Statement of Conformance (STC)

The goal of this section is to explain the relation the Anybus Objects to the Conformance Test
and the Statement of Conformance (STC). The objects listed below exist in the host application,
the Anybus CompactCom, and not in the EtherNet/IP interface. The objects are described in
the Anybus CompactCom 40 Software Design Guide and in the Anybus CompactCom 40 Ether-
Net/IP Network Guide.
It is recommended to read the CIP Protocol Test Specification and the EtherNet/IP Test Specifi-
cation prior to testing. In these documents the expected response and/or the acceptable behav-
ior are stated, which is useful to be able to avoid a lot of initial errors. Modifications can be
made to the Statement of Conformance and to the host application at an early stage, reducing
time and effort.
F.3.1 Implementation of Host Objects
The implementations of the host objects may have to be adapted, to make sure that the end
product will pass a conformance test. Using the CT Software, follow the instructions below. Only
the host objects relevant to EtherNet/IP will be discussed.
EtherNet/IP Host Object (F8h)
The implementation of the EtherNet/IP Host Object (F8h) has impact on the following objects:
Identity Object (01h, CIP object), Assembly Object (04h, CIP object), Port Object (F4h, CIP ob-
ject), and CIP Port Configuration Object (host object, 0Dh). It also has impact on how the STC
is configured. The instance attributes, listed below, need to be considered.
EtherNet/IP Host Object (F8h) - Attribute #1 - Vendor ID
The Vendor ID must match the Vendor name in the CT software and the STC.
Fig. 6
First time EtherNet/IP vendors may not find their name available from the drop down menu, as
it's not certain that the test software has been updated. It is possible to pre-test with any Vendor
ID in the list, to reduce the number of errors reported due to Vendor ID mismatch, as long as the
Vendor ID is changed in both the device and in the STC before actual conformance testing.
Alternatively, vendors can add the vendor information to the VID.dat file.

This document is not a comprehensive guide. Following the steps below will not
absolutely guarantee that a device will complete conformance testing.
