Hardware Specifications

EtherNet/IP Deterministic Network Integration

The 1715-AENTR is designed for operation within EtherNet/IP deterministic network environments. Its dual-channel architecture supports redundant communication paths between the controller and remote I/O infrastructure. Compatibility with Device Level Ring (DLR) topology permits network fault tolerance through alternate communication paths. Within the 1715 Redundant I/O platform, the adapter functions as the communication interface between the backplane and Ethernet network while maintaining synchronization across installed I/O modules.

Frequently Asked Questions

Q: Does the 1715-AENTR support redundant network communication?
A: Yes. The adapter provides two communication channels and is intended for redundant I/O applications using supported EtherNet/IP network topologies.

Q: What power input is required for operation?
A: The module operates from an 18-30 V DC power source and draws up to 380 mA during operation.

Q: Can the adapter be installed without a base assembly?
A: No. The provided specifications indicate that the communication adapter requires a 1715-A2A base assembly for installation and operation.

Field Installation Guidelines

• Mount the adapter on a properly grounded DIN rail according to cabinet installation practices.

• Verify compatibility between the installed base unit and the required 1715-A2A mounting assembly before energization.

• Route Ethernet cables separately from high-voltage power conductors to reduce conducted and radiated noise.

• Maintain shield continuity where shielded communication cabling is used.

• Confirm available power supply capacity for the adapter current requirement of 380 mA.

• Inspect network topology configuration to ensure DLR or star architecture is correctly implemented before commissioning.

• Perform controller-to-adapter communication verification after installation using platform diagnostic tools.
