Integrated Architecture capabilities expanded with ControlLogix redundancy

Establish Redundancy Without Additional Programming With ControlLogix redundancy, you can establish redundancy between a pair of controller chassis without any additional programming. ControlLogix redundancy is designed to be viewed as a single system and will be transparent to any devices connected over a ControlNet or EtherNet/IP network.

The primary controller chassis automatically determines what data changes during its scan and automatically sends that data to the secondary controller to keep it ready to immediately take over control without any change in the outputs. You do not need to program messages nor specify certain data to transfer. This feature eliminates the need to spend valuable engineering resources setting up the redundancy system.

Version 19.50 provides support for:

EtherNet/IP™ I/O
Device Level Ring, star and other EtherNet/IP topologies providing a variety of fault-tolerant networks that provide scalable resiliency to meet all network availability, cost and performance requirements.

Partial Import Online
Make larger runtime changes to applications than possible in the past, for example, adding new programs and/or routines. You can make these changes offline and then download to the controller without stopping it.

Part of a Complete High Availability Solution
ControlLogix V19.50 firmware provides a foundation for a complete end-to-end high availability solution that helps to protect production and product quality, critical equipment and plant assets, plant personnel, the environment and surrounding community. The following products work with ControlLogix redundancy V19.50 to make the solution complete.

ControlLogix L7x Controllers
The L7x controllers offer significant improvements in performance over the ControlLogix L6x controllers when you use them with 1756-RM series B redundancy modules.

1715 Redundant I/O with Redundant Ethernet Adapters
1715 fault-tolerant I/O provides redundant input and output modules including analog outputs configured by RSLogix 5000 and supporting redundant Ethernet adapters all with no additional programming required.

FactoryTalk SE View 6.0
FactoryTalk® View 6.0 supports alarm and event server redundancy for auto-synchronization of device-based and tag-based alarms between active and standby servers and a single alarm history configuration.

Features and Benefits

ControlLogix® redundancy can help if you:

• need the ability to maintain the system without stopping the controller
• run continuous processes where downtime can result in equipment damage or expensive restarts
• deal with high volumes of product where downtime would result in significant loss in revenue
• produce expensive product where downtime could result in damage to the product
• control high visibility processes where downtime could cause large-scale public inconvenience.
