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.

Universal Remote I/O (RIO) Network 

The strength and versatility of the Universal Remote I/O network comes from the breadth of products it supports. 

In addition to 1746 I/O, the Universal Remote I/O network supports many Allen-Bradley and third-party devices. 

Typical applications range from simple I/O links with controllers and I/O, to links with a wide variety of other types of devices. 

You connect devices through remote I/O adapter modules or built-in remote I/O adapters. 

Using the Universal RIO Network instead of direct-wiring a device over a long distance to a local I/O chassis reduces installation, 

tart-up, and maintenance costs by placing the I/O closer to the sensors and actuators. 

SLC 5/03, 5/04, and 5/05 processors support pass-thru which lets you configure RIO devices remotely from an Ethernet, 

DH+, or DH-485/DF1 network, as well as block transfer instructions for faster reading and writing of I/O data.
