Application Precautions
Section 1-5
• Set routing tables at all the nodes in all the networks when multiple net-
works are connected.
• 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.
• 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 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.

Communications error type
Data link areas
A node separates from the net-
work while a data link is running.
Data received immediately prior to the error
continues to be refreshed in the data link
areas of the relevant nodes.
A node does not join the network
after the data links start.
Zero (0) data continues to be refreshed in
the data link areas of the relevant nodes.
