6. Set the data link mode.
Note a) When using fewer than 33 nodes, make sure that the Wired Net-
work 62 Node Enable Bit if the DM Parameter Area software
switch is turned OFF to restrict the network to 32 nodes maximum.
To construct a network that uses a node address higher than 32,
all nodes must use the CS1W-CLK21-V1 or CJ1W-CLK21-V1.
b) Only node addresses 1 through 32 can be used on networks for
which 62 nodes have not been enabled.
c) Be sure that the data link mode in the data link parameters in the
DM Area is set to 00 when using manually set data links.
d) When using the 8-bit storage format, make sure that the relevant
locations in the DM Parameter Area are set to 0. The storage for-
mat used by all models other than CS1W-CLK21-V1, CS1W-
CLK21, CJ1W-CLK21-V1, and CJ1W-CLK21 is fixed at 8-bit, re-
gardless of the setting.
7. Register the data link tables by making the following settings for each
node.
Note Offsets are used to control where data is placed within the receive
area.

Enable 62 nodes for a
wired network. Use Support Software
for the PLC or the Pro-
gramming Console. All nodes
Note: This setting
must be made to con-
struct a network that
uses a node address
higher than 32 (See
note a.)

Set data link mode to
manual. Use Support Software
for the PLC or the Pro-
gramming Console.
(See note b.) Data link startup node
only
The node that is used
to start the data links
is called the startup
node. It is necessary
to decide beforehand
which node will be the
startup node.
