Historizing System Configuration Records

Several system configuration records in FMS Explorer are historized so that you can view any changes made to a record over time. Each historized system configuration record has a "change begin" and "change end" time window, so you can scroll back and forth between changes for any given record.

The following types of system records are historized.

• Node creation and changes
• Validation rule creation and changes
• Estimation rule creation and changes
• Purged device data actions

Historized records may be useful in the following situations.

• You have recently acquired a new field and need to rename all devices. By performing an audit request from before the acquisition you can view the old device names.
• You must change validation rules to match a hardware change, but data is still coming in from the device from before the change and you must validate data under the old rules.
• You know that a field device is going to be offline for three hours tomorrow. You can proactively “deactivate” the device for those three hours in the system so it doesn’t try to get data during the offline period. The measurement system will mark the database accordingly.

Saving a Historized Record

After creating or editing a Node, validation rule, or estimation rule, you will be asked to historize the record change as part of the save action. Select effective change begin and change end dates. Options are Indefinite (no specific time; effectively all time), and Choose date/time (C) (the specific date/time you select).

You can optionally select an audit category from the drop-down menu to provide a more detailed audit trail for the record. Each audit category type contains configured options of available audit categories. Categories are configured on the Admin menu. See Configuring Audit Categories for more information.

You can also optionally enter a comment in the text box to explain the change. This comment becomes part of the audit record, and can help to identify the context for the change.

See the following topics for information about saving this type of FMS record.

• Creating Station Group Nodes and/or Viewing and Editing Station Group Node Properties
• Configuring Validation Rules
• Configuring Estimation Rules

Using the Historization Navigator

Many dialog boxes in the measurement system contain a Historization Navigator to easily access sequential historized records, where applicable. Historization views records as of "now" (system Contract time).

The following fields are displayed in the historization navigator.

Configuring Historization

See Configuring System Options for more information about administrative tasks related to historization, including default configuration change effective dates, and allowing changes to be effective in the past.
