Configuring source protection in the Logix Designer application Chapter 4
Use descriptive names to help identify the purpose of the source. For instance, a
source key used to secure components that field engineers require access might be
named, Field Engineer.
Important: If the same source keys will be used with version 18 and earlier and
version 19 and later of the application, begin each source key with a
lowercase character a-z, or an underscore character ( _ ), and use only
characters lowercase a-z, 0-9 , or an underscore character ( _ ) within the
source keys.
If you use source key names in version 19 and later of the application, and
your source keys are IEC61131-3 compliant, your source keys will still work
in version 18 and earlier.
Follow these steps to apply a source key to one or more components.
1. Open an offline project file.
2. On the menu bar, click Tools, then click Security, and then click
Configure Source Protection.
3. In the Source Protection Configuration dialog box, select one or more
components that require protection and click Protect.
