Use Balanced Mode
Yes or No
This parameter specifies if the port will use balanced mode. If balanced mode is
used, only one controlled station will be permitted on the port. If unbalanced
mode is used, multiple controlled stations can be used on a port. Select Yes to
use balanced mode and No to use unbalanced mode.
5.2.4 [IEC-101 Master Session x]
This section is used to define session x which runs on Port x. The session
sections of the configuration file are determined by the number of sessions set in
the configuration file. The sessions are referenced by a zero based index value.
For example, if the module is configured for four sessions, the configuration file
should contain sections for sessions 0 to 3 (that is, [IEC-101 Master Session 0] to
[IEC-101 Master Session 3]. Each of these sections will define the characteristics
of the specific controlled device to be interfaced.
Communication Port
0 or 1
This parameter sets the port to which the controlled device is connected. On this
module, values of 0 and 1 are permitted.
Sector Count
1 to 5
This parameter sets the number of sectors contained in this controlled device.
The range of values is from 1 to 5. A sector section is required for each sector in
a session to define its database and settings.
Data Link Address
0 to 254 or 0 to 65534
This parameter uniquely defines the data link address for this unit on the
communication channel The ranges of values depends on the value set in the DL
Address Length parameter.
Common address of ASDU Len
1 or 2
This parameter specifies the number of octets used for the common address of
ASDU. This parameter must be set the same for all devices on the network.
Inform. Object address Len
1, 2 or 3
This parameter sets the number of octets used to specify the address for an
information object in each sector for this session.
