Bulletin 1715 Redundant I/O System allows a ControlLogix® controller to communicate to remote, redundant I/O via an EtherNet/IP™ network without requiring additional programming or wiring. This system provides fault tolerance and redundancy for critical processes by using a pair of redundant Ethernet adapters and multiple I/O modules. The I/O modules provide diagnostics and are interchangeable with no interruption to the control system.

Features

• Supports several network topologies, including Device Level Ring (DLR) for enhanced network resiliency
• Offers flexible, modular construction for user-configurable I/O applications
• Provides I/O redundancy for system requiring high availability
• Suitable for simplex and duplex connections and fault tolerant applications
• Requires no additional hardware or programming software to operate
• Supports online module removal and replacement with no interruption of the signal inputs
