16.1.11 Options for Modifying the Message Number Assignment of a Project
In the "Message number" tab of the SIMATIC manager you can preset the way message numbers
will be assigned (Menu command Options > Customize) to future projects and libraries. In this tab
you determine whether the message numbers are to be assigned only to the CPU (CPU-oriented)
or only to the project (project-oriented). You can also choose "Always ask for setting" if you want to
specify the assignment later.
If the initially set default "CPU-oriented" or "project-oriented" was active when you created the
project or library, you can no longer change the type of message number assignment for this
project or library.
If you have set "project-oriented" unique message number assignment and want to set
"CPU-oriented" unique assignment proceed as follows:
1. In SIMATIC Manager, select the corresponding project or library.
2. Select menu command File > Save As.
3. Enable the "With rearrangement" check box In the next dialog box and enter a new name.
4. Start the process with "Save As" and confirm your entries with "OK".
5. In one of the next dialogs you can specify "CPU-oriented" unique message number
assignments.
You can use the File > Delete command to delete the original project or library.
