ControlLogix Enhanced Redundancy System | |
The ControlLogix controller supports redundancy. Redundancy enables higher productivity by providing higher system availability by switching control to a secondary controller chassis if the primary redundancy module detects an event on any module in the primary chassis.
ControlLogix firmware version 19.50 provides enhanced redundancy for high-availability applications. See the Rockwell Automation Support site for details on downloading the firmware bundle (V19.52Enh). ControlLogix Redundancy v19.50 adds support for:
- ControlLogix L7 controllers
- ControlLogix Redundancy module, 1756-RM Series B
- Ethernet/IP I/O in a ControlLogix redundancy system
- EtherNet/IP Ring (DLR) topology
- Alarms and Events support for redundant HMIs
- Microsoft Windows 7 Operating System
- Partial import online
- Advanced process instructions
- High-integrity Add On Instructions
- CIP Sync controller support
- Public/Private data
Benefits
- Higher performance through ControlLogix L7 controllers and the 1756-RM series B redundancy module
- Common network backbone with EtherNet/IP network support
- High availability networks with DLR (Device Level Ring) topology
- Alarms and Events support in redundant HMIs through FactoryTalk View 6.0

Example Configuration—ControlLogix Enhanced Redundancy System
Note that this example shows I/O control on both EtherNet/IP and ControlNet networks. Either one or the other is required; you do not need both.
