1Product 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).

DANGER – Serious damage to health / risk to life. Explosion Hazard: Do not connect or
disconnect connectors or their terminations while energized unless the area is known to be non-
hazardous.
The configured interface type and the distance between the XIO and the connected external device
determine maximum serial communication speed. The supported port speed ranges from 2,400 bps to
115,200 bps.

USB port
The USB type mini B port provides high-speed serial communications between the XIO and equipment,
host systems or computers with USB interfaces. The port supports local operator access through PCCU32.
The USB port has two speed modes: full speed and high speed. The XIO automatically negotiates data
transmission rates with the host system.
Ethernet ports
The XIO supports embedded managed Ethernet switch capabilities through its 2-port sets of Ethernet
ports. One set is labeled as A Network and the other as B Network on the device. The A Network ports,
also referred to as Enterprise Network ports, can be used for connections to the corporate wide area
network or for connections to the field network for device management. The B Network ports, also
referred to as Industrial Network ports, can be used for connections carrying real time measurement
traffic. The XIO has the flexibility to support connections as a 4-port Ethernet switch (A Network and B
Network interfaces are combined into a single logical network) or provide separate Ethernet interfaces (A
Networks are separate from B Networks). The XIO also supports port forwarding when not in 4-port
switch mode. All options are configurable from the user interface (PCCU).
Ta b le 2 -2 shows the typical use of the Ethernet ports. All ports can be used for star or daisy-chain
connections. The topology depends on the actual configuration of the interfaces which depends on field
requirements.
Note that all ports can be used for direct local connection by operators and field technicians.

Two physical ports: 1 and 2.
Two possible interfaces labeled: A1 and A2.
Two Ethernet Modes:
–The 1 Network mode provides a single
interface (A1+A2). The XIO behaves like a
2-port switch.
–The 2 Network mode provides two
separate interfaces (A1, A2). Each
interface can be assigned its own network.
B Network
(1, 2)
10/100 Mbps Full Duplex
(Supports auto-negotiation and uses
standard or straight-through Ethernet
cable)
Real-time data communication between XIO
and RMC or other devices.
Two physical ports: B1 and B2.
One Ethernet Mode only: 2 Network mode
provides two separate interfaces (B1, B2). Each
interface can be assigned its own network.

IMPORTANT NOTE:
All ports can be configured for any desired connection based on field
requirements. A Network ports are not restricted to WAN or field LAN connections. B Network ports
are not restricted to local field connections. Configuration of the associated interface
s is flexible.
Ta b le 2

details on
Ethernet connections, refer to section 9 Ethernet connectivity scenarios, or click Help
on
the
Networking tab when connected to the device with the user interface (PCCU32).
2.2.2 TFIO expansion interfaces
The XIO provides two interfaces to add modular I/Os. The XIO supports up to 22 TFIO modules.
The XIO uses an independent bus to communicate with the modules. Totalflow has an I/O protocol to
exchange information between the modules and the XIO. The bus operates in a master/slave mode, with
the main board acting as master.
The TFIO modules are DIN rail mountable and employ contact technology for field wiring. The modules
interconnect to each other to provide the necessary power and interface signals along the bus.
The TFIO modules are hot-pluggable and can be inserted, replaced or removed during the normal
operation of the device with no restart required. The system will detect any changes to the modules on
the TFIO bus and the module states can be verified with PCCU.
DANGER – Serious damage to health / risk to life. Explosion Hazard: Do not connect or
disconnect TFIO modules, connectors or their terminations while energized unless the area is
known to be non-hazardous.
IMPORTANT NOTE:
Power compatibility for TFIO modules depends on module type:
−Older green modules must only use 12 Vdc.
−M2 modules and newer grey modules can use 24 Vdc.
−A combination of green modules, and M2 modules or grey modules, must only use 12 Vdc.
Figure 2-8 shows the location of the XIO TFIO connectors for attachment of the TFIO Modules. All XIOs
and TFIO modules support a male TFIO connector on the left and a female connector on the right (not
visible in the illustration). A TFIO module can be attached to either side of the XIO. The location depends
on the location of the XIO and the space on DIN rails inside an enclosure. See Figure 2-4 which shows an
XIO with two modules attached inside an enclosure.
Figure 2-8: TFIO module connections to XIO
All modules have four LED lights, a manual reset button, and a selectable address from zero through
seven (Figure 2-9). The faceplate of each module shows:
