Common Industrial Protocol 

(CIP) CIP™ is a messaging protocol for devices in industrial automation control systems. 

CIP is the application layer for the EtherNet/IP network. 

This protocol implements a relative path to send a message from the producing modules in a system to the consuming modules. 

CIP uses the Producer/Consumer networking model instead of a source/ destination (Primary/Secondary) model. 

The Producer/Consumer model reduces network traffic and increases speed of transmission. 

In traditional I/O systems, controllers poll input modules to obtain their input status. 

In the CIP system, digital input modules are not polled by a controller. 

Instead, they produce their data either upon a change of state (COS) or at a requested packet interval (RPI).

The frequency of update depends upon the options that are chosen during configuration and where on the network the input module resides. 

The input module, therefore, is a producer of input data and the controller is a consumer of the data. 

The controller can also produce data for other controllers to consume.

The produced and consumed data is accessible by multiple controllers over the Logix backplane and over the EtherNet/IP network. 

This data exchange conforms to the Producer/Consumer model.

These faults and warnings can be cleared with a clear faults command. 

You may have to perform a reset after power-up, or perform multiple resets.

Local DH+ Messaging Devices use local DH+ messaging to communicate between devices on the same physical link.

A device that uses local DH+ messaging must: 

• generate local DH+ packets. 

• support local DH+ protocol. 

• send and receive messages. 

A local DH+ message sent on a DH+ network has only enough address information to get the message 

to a target node on the same DH+ network.
