Configuration parameters for localized substation automation ---
address block 69
The unit must be informed as to whether it is used as
a component in a localized substation automation
system or not. If a central unit is not connected, no
further information is required, since the unit is pre-
set to ”LSA =
NON---EXIST
”.
Otherwise block 69 contains several questions
which must be answered. For this, the codeword
must be entered (refer Section 5.3.1). The entered
data must be coordinated with the central unit. They
refer to the Baud-rate of the serial data transfer. The
identification address of the individual device and its
measurement and fault data has been parameter-
ized under addresses 7009 and 7010 (refer Section
5.3.2).
They are valid also for identification of the device in
the control centre.
Block 69 can be called-up by paging with keys
Ý ß
or
by directly addressing with
DA 6 9 0 0 E
.
In addition, annunciations and messages which
should be transmitted to the control centre must be
coordinated with the central station. All annunci-
ations which can be processed by the LSA are
stored within the device in a separate table. For allo-
cation of LSA---compatible annunciations, Table 5.7
is valid.

Note for LSA:
The parameters DEVICE ADDress and FEEDER ADDress which had been entered to the device
under this item are now set in the address block 70 when setting the operating parameters, refer Section 5.3.2.
They are valid for the operation interface for operation with a personal computer as well as for the LSA interface.
If the device is connected to a central control station then these parameters should now be rechecked:
Address 7009
DEVICE ADD
0 to 255
Address 7010
FEEDER ADD
0 to 255
The following measured values are transmitted:
Measured value: current in phase L1
Measured value: current in phase L2
Measured value: current in phase L3
Measured value: earth current
