Features:
- Single Ethernet path: one RJ45 interface operates at 10/100 Mbps
- Eight-module station: the adapter supports a local FLEX I/O bank of up to eight modules
- FLEXBus supply: 5 V DC at up to 640 mA powers the local bus
1794-AENT gives an installed FLEX I/O bank a direct EtherNet/IP connection without changing the field-module platform.
Its one-port architecture is a defining boundary when a cell is reviewed for ring resilience or a dual-port replacement.
Station recovery depends on preserving the IP record, rack sequence, module profiles, firmware information, and power calculation.
Rockwell Automation identifies 1794-AENT as end of life; availability is subject to Apter Power sourcing confirmation.

Keep the FLEX I/O station within its adapter limits
- Module count: retain no more than eight I/O modules behind the adapter.
- Bus current: total every module contribution against the 640 mA FLEXBus output.
- Station order: preserve the documented module sequence and electronic profiles.
- Power input: maintain the adapter supply within 19.2...31.2 V DC.
Recover the single-port network record
- Addressing: archive the IP address, subnet, gateway, and naming method.
- Data rate: verify 10/100 Mbps negotiation with the connected switch.
- Connections: document scanner ownership, requested packet intervals, and consumed data.
- Fault baseline: capture link and adapter status before service work begins.
Assess the published functional replacement
- OEM reference: Rockwell Automation lists 1794-AENTR as the functional replacement.
- Topology: decide whether the replacement remains linear or uses both Ethernet ports.
- Engineering files: retain the controller project, EDS/AOP records, and adapter firmware.
- Physical fit: compare depth, connectors, wiring access, and DIN-rail clearance.
Officially supported application roles
- Distributed I/O: connect a local FLEX I/O station to an EtherNet/IP controller.
- Legacy cell service: restore a documented single-port adapter installation.
- Remote machine signals: exchange field I/O data across an industrial Ethernet network.
- Migration projects: establish the installed baseline before moving to the listed successor.
