Configuration versioning

Configuration versioning is the practice of assigning identifiable versions to a system, application, device, process, or equipment configuration as it changes over time. It commonly refers to keeping a controlled history of settings, parameters, logic, mappings, templates, and other non-code configuration items so current and prior states can be identified and compared.

In industrial and regulated environments, configuration versioning is used to understand what configuration was active at a given time, who changed it, when it changed, and what changed between versions. This can apply to MES rules, ERP integration mappings, PLC or SCADA parameters, electronic forms, work instruction settings, quality workflows, user-role configurations, and similar controlled setup data.

Configuration versioning does not mean any change is automatically approved or released. It is about maintaining version identity and history. Approval workflows, change control, and document control may be related, but they are separate controls.

What it typically includes

• Version numbers, revision IDs, or other unique identifiers for a configuration state

• Records of additions, removals, or edits to configuration items

• Date, time, and user attribution for changes

• Comparison between versions

• Rollback or restoration to a prior known configuration, where supported

• Linkage to deployment, release, or change records in broader governance processes

Common confusion

Configuration versioning is often confused with document version control and source code version control. Document version control applies to files such as SOPs, specifications, or controlled forms. Source code version control applies to software code. Configuration versioning focuses on operational settings and structured system behavior that may exist outside code files or formal documents.

It is also distinct from a full audit trail. An audit trail may record every event or field-level change. Configuration versioning usually emphasizes named, recoverable configuration states and their revision history.

Manufacturing context

In manufacturing systems, configuration versioning commonly appears where system behavior must remain stable and explainable across production runs, quality events, or integration updates. Examples include versioned routing parameters in MES, revised inspection plan settings, changes to label templates, or updates to ERP-to-MES field mappings. The goal is to preserve a reliable record of which configuration was in effect for a given operation or period.
