Node Addresses - Omron SYSMAC CS1W-RPT01 Operation Manual

Node Addresses

Note
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.

Node
Set the node address using a small flat-blade screwdriver, being careful not to
damage the rotary switches.
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-
ther communications will stop, or the INS indicator will not light and you will
be unable to participate in the Network.
4. 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 between 1 and 32. In a network containing
pre-version-1 models, it is not possible to construct a network that uses a
node address higher than 32.
Turn ON 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 maximum. If a different value is specified, the net-
work will be incorrectly configured.
5. 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 of the DM Parameter
Area software switch of all nodes must be turned ON to enable 62 nodes
maximum. If a different value is specified, the network will not be correctly
configured.
Note: The factory default settings are shown.
