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.
3.6 Standard I/O Ports of XSEL Controller
For the standard I/O ports of XSEL controller, it is possible to change the specified functions except for the
general-purposed I/O with the I/O parameters. [Refer to the instruction manual for the XSEL-R/S/RX/SX/
RXD/SXD controller or XSEL-RA/SA/RAX/SAX/RAXD/SAXD controller for more information.]

Note The number of standard I/O ports is;
• Input 000 to 299 (MAX 300 points)
• Output 300 to 599 (MAX 300 points)
Be careful of the number of I/O ports when using DeviceNet and PIO together.
