8 Settings files and offline system configuration

All system settings are recorded locally in “Settings” files. These files are updated each time a setting is modified and automatically updated every 30 minutes.

NOTE: Both CPUs must have the same configuration and settings at all times, otherwise unpredictable system behavior could occur. Every 30 minutes the system compares the settings between the CPUs. If a mismatch in settings between CPUs does occur, an event will be generated. A mismatch should be correctly immediately.

The HMI has a special offline mode. Offline mode disconnects the HMI from a live system and allows users to modify and save settings. Later, once reconnected to a live system, these saved settings can be written to the system.

The following operations are permitted in offline mode:

•User Settings activities

•Maintenance activities

•User Administration

Another convenience offline mode provides is the ability to work on protection settings prior to the arrival of the switchgear. See Commissioning the switchgear on page 11 for more details.
