The Allen-Bradley 1715-AENTR, also cataloged as the 1715-AENTR Communication Adapter, operates as a dedicated hardware component for network interface execution within Allen-Bradley 1715 Redundant I/O platforms.
The 1715-AENTR network interface module connects 1715 redundant I/O backplanes directly to EtherNet/IP deterministic networks, coordinating continuous packet transfers over dual-channel media. Supporting Device Level Ring (DLR) and star network topologies, the adapter maintains fault-tolerant network execution and backplane bus communication velocity across linked ControlLogix platforms. Built-in diagnostic capabilities and plug-and-play parameter synchronization support high I/O density scaling without degrading network scan cycle times.
Frequently Asked Questions
Q: What network topologies are supported by the dual-channel 1715-AENTR adapter?
A: The module features 2 EtherNet/IP ports supporting both fault-tolerant Device Level Ring (DLR) and standard star network topologies.
Q: What is the current draw and operating voltage requirement for the 1715-AENTR?
A: The adapter operates on an external supply voltage of 18 to 30 VDC with a nominal current draw of 380 mA.
Field Installation Guidelines
Mount the 1715-AENTR adapter on a standard DIN rail inside an enclosure, ensuring proper clip engagement for structural stability.
Connect the main 24 VDC power feed to the supply terminals, keeping input voltage strictly within the 18 to 30 VDC range.
Attach EtherNet/IP cables to both channels when configuring Device Level Ring (DLR) topology to preserve network redundancy paths.
Ensure continuous low-impedance grounding of the DIN rail to suppress electro-magnetic interference across high-speed network channels.
