Omron CJ1W-CLK21-V1 ユーザーズマニュアル

When data links are active in the existing network, check the following items
before adding nodes to the network. If the inappropriate data link tables or
parameters are set, the system may not operate properly.

• If the new node will participate in user-set data links, make sure that the

appropriate data link tables are set in the corresponding nodes.

• If the new node will not participate in user-set data links, make sure that

the data link tables of the corresponding nodes are deleted.

Setting the 
Repeater Unit

Setting the 
additional 
nodes

Connecting 
and checking 
the cables

Check the operating 
conditions and setting 
status of the existing 
network.

Set the baud rate and 
terminating resistance 
switch on the 
Repeater Unit.

(1) Number of nodes registered in network and 

node addresses

(2) Baud rate setting
(3) CS1W-RPT01 Repeater Unit connection
(4) Data link mode when data links are 

active/inactive

(5) Wired Network 62 Node Enable Bit setting in 

the DM Parameter Area

(6) Ladder program (program that includes the 

new nodes)

System Configuration before Adding Nodes

CS1W-RPT01 
Repeater Unit

Prepare the 
nodes to be 
added.

Set the Control-
ler Link settings 
for the new no-
des.

Turn ON the 
power to the 
new nodes.

Set the DM 
Area 
parameters.

Turn OFF the 
power to the 
new nodes.

(1) Set the node address to a number that is 

not being used by another node on the 
network.

(2) Set the baud rate to match the settings for 

the existing network and Repeater Unit.

(3) Set the terminating resistance switch: Turn 

ON the terminating resistance for the nodes 
at both ends of the network (segment) only.

(1) Create I/O tables
(2) Transfer user programs, etc.

Do not connect the communications cables yet.

(1) Set the polling/polled node setting to Polled.
(2) Set the Wired Network 62 Node Enable Bit to match the setting for 

the existing network. 
Check that the error indicators (ERC and ERH) are not lit. 
(When the node address is set to 33 or higher, the ERC indicator 
may turn ON. Turn ON the Wired Network 62 Node Enable Bit (to 
enable 62 nodes), turn ON the power again, and check that the 
ERC indicator is OFF.

System Configuration after Adding Nodes

CS1W-RPT01 
Repeater Unit

The cable to the new 
node is not connected.

Connect the 
communications 
cables.

Turn ON the 
power to the 
Repeater Unit.

Turn ON the 
power to the 
new nodes.

Return the 
polling/polled node 
setting in the DM Area 
parameters to Polling.

Check that the PWR indicator is lit.

Join the new node to the existing network.
The node is participating in the network normally if the INS 
indicator is lit and the ERC and ERH indications are not lit.

System Configuration after Adding Nodes

CS1W-RPT01 
Repeater Unit

The cable to the new 
node is connected.

(1) Set the baud rate to match the settings for the existing network.
(2) Set the terminating resistance switch: Turn ON the terminating resistance for 

the Repeater Unit if it is at the end of the segment.

(Do not connect the communications cables yet.)
