EtherNet/IP(TM) is an industrial Ethernet network that combines standard Ethernet technologies with the media-independent Common Industrial Protocol or "CIP." EtherNet/IP is one of the leading industrial Ethernet networks in the world and is widely used in a range from industries including factory, hybrid and process. The EtherNet/IP and CIP technologies are managed by ODVA, Inc., a global trade and standards development organization founded in 1995 whose over 300 corporate members are the world leading automation device suppliers. [Source: Wikipedia] The Common Industrial Protocol (CIP) is an industrial protocol for industrial automation applications. It is supported by ODVA. [Source: Wikipedia] Here OpENer was used for the EtherNet/IP stack. This example based on my previous one with lwIP and MicroHTTP. For the OpENer test the following board was used:
The software use the following key components:
For the compiler, CrossWorks for ARM v2.3.5 was used. The project with my source can be found under the download section. OpENer is an EtherNet/IP stack for I/O adapter devices. It supports multiple I/O and explicit connections and includes objects and services for making EtherNet/IP compliant products as defined in the ODVA specification. Note: In order to create an EtherNet/IP compatible device you will need to execute and comply with the ODVA Terms of Usage Agreement. For more information about becoming an EtherNet/IP vendor take a look at the ODVA page. You do not need to ask. I can not provide the EtherNet/IP specification. You will get these only from the ODVA organization. Credits goes to Alois Zoitl of fortiss and Martin Melik-Merkumians from the Automation and Control Institute (ACIN) of the Vienna University of Technology who have supported me.
