The Download Service can be stopped without adversely affecting the system. Stopping the Download Service
will stop all outgoing messages to the controllers.
The Download Service periodically checks the configuration known to be stored in the controller and compares
this with the current configuration in the GX database. If the two don't match, a new configuration is
downloaded to the controller.
