Frontline's NetDecoder™ protocol analyzer, an award winning
software, is designed to diagnose and troubleshoot communication
problems in industrial networks. Frontline's NetDecoder analyzer has
the ability to monitor and provide detailed timing, data and
messaging information for serial, fieldbus, and Ethernet networks.
The NetDecoder protocol analyzer is used in many industries
including Oil & Gas, Food and beverage, Electric power transmission,
Water or sewer management, and Factory automation.

to learn how the NetDecoder analyzer helps customers.
The NetDecoder analyzer is more than an efficient and effective
troubleshooting tool. It has transitioned into an effective
monitoring tool giving you the ability to see issues developing
before they result in major problems.
Some of the main features of
the NetDecoder analyzer include:
The NetDecoder analyzer also provides the ability to analyze both serial and
Ethernet traffic at the same time. This feature is very handy to
troubleshoot issues where serial to Ethernet converters are used.
The NetDecoder analyzer provides a view to traffic on both sides of the converter
with the NetDecoder analyzer's ability to run both its serial and Ethernet
analyzers at the same time.

The NetDecoder analyzer is an indispensable test,
measurement and monitoring tool for:
The Statistics display window includes information that is relevant for
all networks. This information includes:
from the above common information, NetDecoder also gathers data specific to
the properties of the industrial network being monitored. Some examples of
this include statistics for Ethernet,
ControlNet, DeviceNet and
The statistics dialog for the Ethernet analyzer includes error
information supported by the NDIS drivers. Since not all errors are
supported by all NDIS drivers, the ones not supported are marked "n/a". Some
of the Ethernet errors statistics reported include:
NetDecoder's ControlNet analyzer uses the 1784-U2CN or the 1784-PCC card
as the sniffer interface. The interface cards are designed around the
ControlNet CNA10 ASIC. The ControlNet analyzer gathers information about
frames dropped by the CNA10 ASIC. The protocol analyzer also provides the
number of frames that were dropped by the buffer in the 1784-U2CN device.
Other useful ControlNet related error information includes the number of bad
frames received and the MAC IDs of nodes transmitting bad frames. The
ControlNet analyzer maintains a list of the last eight MAC IDs that
transmitted bad frames.
NetDecoder's DataHighway-Plus analyzer includes a special "Dashboard
View". This presents statistics on:
Another unique feature of NetDecoder's Statistics display is multiple
tabs on the Statistics dialog. All the screenshots above show three tabs in
the dialog. These tabs are named "Session", "Resettable" and "Capture File".
Information about all data collected since the analyzer was started is
shown in the Session tab. The Session tab cannot be reset; in this sense, it
is like the odometer on a car. The odometer on a car shows you all the miles
driven since the car was built, and the Session tab shows you all the data
collected since the analyzer was started.
If you think of the Session tab as the odometer, then the Resettable tab
is the trip odometer. It can be reset, and allows you to record statistics
for a new "trip". In this way you can effectively start a new session
without having to restart the analyzer.
The Capture File tab shows information on the data that is currently in
the capture. Occasionally some of the statistics read n/a, for Not
Available. This happens for various reasons. For example, many of the items
on the Capture File tab become not available (n/a) if the buffer becomes
full and wraps. When this happens, the analyzer can no longer provide
accurate statistics for the data in the file, because some of the data that
the statistics are based on has been lost.
NetDecoder's Network View feature provides an additional tool to easily
debug network communication problems. Along with the Dashboard feature, the
Network View forms a suite of graphical tools that provide an
easy-to-comprehend visual display of the network. It can also be used to
identify and fix problems before they can cause too much trouble on the
network. The graphical features make NetDecoder an extremely powerful
network analyzer and troubleshooting tool. The Network view is currently
available for Ethernet and ControlNet networks.
Ethernet Network View
NetDecoder's ControlNet analyzer based on the 1784-PCC
card, provides a Network View display. This view provides a complete
grid-layout of all the nodes. The layout reflects the status of RSWho
status inquiry of the network. This display is consistent with the
feature provided by Rockwell Automation's ControlNet traffic analyzer.
Active nodes are highlighted in green and non-existing nodes are shown
in grey. Nodes that drop off the network instantly turn from green to
grey indicating a problem. This change in device status points the
network administrator in the direction of the problem. Apart from, the
network layout, the ControlNet network view also provides statistics on:
The ControlNet analyzer also provides the used and available
scheduled and unscheduled bandwidth information. This information is
very useful for troubleshooting problems on a ControlNet network.
NetDecoder can be used effectively to detect communication problems at an
early stage. This reduces network downtime and saves network operators a lot
of money. In order to detect communication problems easily, NetDecoder's
analyzers include the Dashboard feature. This dashboard shows the live
status of the network in an easy-to-comprehend graphical display. The
dashboard highlights the key aspects of the network that contribute to the
overall system health. The dashboard is customizable and also includes
alarming capabilities. The dashboard is available for Ethernet and

This display can be used to analyze industrial control networks such as
Ethernet/IP, ModBus/TCP, PROFINET, DNP3 over
Ethernet, CSP and PCCC over Ethernet. The display can also be used for
all general Ethernet communications traffic. The Ethernet Dashboard View
provides a graphical insight into the dynamics of the Ethernet network.

This display enables you to see the health and dynamics of what is occurring
on your Data Highway Plus network. Periodically monitor your DH+ network
with NetDecoder to stay on top of developing situations that could cause
performance or network problems. NetDecoder is a passive monitor and does
not contribute to network loading.
