Set the node address using a small flat-blade screwdriver, being careful not to
damage the rotary switches.
1. Always turn OFF the PLC's power before setting the unit number.
2. When setting a Unit for the first time or changing the existing setting, create
a I/O table in the PLC's CPU Unit.
3. Do not set the same unit number twice within the same PLC. An error will
occur if the same unit number is set for two different Unit, and the CPU Unit
will not be able to recognize the Units.
4. When the Unit is recognized by the PLC's CPU Unit, "NS" will be shown in
the I/O table displayed for the CX-Programmer programming device.
5. The default setting is "0."
6. The unit number determines the words used by the Controller Link Unit in
PLC memory.
Set the node addresses of each Unit on the Network using the rotary switches
on the front of the Unit. The node address is used to identify each node in the
Network can be set to any number between 01 and 32.
Note: The factory default settings are shown above.

1. When all of the following conditions are satisfied, node addresses can be
set between 01 and 62, and the network can contain up to 62 nodes.
a) All nodes in the Controller Link Network use CS1W-CLK21-V1, CS1W-
CLK23, CJ1W-CLK21-V1, or CJ1W-CLK23 Units.
b) The Wired Network 62 Node Enable Bit in the DM Parameter Area
software switches (bit 11 of D30000 + 100 × Unit No.) of all nodes is
turned ON.
c) At least one CS1W-RPT01 Repeater Unit is connected and the num-
ber of nodes in a single segment does not exceed 31.
2. Always turn OFF the PLC's power before setting the node addresses.
3. Do not set the same node address twice within the same network. An error
will occur if the same address is set for two different nodes. The ERC indi-
cator on the front of the Unit will light (Communications Error Flag) and ei-
