In "ControlNet Specifications, Release 2.0, Errata 2". Part 10 has the "ControlNet Object Library", of which the "Identity Object", class code 0x01, is the first one, attribute 7 of which being a SHORT_STRING product name, and table 10.3 gives its semantics, from which I copied.
How does one get a copy of the specifications? Good question.
At one point, one could go to www.odva.org and download it.
Then, one had to pay for it.
I happened to get a copy on CD-ROM from a colleague at LANL
who originally looked at ControlLogix IOCs for the SNS
project, and he had attended a seminar about the introduction
of ControlNet-Over-Ethernet, as it was called at the time,
where attendees got the CD.
Those specs mention the EtherNet encapsulation of ControlNet
only in an appendix.
It was then renamed into "EtherNet/IP" (for "Industrial Protocol"),
and that's what you now see on the odva web page.
Looks like that right now they offer a paid subscription to the specifications,
no free download,
and 'CIP' has again been renamed, this time from "Control and Information Protocol"
to "Common Industrial Protocol".
