Information About 1734-ACNR

The Allen-Bradley 1734-ACNR I/O adapter provides an interface for communicating with and controlling I/O modules from a ControlNet network. This adapter offers several control solutions including high-speed data transfers between I/O devices and controllers. The 1734-ACNR handles redundant media and it supports local communication via the network access port.

With just one 1734-ACNR ControlNet Adapter, multiple I/O control connections can be established. For digital modules, up to 5 rack-optimized, I/O connections can be made per adapter. It also allows up to 25 direct connections for specialty and analog modules. The total number of supported connections in the network depends on the I/O configuration. The I/O capacity can be further expanded to as many as 63 I/O modules using multiple 1734-EP24DC power supplies. It is important to note that the 1734-ACNR can only control I/O modules from Series C or later. The adapter uses a standard 24 Volts DC power supply with 10.2W of maximum power. It has a maximum backplane current of 1 Amps at 5 Volts DC.

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.
