More Information

Overview Manuals Adapter Capacity Ethernet Configuration Migration Review Product Applications

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.
Description
1794-AENT connects a FLEX I/O station to EtherNet/IP through one 10/100 Mbps RJ45 interface. The adapter supplies the local FLEXBus and supports as many as eight I/O modules in the station.

For installed Ethernet cells, 1794-AENT provides a single network path and operates from a nominal 24 V DC supply. Its 640 mA FLEXBus output must be included when the module sequence and station power budget are checked.

Rockwell Automation identifies 1794-AENT as an end-of-life catalog and lists 1794-AENTR as the functional replacement. Migration planning still needs to account for network topology, adapter configuration, firmware, mounting depth, and the complete I/O rack definition.

Technical notes
The model-specific risk for 1794-AENT is treating the listed successor as an automatic network replacement. Review the existing single-port topology, IP configuration, eight-module station limit, 640 mA FLEXBus budget, adapter firmware, rack sequence, and panel depth before approving a migration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What must be preserved before migrating a station that uses 1794-AENT?
Archive the full rack order, module profiles, IP settings, controller connections, requested packet intervals, firmware record, FLEXBus current calculation, and switch-port configuration.
Why does replacing 1794-AENT with the listed successor still require an engineering review?
The official replacement reference does not establish identical topology, depth, firmware, connection behavior, project support, or commissioning steps for every installed cell.
How can an eight-module station limit affect a proposed expansion behind 1794-AENT?
Count the exact modules and calculate their FLEXBus demand; an available rail position does not override the adapter module count or 640 mA bus limit.
Which checks are useful when 1794-AENT has link indication but no I/O data?
Compare the IP record, scanner ownership, module sequence, connection status, switch negotiation, requested packet interval, controller project, and adapter diagnostic indicators.
How should the 24 V DC supply for 1794-AENT be investigated during intermittent resets?
Measure voltage at the adapter under load, inspect polarity and terminals, review supply dips and grounding, and confirm operation remains inside 19.2...31.2 V DC.
What should incoming inspection verify on a sourced 1794-AENT?
Match the complete catalog and series label, inspect the RJ45 and power terminals, record traceability, and compare physical condition with the approved purchase specification.
