ASDU Type DB Addressing
5 Byte address with each point occupying 12 bytes
9 Word address with each point occupying 9 words
For example, in order to configure the following points:
Time-tagged message point with information number 17 (teleprotection
active) and distance protection function (128). The value will be copied to bits
0 and 1 in word 1 (second word) in the module's database.
Measurands I point with information number 144 (measurands I) and
overcurrent protection function (160). The value will be copied to word 50 in
the module's database.
The following configuration information should be entered:
# ASDU Database Function Point
# Type Index Code Index
START
1 16 128 17
1 50 160 144
END
Every time the module responds with a Class 1 or Class 2 poll with these points,
the module will update its value to the database.
All the points configured in this section are sent from the slave to the master. The
protocol specification refers to this data flow as the Monitor Direction.
This step should be repeated for each sector.
Step 6 - Command Configuration (Control Direction)
The user might also configure the master to send commands to slaves. The IEC
60870-5-103 protocol specification refers to this data flow as Control Direction.
The commands include general commands, interrogation requests, and time
synchronization requests. In order to configure a command, the user should refer
to the [IEC-103 Master Commands] section:
[IEC-103 Master Commands]
# Enable Database Poll Session Sector Data Func Point Ovrd Ovrd
# Code Index Interval Index Index Type Code Index Flag Val
START
1 0 0 0 0 6 255 0 0 0
1 10 0 0 0 7 255 0 0 0
END
When sending a General Command, the user might associate the source data
with a register in the MVI46-103M database to be sent to the remote slave. The
following example will send 8 commands to the slave configured as Session
0/Sector 0. When using a General Command, the bit addressing should be used:
# Enable DB Poll Session Sector Data Func Point Ovrd Ovrd
# Code Index Interval Index Index Type Code Index Flag Val
