An understanding of Objects, Instances as well as Attributes is key to the understanding of data representation in the Ethernet/IP protocol.

Ethernet/IP data representation is introduced using Modbus as a comparison. An example of a PLC discrete input is used.

There can be one or many object instances of the same object class. An object instance will have many different attributes, and those attributes can be of differing data types.

The assembly object aggregates data from different objects into a single data frame and there by allows for the rapid exchange of data. It is used heavily for I/O communication.

Ethernet/IP is created by implementing the common industrial protocol (CIP) as an application layer on top of Ethernet and TCP/IP.

The Ethernet/IP documentation showing objects/instances/attributes for the ACS drive.

Ethernet/IP uses two types of messaging: Explicit and Implicit messaging.

Explicit Messaging in the Ethernet/IP protocol.

Network commands in Ethernet/IP are known as Services. Each service has a unique code, hence you will here the term service codes.

Implicit Messaging in the Ethernet/IP protocol.
