6.3.2 Initial displays --- address blocks 00 and 10
When the relay is switched on or the operator terminal has been connected, firstly the address 0000 and the
type identification of the relay appears. All Siemens relays have an MLFB (machine readable type number).
When the device is operative and displays a quiescent message, any desired address can be reached e.g. by
pressing the direct address key
DA
followed by the address number.

The relay introduces itself by giving its type number
and the version of firmware with which it is
equipped. The second display line shows the com-
plete ordering designation.
After address 1000, the functional parameters begin. Further address possibilities are listed under ”Annunci-
ations” and ”Tests”.

6.3.3 Power system data --- address block 11
The relay requests basic data of the power system and the switchgear. The rated current (address 1105) is of
no concern for the actual protection functions of the device but is used for the calculation of the operational
measured values (refer Section 6.4).
