Point Index: Information number for the point
Database Index: The MVI56-103M database location where the value will be
copied. Special attention should be considered since the type of addressing will
depend on the ASDU type:
ASDU Type
DB Addressing
1
Bit address with each point occupying 2 bits
2
Bit address with each point occupying 2 bits
3
Word address with each point occupying 4 words
4
Double-word address for the single float value
5
Byte address with each point occupying 12 bytes
9
Word address with each point occupying 9 words
205
SIEMENS Meter Data (Private Range)
Double-word address for each meter point
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, refer to the [IEC-103
Master Commands] section:
[IEC-103 Master Commands]
#
# Enable code field is as follows:
# 0 = Disabled
# 1 = Enabled with Poll Interval (seconds) utilized
# 2 = Conditional (executed when point in database changes)
#
# Database Index is the location in the module's database to use as the source
