MVI69-101M ♦ CompactLogix or MicroLogix Platform
IEC 60870-5-101 Master Communication Module
Value Range Description
1 to 65535 This value represents the number of milliseconds
to wait on a port from the time the first character is
received until the last character in the longest
message received on the port. This parameter
should be set dependent on the baud rate. A
value of 2000 should work with most applications.
Yes or No This parameter specifies if the single E5 character
will be used for ACK messages.
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.
Value Range Description
Settings for each session utilized
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.
This parameter sets the number of sectors
1 to 5
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.
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.
0 to 254 or 0 This parameter uniquely defines the data link
to 65534 address for this unit on the communication
channel The ranges of values depends on the
value set in the DL Address Length parameter.
1 or 2 This parameter sets the number of octets used for
the common address of ASDU for each sector for
this session.
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.
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.
0 to 255 This parameter sets the address to be passed
with each message when the COT Octet Count
parameter is set to 2.
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.
