CS-series Optical Bus Controller Link Units
The node address can be set to any value between 01 and 32.
Set the node address using a small flat-blade screwdriver, being careful not to damage the rotary switches.
Note 1. Always turn OFF the PLC's power before setting the node address.
2. 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 indicator on the front of the Unit will light (Communi-
cations Error Flag) and either communications will stop, or the INS indicator will not light and you will
be unable to participate in the Network.
3. The send sequence for the data link areas is determined according to the sequence of node address-
es for automatically set data links.
4. Assign node addresses consecutively beginning from 01 whenever possible to minimize Network
construction time.
