• Set routing tables at all the nodes in all the networks when multiple net-
works are connected.

Routing tables are necessary at all the nodes regardless.
• When using the SEND/RECV or CMND instructions on a PLC for which
routing tables have been set, be sure to specify the network addresses
that are set in the routing tables.
• When using manually set data links, delete the data link tables from all
nodes not participating in the data links.
• Do not transfer (write) routing tables when data links are active (i.e.,
started). CPU Bus Units and Communications Units are reset when rout-
ing tables are transferred.
• Do not restart or reset the polling node while data links are active.
• The following table shows the status of the data link refresh areas when a
node registered in the data link table generates a communications error.
Communications error type
A node separates from the net-
work while a data link is running.
A node does not join the network
after the data links start.
• When CS1W-CLK21-V1, CS1W-CLK23, CJ1W-CLK21-V1, and CJ1W-
CLK23 Units are used with other models in the same network, set the
node addresses of all nodes to between 1 and 32. It is not possible to
construct a network that uses a node address higher than 32 in a network
that includes pre-version-1 models.
Turn OFF the Wired Network 62 Node Enable Bit (bit 11 of D30000 + 100
× Unit No.) in the DM Parameter Area software switch of all CS1W-
CLK21-V1, CS1W-CLK23, CJ1W-CLK21-V1, and CJ1W-CLK23 Units to
restrict the network to 32 nodes max. If a different value is specified, the
network will be incorrectly configured.
• To construct a network that uses a node address higher than 32, it is nec-
essary for all nodes to be CS1W-CLK21-V1, CS1W-CLK23, CJ1W-
CLK21-V1, or CJ1W-CLK23 Units.
In addition, the Wired Network 62 Node Enable Bit in the DM Parameter
Area software switches of all nodes must turned ON to enable 62 nodes
maximum. If a different value is specified, the network will not be correctly
configured.
• The Wired Network 62 Node Enable Bit in the DM Parameter Area soft-
ware switches of CS1W-CLK21-V1, CS1W-CLK23, CJ1W-CLK21-V1,
and CJ1W-CLK23 Units is read when the Unit is restarted.
• When using automatic data link creation with 1:N allocation, all nodes
must be CS1W-CLK21-V1, CS1W-CLK23, CJ1W-CLK21-V1, or CJ1W-
CLK23 Controller Link Units. Other models cannot participate in data links
that employ 1:N allocations.

Data received immediately prior to the error
continues to be refreshed in the data link
areas of the relevant nodes.
Zero (0) data continues to be refreshed in
the data link areas of the relevant nodes.
