EtherNet/IP Interface
EtherNet/IP is based on the Control and Information protocol (CIP) which is also
the application layer for DeviceNet to exchange data between nodes.
Product Features
The Anybus-X contains EtherNet/IP Adapter Class functionality. Being an I/O
Server it can respond to requests for I/O messages but it does not generate such
requests. A Scanner device would generate these requests. The Anybus-X sup-
ports Message Server and Message Client, functionality. This means it can act as a
target and originator for messaging.
CIP Objects
CIP makes use of abstract object modeling to describe the communications of a
product. Objects are well defined subsets of a device’s functionality. They have
functions that they perform called Services and data variables called Attributes. If
more than one copy of an object is needed each copy is called an Instance. We
have implemented the same objects as other modules that are based on the CIP
protocol.
