Hello,
I am looking at integrating a couple of devices that support EtherNET/IP and
I am wondering if you could point me in the
right direction.
1. Do you have any go-to whitepapers that lay out the EtherNET/IP protocol?
2. If I have the device's EDS file, what is needed from that to communicate
with a device? (or is it parsed when you
start the connection?)
Thank you for your time

Hi Joe,
There are a number of roles in E/IP: scanner and adapter are two.
Typically the device you want to interface with in the plant, if they are not
PLCs, are going to play the *adapter*
role. That means you have to perform the *scanner* role.
CIPster was used to write a scanner in my company's product: SoftPLC Runtime.
This took a long time and that
additional code was not released as open source. It is layered on top of
CIPster however. It provides a text
configuration file parser and runs in the same process as our softplc runtime.
All the E/IP specifications are copyright ODVA. Generally you join ODVA, get a
vendor ID, and they send you to a
downloaded archive of copyrighted PDF files. Those files are water-marked with
the licensee's name in them. Then you
spend about a half year making sense of them.
I actually think you should talk to our sales department about using our
SoftPLC runtime to get you up and in the
factory as fast as possible. We offer a nice linux hardware solution that you
could put in operation quite soon:
Smart4. It may also be possible to run one of your processes on the box in
addition to our runtime. It comes with a
5.2 linux kernel with a debian bullseye root file system and arch = arm64. We
offer a C++ toolkit for that combination
at no charge.
Please call our sales department at 1-800-SoftPLC to get up and running
fastest. Time to market is usually under-rated
in importance, as is the cost of development.
We've been in factories for 37 years and are likely to be quite helpful to you.
HTH,
Dick Hollenbeck
