Information About 1734-ACNR

The 1734-ACNR is a ControlNet adapter within the Allen-Bradley POINT I/O family, enabling distributed I/O assemblies to communicate with ControlNet controllers. It features a compact, modular construction that mounts directly on DIN rail alongside POINT I/O modules for flexible system expansion. Compatible with Series C and later POINT I/O modules, it supports local and media-redundant communication for improved reliability in critical applications. Typical usage includes high-speed, deterministic I/O control in systems requiring up to 63 modules when paired with additional POINT I/O power supplies.

Key Features:

  • ControlNet network interface: Provides deterministic, high-speed control for POINT I/O modules.
  • Modular DIN-rail design: Supports up to 63 modules using expansion power supplies.
  • 24 VDC powered adapter: Operates with reverse-polarity protection for system safety.
  • 1 A POINTBus output: Supplies backplane power to connected POINT I/O modules.
  • Supports redundant media: Enhances network reliability in mission-critical systems.
  • Multiple I/O connection types: Up to 5 rack-optimized and 25 direct connections.
  • Integrated overvoltage protection: Protects against wiring and transient power issues.
  • Compact construction: Ideal for distributed control architectures with space constraints.

The 1734-ACNR delivers the reliability and precision required for distributed ControlNet-based I/O applications.

    Frequently Asked Questions about 1734-ACNR
    Question: What is the 1734-ACNR used for?
    Date Update:23/06/2025
    Answer:

    The 1734-ACNR is a ControlNet communication adapter for POINT I/O systems, enabling distributed I/O over Rockwell’s ControlNet deterministic network. It's used in industrial automation systems where precise timing and control are essential — such as motion control, high-speed packaging, or manufacturing cells.

    It supports:

    • Real-time control data
    • Deterministic scheduled messaging
    • Connectivity to up to 63 POINT I/O modules
    Question: What are the primary specifications of the 1734-ACNR?
    Date Update:23/06/2025
    Answer:
    • Network: ControlNet (media redundancy supported)
    • Power Supply Voltage: 24V DC nominal (range: 19.2–28.8V DC)
    • Backplane current: 1000 mA (total for I/O modules)
    • Communication rate: 5 Mbps (fixed for ControlNet)
    • Module slots supported: Up to 63 POINT I/O modules
    • LED indicators: Provide status for module, network A/B, and I/O health
    Question: How do I configure the 1734-ACNR on a ControlNet network?
    Date Update:23/06/2025
    Answer:

    Configuration steps:

    1. Set the node address using DIP switches on the module.
    2. Use RSNetWorx for ControlNet to define the scanlist and schedule the network.
    3. Connect ControlNet coax or fiber and termination resistors.
    4. Use Studio 5000 (or RSLogix 5000 for legacy systems) to add the module to your I/O tree via its EDS/AOP profile.

    Make sure:

    • The baud rate is fixed at 5 Mbps.
    • Each node has a unique address.
    • Network is properly scheduled in RSNetWorx.
    Question: What are the LED indicators and what do they mean?
    Date Update:23/06/2025
    Answer:

    There are 4 primary LEDs:

    • Module Status (MOD): Green (OK), Red (fault), Flashing = diagnostic
    • Network A/B: Solid green (normal), flashing green (standby), red (error)
    • POINTBus Status (I/O): Indicates health of connected I/O modules

      Refer to the manual for exact blink patterns — these are critical for fast diagnostics.
    Question: Can the 1734-ACNR be mixed with other POINT I/O network adapters?
    Date Update:23/06/2025
    Answer:

    Each POINT I/O network segment can only contain one network adapter (ACNR, AENT, etc.). However, multiple segments (adapters) can coexist in the same control system, each with its own network connection.
