Ethernet/IP
EtherNet/IP is based on the control and information protocol (CIP) which is also the framework for
DeviceNet and ControlNet to carry and exchange data between nodes.
Implemented Objects
EtherNet/IP requires some mandatory objects; these are implemented as well as some vendor specific
objects. The mandatory objects are the ones in the specification from ODVA.
The following vendor specific objects are implemented:
• I/O data input mapping object, Class A0h
• I/O data output mapping object, Class A1h
• Diagnostic object, Class AAh
Assembly Object, Class 04h
Description
The assembly object binds all mapped I/O data. This data is used for I/O connections. Default I/O
instances used are 64h and 96h.
