13 EtherNet/IP™ object classes, messages, and services
The device supports the Common Industrial Protocol (CIP) by using digital input points (DIPs) and digital output points
(DOPs) according to the ODVA specification. EtherNet/IP™ uses the Common Industrial Protocol (CIP) as the application
layer. IP and TCP or UDP are used for the network and transport layers. CIP and EtherNet/IP™ are standardized by the ODVA
on a manufacturer-neutral basis. The Common Industrial Protocol is an object-oriented protocol with two different types of
communication between a controller and termination devices.
The following table describes the two communication types.
13.1 CIP class services
The device supports the following class services and instance services:
13.2 CIP object classes
The device supports the following CIP object classes:
Connection type Description
Explicit messaging This means that a controller or an engineering system sends a request and the termination device
responds.
For example, explicit messaging can be used for configuration and/or diagnostics.
Implicit messaging Implicit messaging is used for the cyclic transmission of I/O data.
That means, for example, that a termination device sends an analog value which is present at a
termination device input. The time for a transmission cycle can be set via the requested packet in-
terval (RPI).
