The 1715 Redundant I/O System is a remote redundant I/O system that was
developed to communicate with a Logix controller in a ControlLogix®
enhanced redundant system by using the EtherNet/IP network and includes
these components:
• A pair of 1715-AENTR adapters serves as a 'proxy' for all EtherNet/IP
messages to and from redundant I/O modules.
• 1715 digital and analog I/O modules.
• A 1715-A2A dual redundant I/O adapter base unit connects to a
1715-A3IO I/O module base unit to form the backplane for the system.
• Termination assemblies are available in Simplex and Duplex
configuration. They mount onto the 1715-A3IO I/O module base unit, and
connect the I/O modules to the I/O wiring.
• Each 1715-A3IO I/O base unit holds up to three I/O modules. Up to
24 I/O modules can be added to the system.
• The system is built on DIN rails within a cabinet enclosure.
• 1715-C2 expansion cables can be used to allow for space restrictions of the
system within the cabinet.

The general system layout for the 1715 Redundant I/O System consists of the
following hardware components.

1715-AENTR Adapter Redundant Pair

The 1715 adapter communicates via the EtherNet/IP network to a 1756
ControlLogix controller, which conveys system I/O data.
