Conformance Test Guide
B.1
General
When using the default settings of all parameters, the Anybus CompactCom B40 Modbus Serial -
EtherNet/IP is precertified for network compliance. This precertification is done to ensure that
the end product
can
be certified.
To be allowed to use EtherNet/IP in a product the vendor is required to be a licensed
EtherNet/IP vendor, with a vendor ID of its own. Please contact
to obtain a
vendor ID.
Changes in the parameters in the example EDS file supplied by HMS Industrial Networks will
require a certification. This chapter provides a guide for successfully conformance testing your
device, featuring the Anybus CompactCom B40 Modbus Serial - EtherNet/IP, in order to comply
with the demands for network certification set by the ODVA.
The actions described in this appendix have to be accounted for in the certification process, e.g.
the identity of the product needs to be changed to match your company and device.
This appendix provides guidelines and examples of what is needed for conformance
testing and certification. Depending on the functionality of your application, there may be
additional steps to take.
All screenshots within this document are taken from the ODVA Conformance Test Software Tool
for EtherNet/IP CT14, © ODVA Inc. This software is available for order through the ODVA website.
It is required to perform pre-testing with this software prior to submitting the product for
conformance testing.
Also, a Statement of Conformance file (STC file), describing the EtherNet/IP application, has to be
prepared prior to submitting the product for conformance testing.

Suggested Test Tools
B.2.1
Wireshark
This free, open source tool is the de facto standard for network capture and analysis. It is heavily
used by ODVA Test Service Providers (TSPs), HMS Industrial Networks, and the greater EtherNet/
IP user base. Wireshark (
) captures Ethernet traffic using your computer’s
network interface card, and displays the contents in an intuitive fashion that allows for detailed
analysis of the packets. Developers from HMS Industrial Networks have contributed to the
EtherNet/IP dissectors (the analysis engine), and it is possible for users to create their own
dissectors for their application data. The use of Wireshark is well documented, but there are a
few good tips for EtherNet/IP testing that will help users filter out the crucial information.
•
Use viewing filters “CIP” to see only EtherNet/IP traffic.
•
It is possible to filter by the HMS MAC ID. This will only show Ethernet messages with HMS
devices as the source or destination “eth.addr[0:3] == 00:30:11”.
•
There are many other useful filters available on the Wireshark webpage.
B.2.2
NMAP
NMAP is a free, open source tool for network discovery and security testing. NMAP will discover
which TCP and UDP ports are open or responding. It will also determine which layer 3 services
are supported by your device. ODVA has strict guidelines for open ports, and mandatory layer 3
services. For the NMAP procedure used by TSPs please see the Sample Test Report that comes
with Conformance Test Software from ODVA.
