Cyber security
This product is designed to be connected, and communicate information and data, via a network interface.
All Totalflow products should be connected to a secure network. It is the customer's sole responsibility to
provide and continuously ensure a secure connection between the product and the customer network or
any other network (as the case may be). The customer shall establish and maintain appropriate measures
(such as, but not limited to, the installation of firewalls, application of authentication measures, encryption
of data, or installation of antivirus programs) to protect this product, the network, its system and
interfaces against any kind of security breaches, unauthorized access, interference, intrusion, leakage
and/or theft of data or information. ABB Inc. and its affiliates are not liable for damages and/or losses
related to such security breaches, any unauthorized access, interference, intrusion, leakage and/or theft
of data or information.
Although ABB provides functionality testing on the products and updates that it releases, the customer
should institute its own testing program for any product updates or other major system updates (to
include, but not limited to, code changes, configuration file changes, third party software updates or
patches, hardware change out) to ensure that the security measures that the customer has implemented
have not been compromised and that system functionality in the customer's environment is as expected.
Malware Prevention
Recommendation: As with any downloaded software, scan ABB embedded software packages using a
malware prevention solution.

equipment can result in a degraded system or process performance leading to serious or life-threatening
injuries. Therefore, compliance with all DANGER, WARNING and NOTICE hazards is required at all times.
DANGER
–Serious damage to health / risk to life. These symbols, and the signal word
"DANGER"
,
indicate imminent danger or electrical hazard. Failure to observe this safety information
result
s in death or severe injury. The text describes the hazard, how to avoid the hazard, and the
result if not followed. The lightnin
g bolt is for electrical danger; the exclamation point is for general
dangers.
DANGER – Serious damage to health / risk to life. This symbol, and the signal word
"DANGER", indicates imminent danger or explosive hazard. Failure to observe this safety
information results in death or severe injury. The text states the hazard, how to avoid the hazard,
and the result if not followed.

WARNING
– Bodily injury. These symbols, and the signal word "WARNING", indicate a
potentially dangerous situation. Failure to observe this safety information could result in death or
severe injury. The text may state the hazard, how to avoid the hazard, and the result if not
followed. The bolt is for electrical warnings; the
exclamation point is for general warnings.
NOTICE
– Equipment damage, cybersecurity risk, or loss of data. This symbol indicates a

of data or another unintended outcome. Failure to observe
this information may result in damage to or destruction of the product and / or other system
components.
IMPORTANT NOTE:
This symbol indicates operator tips, particularly useful information, or
important
information about the product or its further uses.
Potential safety hazards
The XIO uses voltages in the range of 12 - 24 Vdc plus some percent of tolerance. There are no hazardous
voltages present in the device. However, some optional power sources might convert power from Vac to -
Vdc.
Pressurized natural gas is present in the measurement pipeline. Natural gas can escape from the pipeline
during installation, calibration, or following damage to the pipeline. Only properly trained and authorized
personnel should work in hazardous locations.
WARNING – Bodily injury. Apply power only after the procedures are complete. Technicians
must perform the procedures in order: plan, install, wire, verify the power-on sequence, and
configure.
WARNING – Bodily injury. The device can be operated at high levels of pressure and with
aggressive media. Serious injury and/or considerable material damage can be caused if this
device is handled incorrectly.
WARNING – Bodily injury. Read and follow instructions contained in this guide before and
during equipment installation. Failure to do so could result in bodily injury or equipment damage.
WARNING – Bodily injury. Ensure there is no hazardous atmosphere present when performing
maintenance on the unit. Do not separate components when energized. This applies to all

Compliance
Waste Electrical and Electronic Equipment (WEEE)
EU Directive 2012/19/EU
ABB Industrial Automation, Measurement and Analytics is committed to actively protecting the
environment. Do not dispose of WEEE as unsorted municipal waste. Collect WEEE separately. WEEE
management participation is critical to the success of WEEE collection.
Do not mix electrical and electronic equipment with general household waste if it displays the
crossed-out wheeled bin symbol. Dispose of it correctly at a recycling facility to save valuable
resources and prevent potential negative effects on health and the environment. These steps
ensure compliance with the Waste Electrical and Electronic Equipment (WEEE) Directive.
Treat waste electrical and electronic equipment (WEEE) separately. Use the national collection framework
available to customers for the return, recycling, and treatment of WEEE.

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.
XIO COM LEDs
There are two kinds of COM LED on the front of the XIO device.

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 has two types of Ethernet ports (A Network and B Network). The A Network ports are Enterprise
Network ports and B Network ports are Industrial Network Ports. Ta b l e 2 -2 shows the uses of the Ethernet
ports.

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 ports 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: 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:

2.2.3 Power port
The XIO has a single port for connection to an external power source. The port supports reverse polarity
protection.
Table 2-3: Power connector specifications
Port
Terminal type
Power
Removable terminal connector (4 POS), spring cage termination. Wire gauge 12 AWG to 22 AWG
IMPORTANT NOTE:
Select wire gauges based on the voltage and current requirements of the
circuitry
and the expected length of the wires. The gauge differs for each application.
The external power supply is the sole source of power to the XIO. The power supply may be one of several
different devices, represented as a rectangle in the following drawing.
