System Settings Architecture

This page explains the hierarchical structure and organization of all system configuration elements in the OV20i, showing how different setting levels work together to create a cohesive vision system.

Configuration Architecture Overview

Three-Tier Configuration Hierarchy

The OV20i organizes settings into three distinct architectural layers:

Configuration Levels:

• Device-Level Settings - Hardware and system foundation
• Recipe-Level Settings - Inspection-specific configurations
• Global System Settings - Cross-recipe shared resources and policies

Configuration Scope and Inheritance

Setting Relationships:

• Device settings form the foundation for all operations
• Recipe settings inherit device capabilities but define specific behaviors
• Global settings apply system-wide policies that affect all recipes
• Active recipe determines current operational configuration

Device-Level Settings Foundation

Hardware Configuration Layer

Physical System Configuration:

• Network Identity - IP addressing, subnet configuration, protocol assignment
• Digital I/O Assignment - NPN/PNP logic, trigger inputs, status outputs
• Power Management - 19-24 VDC input configuration, thermal protection
• Port Configuration - M12 Ethernet, Micro-USB emergency access, serial communication

note

See:

• Networking: IP/Subnet
• Digital I/O Logic: NPN vs PNP

System Identity and Security

Device-Wide Authentication:

• User Management - Engineer/Supervisor/Operator permission levels
• Access Control - Authentication requirements and session management
• Device Identity - Serial numbers, software versioning, activation status
• Emergency Access - Micro-USB recovery procedures and bypass methods

note

See:

• Users & Permissions
• Use USB for Recovery

Firmware and Software Architecture

System Software Layer:

• Core System Services - Camera control, AI processing, network communication
• Node-RED Platform - Recipe-specific automation workflows (Node-RED lives in each recipe)
• Update Management - Software version control and upgrade procedures
• System Monitoring - Health checks, diagnostic reporting, error handling

Version Management:

• Recipe Compatibility - Older recipes can be opened on newer software versions
• Version Upgrade - Saving recipes updates them to current software version automatically
• Downgrade Limitations - Software downgrades require support assistance and erase all camera data

note

See: Node-RED Basics

Recipe-Level Configuration

Inspection Configuration Hierarchy

Recipe-Specific Settings:

• Imaging Parameters - Exposure, focus, lens settings, lighting configuration
• Template and Alignment - Pattern matching setup, confidence thresholds, search areas
• AI Model Selection - Classification vs Segmentation, training modes, accuracy settings
• Triggering Configuration - Manual, Hardware, PLC, Aligner, or Interval trigger modes

note

See:

• Use the Aligner Tool
• Classifier vs Segmenter
• Triggering Modes (Manual, Digital, Sensor)

Recipe State Management

Active vs Inactive Configuration:

• Single Active Recipe - Only one recipe operational at any time
• Recipe Switching - Activation/deactivation procedures and system state changes
• Configuration Validation - Settings compatibility checks and error detection
• Recipe Dependencies - Template images, training data, and model requirements
• Node-RED Integration - Each recipe contains its own Node-RED automation workflows

Inspection Workflow Architecture

Recipe Execution Pipeline:

• Trigger Processing - Input signal handling and capture initiation
• Image Acquisition - Camera control and image capture procedures
• AI Processing - Model execution and result generation
• Output Communication - Digital I/O, PLC, and HMI result delivery

Global System Settings

Cross-Recipe Shared Resources

System-Wide Data Management:

• Library Storage - Image capture history with automatic cleanup when memory full
• Storage Management - SD card allocation, retention policies, oldest-first deletion
• Training Data Protection - Training images preserved regardless of storage constraints
• Data Export/Import - Recipe backup, restoration, and transfer capabilities
• System Logs - Diagnostic data, error tracking, and performance monitoring
• Small File Storage - Camera can store small reference files (CSV, etc.) for Node-RED access

Storage Hierarchy:

• Training Data - Highest priority, never automatically deleted
• Recent Captures - Newest images preserved first
• Oldest Captures - Automatically deleted when storage nearly full
• Reference Files - Small files for Node-RED workflows (must remain small)

note

See Library & Image Management

Communication and Integration

External System Connectivity:

• Network Protocols - Ethernet/IP, Profinet, TCP communication configuration
• Industrial Integration - PLC communication parameters and data exchange formats
• Node-RED Workflows - Recipe-specific automation logic and third-party system integration
• Remote Monitoring - Web interface access and diagnostic capabilities
• File Access - Small reference files (CSV, etc.) accessible to Node-RED workflows

System-Wide Policies

Operational Governance:

• Default Behaviors - Fallback settings and error handling procedures
• Performance Optimization - System resource allocation and processing priorities
• Maintenance Schedules - Automated cleanup, health checks, and system validation
• Data Retention - Archive policies, storage limits, and data lifecycle management

Configuration Management

Settings Persistence and Recovery

Configuration Backup Architecture:

• Recipe Export/Import - Individual recipe backup and restoration
• System Configuration - Device-level settings preservation
• Factory Reset - Complete system restoration to default state
• Emergency Recovery - USB-based configuration access and repair

Version Compatibility:

• Software Updates - Settings migration during system upgrades
• Recipe Version Handling - Older recipes open on newer software, saving updates version
• Downgrade Restrictions - Software downgrades require support assistance and erase all data
• Backward Compatibility - Legacy configuration support with automatic version conversion

Change Management and Validation

Configuration Control:

• Change Tracking - Modification history and audit trails
• Settings Validation - Conflict detection and compatibility checking
• Rollback Procedures - Recovery from failed configuration changes
• Testing Workflows - Configuration validation and performance verification

System State Consistency

Architectural Integrity:

• Configuration Dependencies - Cross-layer setting relationships and validation
• Resource Allocation - System resource management across configuration levels
• Performance Impact - Setting changes and system performance implications
• Operational Continuity - Configuration changes without production disruption
