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 BridgeWay 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. The BridgeWay supports Message Server and Message Client function-
ality. 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. The
BridgeWay contains the same objects as other modules that are based on the CIP
protocol.
