3 Introduction

The KUNBUS TAP CURIOUS is your network monitor for analyzing all standard industrial Ethernet solutions. Four probe ports allow you to capture up to two independent realtime Ethernet connections.
You can use filters to reduce data volumes or select specific analysis data. You can configure these filters via an integrated web server. The web server can operate in 2 different modes. "Basic" mode helps you set your filters and configure your device. "Expert" mode was developed for people with expert knowledge of frame filters. In this mode, you can filter a frame by all the aspects it contains.
The digital input and output allows you to create useful trigger conditions. These can systematically help limit sporadic effects, and identify and remedy the causes.
An internal throughput delay of 0µs (zero delay) makes TAP CURIOUS almost transparent for the data channels to be checked.
TAP CURIOUS is connected to a PC via a standard Ethernet interface. You can operate TAP CURIOUS in 1 Gbit/s or 100 Mbit/s mode. Captured packet data is read and analyzed using network monitors such as "Wireshark", the freely available network analysis software.

4.3 Uplink interface

You can connect TAP CURIOUS to your PC via the uplink interface.
To do this, you need an Ethernet cable with standard RJ45 plugs.
If your PC does not have a free RJ45 port, you can use a USB adapter.

4.4 Test inputs

TAP CURIOUS has 2 communication channels for monitoring the lines. Each of the ports Con 1 and Con 2, as well as Con 3 and Con 4, are connected directly to a communication channel.
You can connect the ports to a device via an Ethernet cable with standard RJ45 plugs.
Overview

5 Application examples

TAP CURIOUS is able to monitor devices in various ways. 2 examples are shown here.
Example 1:
Connect your devices as shown to capture the communication between two devices. This allows you to find faulty frames on the network.
Application examples
Example 2:
Connect your devices as shown to monitor the frames before and after a device throughput. In this example, device 2 is monitored. Here, you could analyze the following:
– Measure the device throughput time,
– Check whether frames have been distorted or truncated,
– Measure jitter on cyclical frames.

6 Starting TAP for the first time

◦ Unpack the device and make sure you have all the components listed in the
scope of delivery.
◦ Connect the device to the power pack supplied.
ð The POWER LED lights up.
◦ Load the "Wireshark" network analysis software onto the PC and install it. You
can download Wireshark from www.wireshark.org.
◦ Download the Wireshark plugin.DLL from the KUNBUS website and copy the
DLL file into the Wireshark plugin folder (e.g.: C:\Programs\Wireshark\plugins \1.10.2). Download the correct DLL file for either the 32 or the 64-bit Wireshark version, depending on which one you use:
- 32-bit version: tap32_1xxx.dll (Wireshark-Plugin WIN32)
- 32-bit version: tap32_2xxx.dll (Wireshark plugin WIN32)
- 64-bit version: tap64_1xxx.dll (Wireshark plugin WIN64)
- 64-bit version: tap64_2xxx.dll (Wireshark plugin WIN64) xxxx denotes the version used (e.g. 1.10.2)
◦ Connect TAP CURIOUS to an Ethernet interface on the PC using a RJ45
cable. Die "Link" LED lights up as as soon as the PC and TAP CURIOUS are connected.
◦ Connect the line to be tested to one of the probe ports. Each of the ports "Con
A" and "Con B" and ports "Con C" and "Con D" are connected directly. So communication is possible even when TAP is deactivated. The "Speed" LEDs show the connection speed set for the probe ports. When frames are being transmitted on the line, the "Activity" LED flashes green.
◦ Start Wireshark on the PC and activate the "TAP" plugin in the menu at "Edit >
Preferences > Protocols > TAP".
Starting TAP for the first time
Illustration6: Wireshark plugin
◦ All available Ethernet interfaces are listed in the main window. Click on the
Ethernet interface you require to select it.
◦ Set any filters you want via the web server. This allows you to search for
specific frames and prevents your PC's main memory from becoming overloaded.
ð You can now use Wireshark to analyze the data.
DO0281R00 17 / 58
TAP CURIOUS expands the Ethernet packets by 20 bytes of additional information. You can use TAP CURIOUS without the plugin or with a different Ethernet analysis program. But you will not be able to analyze this additional information. You might also find that the analysis program reports a data packet as faulty due to this additional information.
Information on the additional data can be found in the chapter called "Monitoring the interface [}51]".
