1 Product overview
The ABB XIO is a microprocessor-based device with built-in, pre-engineered applications for expanding
serial communication and IO over Ethernet to a host controller. The devices are extendable, supporting
hardware expansion using TFIO modules.
The XIO may be located remotely from the controller (RTU) using Ethernet for communication.
Configuration of the device may be performed using USB, Wi-Fi, Bluetooth, or an Ethernet connection
depending on the XIO model. It has extendable IOs, using TFIO modules and up to 8 onboard COM serial
ports (depending on the model) to communicate with measurement transmitters, additional automation or
control equipment, flow computers, etc.
There are 3 models of the XIO based on the number of serial communication interfaces they support.
Figure 1-1 shows the XIO-08 which has 8 COM ports. Figure 1-2
shows the XIO-04 which has 4 COM
ports. Figure 1-3 shows the XIO-00 with no serial COM support (used only for extending IOs).
