Hello,
Has anyone ported Ethernet/IP protocol onto a netburner module? I see (see below) that there is an open source version of Ethernet/IP available. I myself dont have the competency in ethernet software to do such a port.
For this reason, I think my company will buy a commercially available implementation from RTA.

The Automation and Control Institute (ACIN) of the Vienna University of Technology announces the release of an Open Source EtherNet/IP Adapter Stack. The new license and royalty-free adapter stack is available for download for free through SourceForge.net ((http://opener.sourceforge.net).
"The stack's small footprint, modularity and flexibility make it both a time and cost-saving solution for product developers seeking a standard EtherNet/IP communication stack for industrial products," says Alois Zoitl, director of research, Odo Struger Laboratory, Vienna University of Technology.
The EtherNet/IP open-source stack includes all basic objects required by the CIP (Common Industrial Protocol) specification and allows for the addition of other optional or vendor-specific CIP objects that further expand a product's functionality. The stack supports both explicit messaging (server) capability and implicit I/O (adapter) target connections, including connected and unconnected explicit messaging, and cyclic I/O messaging across unicast and multicast CIP I/O connections.
Rockwell Automation sponsored Vienna University of Technology in the development and release of the free, open-source EtherNet/IP software stack for I/O adapter devices. "The availability of this open-source stack demonstrates the openness of EtherNet/IP and makes network connectivity more accessible to a greater variety of product developers, all working to solve the contemporary needs of today's customers," said Kenwood Hall, vice president of Architecture and Systems Development, Rockwell Automation.

Re: Ethernet/IP protocol software
well, you got me!
The core functionality provided by netburner *is* Ethernet/IP.
So what are you Really asking/discussing?

Real Programmers don't comment their code. If it was hard to write, it should be hard to understand
Re: Ethernet/IP protocol software
Chris,
I think you are confusing the Ethernet functionality offered by Netburner with hte industrial protocol. This is what I am referring to; Wikipedia's definition
EtherNet/IP (Ethernet Industrial Protocol) is an open communications protocol developed by Rockwell Automation, managed by ODVA and designed for use in process control and other industrial automation applications. EtherNet/IP is an application layer protocol and it considers all the devices on the network as a series of "objects". EtherNet/IP is built on the widely used (CIP), which makes seamless access to objects from controlNet and DeviceNet networks.
EtherNet/IP makes use of existing network infrastructure (Ethernet) and the entire EtherNet/IP stack can be implemented in software on a microprocessor. No special hardware such as (Application Specific Integrated Circuits) or (Field Programmable Gate Arrays) are required for implementing EtherNet/IP.
