• allowing HMIs on channel 0 to automatically transfer to the primary processor.

• transfer of up to 2 K words of retentive data per BSN.

• repair of primary system fault during secondary backup system operation.

• remote programming capability of secondary processor on DH+ (SLC 5/04 only).

• minimal user program impact.

• backup system diagnostic information.

Ethernet Network

The TCP/IP Ethernet network is a local-area network designed for the high-speed exchange of information 

between computers and related devices. With its high bandwidth (10 Mbps to 100 Mbps), 

an Ethernet network allows many computers, controllers, and other devices to communicate over vast distances. An Ethernet network

The 1747-BSN module contains the full complement of RIO scanner features, plus

backup capability for support of redundant processor applications. The backup system

consists of one or more pairs of complementary modules, with one module residing in the

primary system and the other in the backup system. The primary system controls the

operation of remote I/O, while the backup system monitors communications via the

high-speed serial link (HSSL) and is available to take control in the event of a fault in the primary system.

Selecting a ControlLogix System

The ControlLogix system architecture provides sequential, process, and

motion control together with communications and state-of-the-art I/O in a

small, cost-competitive package. The system is modular, so you can design,

build, and modify it efficiently - with significant savings in training and engineering.

A ControlLogix system can be anything from a simple chassis to a highly-distributed

system consisting of multiple chassis and networks working together.

A simple ControlLogix system consists of a stand-alone controller and I/O modules in a single chassis.

Or you can use the ControlLogix system as a gateway. Include the

communication modules you need for connectivity to other networks. For

this use, a controller is not required. The ControlLogix Gateway integrates

into existing PLC-based systems so that users with existing networks can

send or receive messages to or from other networks.

For a more robust system, use:

• multiple controllers in a single chassis

• multiple controllers joined across networks

• I/O in multiple platforms that is distributed in many locations and

connected over multiple I/O links

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.
