NetDecoder Users

The NetDecoder analyzer is an indispensable test, measurement and monitoring tool for:

  • Industrial control and SCADA design engineers.
  • OEM development and test engineers.
  • System integrators.
  • Field service and maintenance engineers.
  • Network engineers.
Event Display Window - The captured data includes data bytes, timestamp, control signal states, and line errors. Byte value can be displayed in hex, decimal, octal, binary, and either ASCII, EBCDIC, or Baudot. The software calculates the time difference (Delta time) between selected bytes or events. Users can open multiple Event Display windows to view different segments of the captured data and quickly find byte-oriented errors and timing issues. The Event, Frame and Statistics Displays are all synchronized.

Find Function - Users can search data as it is being captured or after it has been saved. The find function allows users to quickly pinpoint problem areas. Users can find a specific event in the data stream by searching for time (absolute or relative), errors, and signal changes or data patterns.

Breakout Box Window - The software provides a graphical view and real time status of the major RS-232 control signals: DTR, RTS, CTS, DSR, CD, and RI. The software counts and displays the number of control signal state changes.

Signal Display Window - The software provides a graphical view of live control signal transitions and even after they have been saved. The Zoom function allows users to view the state of control signals for a range of events, or changes over a capture session. The "Snap To" feature simplifies problem isolation by causing the cursor to snap to the nearest signal change.

Event Export - Users can export Event level information in to text, Excel, HTML, or binary format. The output is human readable and suitable for importing into a spreadsheet or database, or useable by other programs. Users can select the range of events to export.

Frame Display Window View data at varying levels of granularity, from frame/message level to bit/byte level. Includes summary information for messages sent and received. Decoding of message into text. Protocol errors are identified with red frame numbers. Message is shown in binary, octal, hex and ASCII. Display filters include pre-set filters, node information filters and user defined complex filters. Capture filter limits the amount of Ethernet data captured. Multiple Frame Display Windows can be opened for simultaneous views of different sections of the captured data.

Summary Pane View a one line high-level overview of each data frame/message. Select a protocol layer and the most significant fields are displayed in a concise form. Selecting a specific message frame causes text information to appear in the Frame Decode pane. To facilitate troubleshooting, all panes are adjustable in size and are synchronized. Selecting a message frame in the Summary pane automatically updates the other panes. Selecting an item in the Decode pane highlights the corresponding bits or bytes in the other panes. Protocol errors result in red frame numbers. Quick-filters create a new Summary display that only includes frames/messages that contain the protocol layer you have selected, making it easy to zoom in on your messaging/protocol problems. Frame Summary information can be exported into CSV format and loaded into a spreadsheet or other program to do intricate statistical analysis of protocol and network information.

Find Specific Information in Frames Examine and search data as it is being captured (or after it has been saved), through use of the Find Function. Use the Find Function to quickly pinpoint problem areas in the captured data or to move to a specific frame. The frame level Find Function can 1) search the text of the decode for a specified string, 2) search for errors, and 3) limit the search to DTE or DCE. Data searches can also be performed at the byte level.

Quick Find Features
  • Tab Filters - Display only selected protocol
  • Quick Filter - Preset Filters for displaying error messages, bookmarks, protocols and more
  • Right Click Filter - Display only selected decodeItem in summary pane.
Display Filters Use the Display filters to sift through large volumes of captured data and focus only on the problem areas. FTS’s unique "drill down" capability enables the user to apply new filters while preserving previous views of the data. Filter parameters include protocol and data pattern; advanced mode enables the user to set up complex filters. Display filters can be saved for later use.
Frame Export Outputs frame level information in text. Provides output that is formatted and human readable, suitable for importing into a spreadsheet or database, or useable by other programs for post-processing.
NetDecoder gathers and maintains important statistical information related to the network being monitored. This information is crucial to debug and troubleshoot communication problems on the industrial network.

The Statistics display window includes information that is relevant for all networks. This information includes:

  • Bandwidth Utilization data.
  • Frame rate (Frames/second).
  • Character or Byte rate (bytes/second).
  • Frame/message size distributions.
  • Error information.

Apart 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 DH+.

Ethernet Statistics

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:

  • CRC errors.
  • Alignment errors.
  • Number of received frames with errors.
  • Number of transmitted frames with errors.
  • Number of frames successfully transmitted after detecting one collision.
  • Number of frames successfully transmitted after detecting multiple collisions.
  • Number of frames successfully transmitted after transmission has been deferred at least once.
  • Number of frames not transmitted due to excessive collisions.
  • Number of frames not transmitted due to under-run errors.
  • Number of frames transmitted without detecting the collision detection heartbeat.
  • Number of times carrier sense was lost during frame transmission.
  • Number of collisions detected after the normal window.

ControlNet Statistics

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.

DeviceNet Statistics

NetDecoder supports two options for running the DeviceNet analyzer. Users can choose either Rockwell Automation's 1784-U2DN or SST's DeviceNet interface cards. For both these interfaces, NetDecoder provides statistics on

  • CRC errors.
  • Bit-stuff errors and error flags.
  • Firmware buffer overflows (U2DN or SST interface).
  • Frame errors.

 

DH+ Statistics

NetDecoder's DataHighway-Plus analyzer includes a special "Dashboard View". This presents statistics on:

  • Busy tokens.
  • Total bytes sent.
  • Event log.
  • Token rotations.
  • Top listeners.
  • Top talkers.
  • Top conversations.

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 Ethernet analyzer provides an extensive, customizable Network View display. Ethernet Network View Statistics include:
  • Utilization Information.
  • Packets Transmitted and Received.
  • DNS Names.
  • Nodes In and Out.
  • Broadcast Information.
  • IP Address, MAC Address, Net Bios Name.
  • Ability to enter User Assigned Friendly Names to the nodes.
ControlNet 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:

  • Network Update Time.
  • Max Scheduled Node (Smax).
  • Maximum Unscheduled Node (Umax).
  • Slot time.
  • Blanking Time.
  • Guard Band information.
  • Interval Modulus.

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 DH+ networks.

Ethernet Dashboard Display NetDecoder's Ethernet analyzer includes the Ethernet Dashboard Display 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. NetDecoder is a passive network monitor and does not contribute to network loading.
