What Are Data Links?
Section 5-1
3.
Personal computers can be used with the following systems. Refer to 1-1-
1 What Is the Controller Link? for example system configurations.
• An Optical Bus or Optical Ring Controller Link Board can be used in a
system that contains only Optical Bus Controller Link Units (model
numbers ending with CLK11.)
• An Optical Bus or Optical Ring Controller Link Board can be used in a
system that contains only Optical Bus/Optical Ring H-PCF Controller
Link Units (model numbers ending with CLK12 or CLK12-V1) operat-
ing in token-bus mode.
• Controller Link PCI Support Boards can be used in any system.

Differences Between Manual and Automatic Setting
Note
1.
The following are true for computer nodes (i.e., computers with a Controller
Link Support Board mounted).
• The data link starting position is fixed.
• Because areas such as bit areas and DM are not available, areas must
be made available on the computer for linking.
• Automatically set data links cannot be started from the Controller Link
Support Board.
• The Controller Link Support Board can participate in automatically set
data links.
Item
Manual setting
Automatic setting
Determination of
nodes to be in a
data link
Determined by setting data link
tables.
Determined by the data link
parameters set in the data link
startup node (the node used to
start the data links).
Data link settings Set in data link tables that are
set in the nodes to participate
in data links.
Determined by the data link
parameters set in the data link
startup node (the node used to
start the data links).
Data link areas 1
and 2
In each node, Area 1 and Area
2 are selected from bit areas
(IR, CIO, and LR Areas) and
Data Memory (DM and EM
Areas).
However, areas 1 and 2 cannot
be set in the same memory
area.
Area 1 is selected from bit
areas (IR, CIO, and LR Areas)
and Area 2 is selected from
Data Memory (DM and EM
Areas).
Refresh starting
word
Can be set freely in each node.
(See note 1.))
Can be set freely. (See note a))
Data link status
area
Selected from bit areas (IR,
CIO, and LR Areas) and Data
Memory (DM and EM Areas) in
each node.
Selected from bit areas (IR or
CIO Areas).
Refresh
sequence
Can be set in each node freely. Node addresses are in ascend-
ing order.
Data reception
It is possible to set in each
node whether the entire data or
a part of the data sent from
another node is received. It is
also possible to not receive the
data sent from a specific node.
(See note 2.))
The entire data sent from each
node that is participating in the
data link is received.
Data transmission The send sizes can be set
freely in each node. It is also
possible for certain node not to
send data. (See note 2.))
In Area 1 and Area 2, data
send sizes are the same in
each node.
