3.2 I/O Ports
The I/O port can deliver the data with the XSEL controller and external signals through
interface.
One port can exchange data for one contact (1 bit).
Data is exchanged via PIOs (24-V I/Os) or over a field network.
Either a PIO or field network can connect to each port at a time.
Whether to use PIO or field network is set by a parameter.
Refer to Chapter 2.3.4 for the I/O interface.
For the field network interface, refer to each instruction manual.
