non-transitory computer readable medium of claim 15, wherein the computer readable program code further comprises computer readable program code for: archiving the report and providing access for future retrieval of the report.
