DeviceNet Network Integration Solution — Allen-Bradley 1734-ADN | Point I/O Series
Where This Product Is Used
The Allen-Bradley 1734-ADN DeviceNet Adapter Module is the communication gateway that connects Point I/O distributed I/O assemblies to a DeviceNet fieldbus network. It is specified by control engineers across a wide range of industrial environments where DeviceNet remains the backbone of machine-level communication:
- Automotive Assembly Lines — Body-in-white welding cells, paint shop conveyors, and final assembly stations where DeviceNet coordinates hundreds of discrete I/O nodes across a single trunk line.
- Food & Beverage Processing — Bottling lines, filling machines, and packaging conveyors requiring hygienic, compact I/O nodes with deterministic scan times.
- Material Handling & Conveyor Systems — Sortation systems, palletizers, and automated storage/retrieval systems (AS/RS) where distributed I/O reduces panel wiring complexity.
- Pharmaceutical Manufacturing — Validated production lines where Point I/O’s modularity supports incremental system changes without full rewiring.
- Water & Wastewater Treatment — Remote pump stations and valve manifold islands where DeviceNet’s robust noise immunity and power-over-bus capability simplify field installation.
- OEM Machine Builders — Compact machine designs where the 1734-ADN’s small footprint and DIN-rail mounting reduce panel real estate while maintaining full DeviceNet node functionality.

Why Engineers Specify This Model
- Proven DeviceNet Interoperability — Fully ODVA-compliant, the 1734-ADN integrates seamlessly with any DeviceNet master scanner (e.g., 1756-DNB, 1769-SDN) and third-party DeviceNet PLCs without custom configuration.
- Modular, Scalable Architecture — Point I/O’s single-module granularity means engineers add exactly the I/O type and count needed — no wasted slots, no oversized chassis.
- Compact DIN-Rail Footprint — At 12 mm wide per module, Point I/O assemblies fit in panels where traditional rack-based I/O cannot, critical for space-constrained OEM machine designs.
- Hot-Swap Capable — Modules can be replaced under power (with appropriate power supply configuration), minimizing unplanned downtime during maintenance windows.
- Rotary Switch Node Addressing — Physical MAC ID setting eliminates software-only addressing errors during commissioning and simplifies field replacement by technicians.
- Extensive Diagnostic Visibility — Network status, module status, and I/O fault LEDs provide immediate visual diagnostics without requiring a laptop or programming tool on-site.

Application-Specific FAQ
Q: Can the 1734-ADN be used with a non-Rockwell DeviceNet master?
A: Yes. The 1734-ADN is ODVA-compliant and will operate with any certified DeviceNet master scanner, including those from Siemens, Omron, Beckhoff, and other vendors, provided the EDS file is imported correctly into the master’s configuration tool.
Q: How many I/O modules can one 1734-ADN support?
A: The adapter supports up to 63 Point I/O modules on a single backplane assembly, subject to the total input/output data size limits (248 bytes each) and the power budget of the installed power supply module.
Q: Is the 1734-ADN compatible with Studio 5000 / RSLogix 5000?
A: The 1734-ADN is configured via RSNetWorx for DeviceNet, not directly in Studio 5000. The DeviceNet scanner module (e.g., 1756-DNB) is added to the Studio 5000 project, and the 1734-ADN node is configured within RSNetWorx and mapped to the scanner’s I/O table.
Q: What is the difference between 1734-ADN and 1734-ADNX?
A: The 1734-ADNX is an extended-node variant supporting larger I/O data sizes and additional diagnostic features. The standard 1734-ADN is sufficient for the majority of machine-level DeviceNet applications. Contact Konmask if you are unsure which variant your application requires.
Q: Can I replace a 1734-ADN without reconfiguring the DeviceNet network?
A: Yes, provided the replacement module is set to the same MAC ID (node address) via the rotary switches. The DeviceNet master will recognize the node at the same address without requiring a full network reconfiguration.
Q: Do you supply the EDS file for the 1734-ADN?
A: The official EDS file is available from Rockwell Automation’s Product Compatibility and Download Center (PCDC). Konmask can assist in locating the correct EDS file version for your firmware revision upon request.
