Reference
Port numbers are assigned to bit addresses in the PLC in units of 16 points, starting from the
channel corresponding to the node address set with the DIP switches.
(This does not apply if a configurator is used to assign port numbers.)

Node address
Node address
(NN) CH and (MM) CH as indicated above represent PLC channel addresses corresponding
to node address nn.
As for nn, nn+1, nn+2, etc., bit addresses corresponding to each node address are occupied
in accordance with the numbers of I/O points used. Accordingly, exercise caution to prevent
node address duplication.

Setting Example
(1) Example for when using only DeviceNet
It is how to establish the setting when using DeviceNet to 16 points of each input and output from the top
of the standard I/O ports, and no other I/O port (for I/O board, etc.) is to be used.
* The figure shown below is XSEL-R/S series. The setting should be the same for XSEL-RA/SA series.
(Except for I/O Parameter No. 225)
Standard Input Port No.0 to 15
Standard Output Port No.300 to 315
(DeviceNet board)
Not Applicable (I/O board)
