Core Functions

Change Tracking

Version Control tables maintain a summary, summaries by Module and Configuration Table, of the tracking current version versions and last modification modifications of all solution elements in a solution. This data ensures consistency when connecting to Runtime for online changes.

Cross-Reference Engine

The Cross-Reference system powersPowers multiple analysis features:

  • Find Results Panel in Designer
  • Use Count calculations
  • Unused Objects detection
  • Impact analysis for changes

Limitations

Important: Cross-Reference only detects direct object usage. Indirect references are not tracked:

Indirect Usage TypeExampleImpact
String referencesAsset("/folder1/tag1")Not detected
.Link propertyTagReference via stringNot tracked
API accessExternal applicationsNot visible
Dynamic referencesScript-generated namesNot found
OPC UA/MQTTExternal consumersNot tracked

With Runtime

The Version Control data enables:

  • Online configuration verification
  • Hot reload compatibility checks
  • Change synchronization
  • Version mismatch detection

Best Practices Checklist

Regular Maintenance

  •  Review Recent Changes daily
  •  Check Unused Objects weekly
  •  Monitor Use Count for optimization
  •  Verify Cross-References before deletion

Before Removing Objects

  •  Check Unused Objects table
  •  Verify no indirect references
  •  Confirm no external usage
  •  Use Find Results for verification
  •  Document removal reason

Change Management

  •  Configure appropriate auto-delete settings
  •  Keep audit trail for compliance
  •  Export changes for version control
  •  Review Version Control before deployment
