Adding the Real-Time profile package to a model
1. Ensure that you have Database Write access permissions to the Model's Database.
2. Open the Model to which you want to apply the Real-Time profile package.
3. On the Tools menu, click Add Profile.
4. Select the Real-Time entry, and then click OK.

• Do not make changes to the Real-Time profile. Any changes you make will be lost when the profile is updated.
Note that you can create Tag Definitions outside of the Real-Time profile, and link those Tag Definitions to Stereotypes in the Real-Time profile. When the Real-Time profile is updated, the links will not be broken.
• Do not create copies of the Real-Time profile within a model, or create copies of the Real-Time profile through XMI Import/Export. The copies of the Real-Time profile will not work correctly and you will not be able to update the copies through the Update All Profiles command.
