Controller Configuration Data
Each controller stores a variety of configuration data (for example, its geographic location and what type of hardware is attached to it). This configuration data is checked for integrity each time the controller starts up to make sure that the controller does not run with corrupted data. It is also automatically synced with the Valhalla server at configurable intervals. The options can be modified both through the main Valhalla server and from a direct LAN connection to the controller with the local web server.
