[Section]/Item Value Range Description
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.
[Section]/Item Value Range Description
[IEC-101 MASTER
SESSION x] Settings for each session utilized
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.
DL Address Length: 0, 1 or 2 This parameter sets the number of octets used to
define the data link address for the session. A
value of 0 is only permitted when balanced mode
is used.
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 sets the number of octets used for
the common address of ASDU for each sector for
this session.
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.
COT Octet Count: 1 or 2 This parameter sets the number of octets used for
the COT field in each message. If a value of 2 is
selected, the value entered for the Originator
Address For COT will accompany each message
from the controlling unit.
Originator Address For
COT: 0 to 255 This parameter sets the address to be passed
with each message when the COT Octet Count
parameter is set to 2.
Failure Delay: 0 to 2000 This parameter sets the minimum number of
seconds to delay before polling this session when
it is not online. This parameter is only used in
unbalanced mode.
Confirm Timeout: 0 to 2^32-1 This parameter sets the number of milliseconds to
wait for a confirm response from the controlled
device.
Retry Count: 0 to 255 This parameter sets the number of retries to be
performed on the controlled device when a
communication error occurs.
