Operation in the Operating State
8.7 Change Device Settings
The communication protocols IEC 60870-5-103, IEC 60870-5-104, IEC 61850, DNP or Modbus TCP can be used
for switching the settings groups via a communication connection.
In order to use a CFC chart for switching, you must create a new CFC chart in DIGSI 5. Create the CFC chart in
the DIGSI 5 project tree under Name of the device → Charts → Add new chart. Link the signals that control
settings group switching in the CFC chart.

The device starts in this mode after a DCF upload (offline mode) with active settings group 1. The device is
only informed of a settings group change via the substation automation technology. As long as the substa-
tion automation technology command is pending, protection runs using the settings from active settings
group 1.
If the Control mode is changed in online mode (settings changes via DIGSI 5 or the on-site operation
panel), the device continues to run with the last active settings group. If a substation automation tech-
nology command for a settings group change is sent or the mode for settings group switching is changed,
this state ends. In the case of a device warm start, the device starts in the mode of the most recently active
settings group.
