Cyber security

This product is designed to be connected to and to
communicate information and data via a digital communication
interface. It is your sole responsibility to provide and
continuously ensure a secure connection between the product
and your network or any other network (as the case may be).
You shall establish and maintain any appropriate measures
(such as but not limited to the application of authentication
measures etc.) to protect the product, the network, its system
and the interface against any kind of security breaches,
unauthorized access, interference, intrusion, leakage and/or
theft of data or information.
ABB Ltd 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.
The AWT420 can handle a data rate up to 300 packets per
second, which far exceeds what the application needs. It is the
customer's responsibility to ensure that the device is deployed
in a network that does not exceed this packet rate. If the device
were to experience data flooding exceeding this rate, it will
become unresponsive to network requests during the data
flooding and, for several seconds after the data flooding ends.

Overview

Ethernet features

Ethernet is the standard way to connect devices on a wired
connection. It provides a simple interface for connecting
multiple devices on a local network (LAN).
The AWT420 supports 10Base-T and 100Base-T using screened
twisted pair (STP) or unscreened twisted pair (UTP) Cat-5e
cable.
The AWT420 Ethernet communication supports the following
TCP/IP protocols/features:
• Web Server both unsecured (HTTP) and secured (HTTPS)
with SSL/TLS encryption and private/public key
authentication
• FTP, both unsecured and secured over SSL/TLS
connections
• Username and password configuration for remote access
to the system using the above protocols
• DHCP (Dynamic Host Configuration Protocol) to
automatically configure the device's IP Address
• DNS (Domain Name System) protocol used to interact with
an Internet name resolution server
Note
The AWT420 supports both secure protocols (HTTPS and SFTP)
and insecure protocols (HTTP and FTP), although insecure
protocols are disabled by default. Insecure protocols transmit
unencrypted data that an attacker who has hacked into the
network can spy and capture. ABB recommends the use of
secure protocols.
