Runtime issues

By default most output operations during runtime occur in the [DATA] or [RUN] location (see below for details). By default CitectSCADA configures the [RUN] location to the project directory. If you intend on making the project directory read-only, you need to modify the path(s) to a suitable read-write location.

Any files in your top-level project that require runtime read-write access have to be located outside of the project folder.
