      Information

      Information

      Overview Manuals Common Applications Product Precautions
      Allen-Bradley 1794-ACN15 connects one nonredundant FLEX I/O station to a ControlNet network and passes scheduled I/O traffic across the Flexbus.
      • Nonredundant ControlNet adapter
      • Eight-module FLEX I/O capacity
      • 5 Mbps communication rate
      • Valid node addresses 01 to 99

      Installed on a grounded 35 mm DIN rail, the adapter supplies the local Flexbus and retains the station node address, coax connection, 24 V DC feed and adjacent terminal-base arrangement.

      Important Notice: This is the nonredundant ACN15 execution. Use connector A, assign a unique node number and isolate adapter, backplane and field power before connection work.

      ControlNet FLEX I/O station
      Links a local bank of FLEX I/O modules to the configured scheduled network.
      Deterministic remote I/O
      Transfers time-critical I/O and approved messaging traffic over the installed coax system.
      Legacy adapter renewal
      Replaces the exact nonredundant adapter while preserving station address and topology.
      Network diagnostics
      Uses Status and Comm indicators to distinguish power, node, cable and configuration conditions.
      Allen-Bradley 1794-ACN15 installation checks: preserve the exact model identity, documented system arrangement and controlled acceptance evidence.
      1
      Confirm the full 1794-ACN15 marking; do not substitute a redundant ACNR version by family name.
      2
      Place the connected process and ControlNet station in an approved maintenance state.
      3
      Remove adapter, backplane and field power before cable, wiring or module work.
      4
      Record the node address, network schedule, station module list and firmware revision.
      5
      Connect the nonredundant ControlNet trunk only to connector A.
      6
      Ground the specified DIN rail and retain proper end anchors and enclosure protection.
      7
      Torque power terminals to 0.8 N m and keep power wiring within the published length.
      8
      Restore power and verify Status/Comm indications before proving all scheduled I/O.
