2.6 I/O Port Numbers for X-SEL
The table below lists the standard I/O port numbers for X-SEL controllers.
On X-SEL controllers, port numbers and function assignments can be changed using I/O parameters. (For
details, refer to the “Operation Manual for X-SEL Controller.”)

(Note) The numbers of I/O ports are as follows:
If DeviceNet and expansion I/O boards are used together, pay attention to the numbers of I/O
ports.
Inputs: 000 to 299 (maximum of 300 points)
Outputs: 300 to 599 (maximum of 300 points)
Reference
When bit addresses are set in the PLC, port numbers are assigned in units of 16 points,
starting from the channels corresponding to the node address set by the parameters.
(This does not apply when a configurator is used.)

The numbers under (NN)/(MM) CH are PLC channel addresses corresponding to node address nn.
Since node addresses (nn, nn+1, nn+2, and so on) are occupied in accordance with the numbers of
input/output points used, pay attention to prevent duplicate node addresses.
