Offline Licensing File Types
When working with systems that cannot connect directly to the internet for license activation, WinCC OA uses a file-based offline licensing workflow. This process involves transferring specific file types between online and offline systems to manage license operations securely.
The following file types are used in offline licensing operations:
| File Type | Description | Usage in Workflow |
|---|---|---|
| .WibuCmRaC, .RAC | Remote Access Update Certificate | Contains license updates or activation data. Generated on an online PC and transferred to the target offline system for license installation. |
| .WibuCmRaU, .RAU | Remote Access Update Request | Contains license requests or system information. Created on the offline target system and transferred to an online PC for processing. |
| .Receipt | Transaction Receipt | Provides confirmation that a licensing operation was successfully completed. Used for verification, audit trails, and tracking offline licensing transactions.1 |
These files enable secure license management in air-gapped or restricted network environments where direct internet connectivity is not available. The typical workflow involves creating request files on the offline system, processing them on an online system, and transferring the resulting certificate files back to complete the licensing operation.
For detailed step-by-step instructions on using these files in offline licensing workflows, see License Information Panel.
