2.4 EtherNet/IP
2.4.1 General
EtherNet/IP is based on the Control and Information Protocol (CIP), which is also the application layer
for DeviceNet and ControlNet. The Anybus Communicator acts as a Group 2 or 3 server on the
EtherNet/IP network.
Input and output data is accessed using I/O connections or explicit messages towards the assembly ob-
ject and the parameter input/output mapping objects.

2.4.2 Data Types
The input and output data hold two types of data; I/O data and parameter data. I/O data is exchanged
on change of value, and can be accessed using I/O connections towards the assembly object.
Parameter data can be accessed acyclically via the parameter input and output mapping objects. Note,
however, that each instance attribute within these objects must be created manually using the Anybus
Configuration Manager.
For more information see “Parameter Data Initialization (Explicit Data)” on page 119.
