      Information

      Overview Manuals ControlNet Node FLEX I/O Assembly Series Replacement

      Features:

      • Provides ControlNet version 1.5 communication for a compatible FLEX I/O node.
      • Supports a local FLEX I/O group of up to eight modules within the documented power and connection limits.
      • Single-channel ACN15 hardware must not be confused with redundant-media ACNR adapter catalog numbers.

      The 1794-ACN15 bridges a single ControlNet channel to a compatible FLEX I/O terminal-base assembly. It transfers scheduled and unscheduled network data for an installed group of up to eight FLEX I/O modules and provides ControlNet version 1.5 communication for distributed machine or process-control signals. It is the single-channel ACN15 execution and should not be confused with an ACNR redundant-media adapter.

      A working replacement depends on more than the adapter catalog number. The hardware series, 24 V DC power, ControlNet node address, network keeper and schedule, BNC trunk connection, NAP use, terminal bases and exact I/O module order must all be preserved. Series-replacement guidance and lifecycle planning should also be checked before returning a legacy node to service.

      The 1794-ACN15 Allen-Bradley FLEX I/O ControlNet Adapter may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).
      Allen-Bradley 1794-ACN15 documentation and reference links.Important Notice: The linked PDF is an official manufacturer document for this model or its documented exact product family.

Accessories, software and certificates are included only when stated in the written quotation.

      Record the node address, network schedule, keeper, trunk connection and every ControlNet diagnostic indication.

      Confirm the power supply and exact terminal-base and module order, with no more than the documented eight modules.

      Match the complete catalog and series and verify the Rockwell series-replacement guidance before returning the node to the network.

      Technical notes

      1794-ACN15 is a single-channel ControlNet FLEX I/O adapter. Preserve the node address, network schedule, keeper, trunk, NAP, 24 V DC power and complete module order before replacement.

      PRODUCT & ORDER FAQS

      Questions buyers ask about 1794-ACN15

      • What network function does the 1794-ACN15 provide?

        It bridges one ControlNet channel to a compatible FLEX I/O assembly and transfers scheduled and unscheduled data for the installed modules.

      • How many FLEX I/O modules can be connected behind the adapter?

        The documented assembly supports up to eight compatible modules within the applicable power, terminal-base and connection limits.

      • How does ACN15 differ from an ACNR adapter?

        The 1794-ACN15 is a single-channel ControlNet adapter; ACNR catalog numbers are separate redundant-media executions and are not interchangeable by name alone.

      • Which ControlNet settings must be captured before adapter replacement?

        Record the node address, network schedule, keeper configuration, BNC trunk connection, NAP use and current diagnostic indications.

      • Why must the exact FLEX I/O module order be preserved?

        The controller configuration and network data layout correspond to the installed terminal bases and module positions, so changing the order can invalidate the I/O map.

      • What power information must be confirmed for the adapter and node?

        Verify the 24 V DC supply, wiring, polarity and the complete FLEX I/O node power requirements before energizing replacement hardware.

      • Can a different 1794-ACN15 hardware series be installed directly?

        Only after the Rockwell series-replacement guidance and compatibility with the installed ControlNet system, controller configuration and firmware are confirmed.

      • Which tests confirm that the ControlNet node is ready for service?

        Check adapter status, network communication, scheduled and unscheduled data, diagnostics and the operation of every connected FLEX I/O module.
