Quality of service
In order to enhance the data traffic from the WirelessHART radio to the network the Quality of
Service (QoS) option has been included in the Ethernet Protocol page to allow selection of a
specific traffic control mechanism based on the various manners increase network performance
within a more comprehensive network. There are twenty-one options to choose from
(drop-down menu) as listed and described below, these are the Differentiated Services Cope
Point (DSCP) codes as a standard embedded into network messages IP header:
Default: no specific traffic prioritization is selected
Assured forwarding (AF): this mechanism allows the data traffic to be prioritized based
on the required throughput, delay, jitter, loss or latency following an assured
forwarding per hop behavior. There are four AF Classes and each class has three drop
probabilities which are identified on the bits assignment at the IP header (first 6 bits
within Differentiated Services field)
Drop Class 1 Class 2 Class 3 Class 4
Low AF 11 AF 21 AF 31 AF 41
Medium AF 12 AF22 AF 32 AF 42
High AF13 AF 23 AF 33 AF 43

Class selector (CS): this mechanism allows for a selection of seven options which
prioritizes the data packets as per the option bits within the Type of Service (ToS) byte.
The combination of all three IP Precedence bits is used to adjust the IP packet
prioritization within the network.
Expedited forwarding: this mechanism is used when the data traffic is targeted to have
low delay, low jitter, low loss and low latency, hence prioritizing bandwidth to target a
“point-to-point” communication experience.
The recommended differentiated services setup are: AF41 (Assured Forwarding 41) or EF
(Expedited Forwarding). The AF41 shall be used whenever video related data is part of the
wireless solution and EF shall be used for any other solution which doesn't include video as part
of the package.
1.3.3 System backup

3.1 Overview
This section describes how to connect the Gateway to a host system and integrate data
gathered from the field device network. It covers network architectures, security, and data
mapping.
In accordance with Emerson WirelessHART®security guidelines, the Emerson Gateway should
be connected to the host system via a LAN (Local Area Network) and not a WAN (Wide Area
Network).
3.2 Network architecture
Physical connection types are important when determining the network architecture and what
protocols can be used for integration. Ethernet is the main physical connection type. Emerson
provides all support to design, scope and commission the Smart Wireless Gateway 1552WU
into various types of hosts, please contact us for further information on this topic.
Ethernet
An Ethernet connection supports Modbus®TCP, OPC™, AMS®Wireless Configurator,
EtherNet/IP™, and HART®TCP protocols. Using this connection type, the Gateway is connected
directly to a control network using a network switch, router, or even via a wireless backhaul.
Often there are two networks for redundancy purposes.
3.3 Internal firewall
The Gateway supports an internal firewall that inspects both incoming and outgoing data
packets. TCP ports for communication protocols are user configurable, including user specified
port numbers and the ability to disable ports.
The Gateway’s internal firewall settings can be found by navigating to System Settings>

3.4 Modbus
The Gateway supports Modbus TCP over Ethernet. It functions as a sub device on the Modbus
network and must be polled by a Modbus master or client (host system).

It is important that the Modbus communication settings in the Gateway match the setting in
the Modbus master or client. Please refer to host system documentation for more information
on how to configure these settings. The Modbus communication settings can be found by
