Upstream file - System description SVCN

This optional file stores information that is to be returned to the updater during communication with the locking device. Information in this file will return to the integrator system.

It is created during initial programming. Updaters and locking devices can change this file.

Four types of information can be returned with the upstream file:

1. Last unauthorized access attempts: Saves the last two rejected access attempts, the time of the access attempt and the reason for the rejection
2. Priority event list (optional): Saves all battery events and a warning if the blacklist in a locking device is more than 80% full (priority event list is not overwritten on a rolling basis and must be emptied regularly on the updater)
3. Status list (optional): Saves the number of blacklist entries and the locking device temperature
4. Access list (optional): Configurable rolling memory for logging access events
