1 System Description
The ABB XIO is a microprocessor-based device with built-in, pre-engineered applications for expanding
communication and IO over Ethernet to a host controller. The devices are extendable, supporting
hardware expansion using TFIO modules.
XIO may be placed remotely from the controller (RTU) using Ethernet. Configuration of the device may be
performed using USB, Wi-Fi, Bluetooth, or an Ethernet connection. It has extendable IOs, using TFIO
modules and up to 8 onboard COM serial ports to communicate with measurement transmitters, additional
automation or control equipment, flow computers, etc.
1.1 Models
The table below lists XIO models and the number of COM ports available. They are engineered to be
flexible, enable increased productivity, and improve asset use.

1.2 Features Overview
The XIO provides backward-compatible functionality based on ABB Totalflow software, communications,
and IO technologies.
The XIO supports:
– IO and serial communication expansion
– A single, backward-compatible TFIO bus, with the IO module capacity up to 22 modules
For general specifications, refer to the Data sheet on the Remote modular
product page.
