Establishing a connection to the protection device
After all devices have been set correctly, and the Dial-up connection in the substation is active, a
connection to the protection device can be established.
In the window „Open device""Ethernet" is selected under „Connection type" and confirmed with
„OK".
For the set-up and termination of a connection to the protection device, the following order must be
followed:
1. Open the substation with the protection devices that are to be operated in DIGSI 4.
2. Open the Dial-up connection via the corresponding desktop icon.
3. Enter user name and password and dial.
4. Open the first protection device and establish the connection with the connection type
"Ethernet".
NOTE: This must be done before the automatic termination by the Dial-up connection or the
router. If necessary increase the Idle time settings.
While the protection device is online, the connection is not automatically terminated,
as DIGSI 4 constantly transmits data for the purposes of line monitoring.
5. After closing the first protection device, immediately dial up the second protection device.
NOTE: See the note under number 4.
After closing the last protection device, terminate the Dial-up connection manually!
Good luck!
