Configuration commonly refers to the defined set of options, parameters, structures, and relationships that determine how a system, product, or process is set up to operate. In industrial and manufacturing environments, configuration typically describes how equipment, software, data models, and workflows are arranged and parameterized to meet specific operational and regulatory requirements.
Configuration in industrial and manufacturing systems
In regulated manufacturing and industrial operations, configuration usually includes:
- System settings and parameters such as MES, ERP, SCADA, or historian options, user roles, limits, and thresholds.
- Process definitions including routings, recipes, bills of materials, work centers, and quality plans as stored in MES/ERP or other control systems.
- Equipment and OT setup such as PLC logic options, device addresses, communication protocols, and alarm thresholds.
- Data models like master data structures, material codes, specification limits, and traceability relationships.
- Application behavior including enabled features, workflow rules, approval flows, and integration endpoints.
Configuration is typically managed through controlled interfaces (for example, admin consoles, configuration files, or parameter tables) and is often subject to governance, change control, and versioning, especially in regulated environments.
What configuration is and is not
Configuration generally includes how a system behaves without changing its underlying source code or physical design. It is distinct from:
- Custom development which involves writing or modifying code beyond configurable options.
- Physical design changes such as re-engineering a machine or rewriting control logic, as opposed to selecting available parameter values.
- Operational state like current machine status, in-process orders, or live sensor readings, which are outcomes influenced by configuration but not configuration themselves.
Operational role of configuration
In day-to-day operations, configuration shows up as:
- Which production lines are enabled for a product and which routing they follow.
- Which quality checks appear in a digital work instruction at each operation.
- What alarm limits are used for critical parameters on a process unit.
- Which data fields are mandatory for batch records or device history records.
- How data flows between OT systems, MES, ERP, and quality systems.
Because configuration affects how work is executed and recorded, it is often treated as a controlled object, with documented approvals, testing, and traceability of changes.
Common confusion
- Configuration vs. master data: Master data (such as material masters or customer records) defines business objects, while configuration defines system behavior and rules that use that data. In many systems, they are closely related and sometimes maintained in the same tools but governed separately.
- Configuration vs. recipe/parameter set: A process recipe or parameter set can be viewed as a type of configuration specific to a product or batch. Broader configuration includes global system options, role definitions, and workflows beyond individual recipes.
- Configuration vs. validation/qualification: Configuration is the setup itself. Validation and qualification activities are the documented processes that provide evidence that a configured system is fit for its intended use.
Configuration management
Configuration management refers to the controlled processes and tools used to define, document, track, review, and change configurations over time. In manufacturing IT/OT environments this often involves:
- Maintaining an inventory of configured systems and their versions.
- Using change control workflows for edits to key parameters.
- Capturing who changed what, when, and why for auditability.
- Coordinating configuration with testing, deployment, and training.
This reduces the risk of unintended behavior in production systems and supports internal and external audits.
