Engineering Advantages
The 1788-EN2DNR solves a common integration challenge: connecting legacy DeviceNet field devices to modern EtherNet/IP control systems without replacing installed infrastructure.
Engineers install the module directly on a DIN rail inside standard control cabinets. The compact open-type enclosure fits easily into space-constrained panels. Dual Ethernet ports allow daisy-chain wiring, reducing switch requirements and simplifying panel layout.
The device maintains stable communication under industrial electrical noise. It isolates DeviceNet and Ethernet segments, minimizing interference and improving signal integrity in high-EMI environments such as motor control centers and process plants.
The built-in web server accelerates commissioning. Engineers access diagnostics through a browser, identify node faults, and adjust parameters without dedicated configuration software. This reduces downtime during startup and maintenance.
The module supports multiple CIP connection classes, enabling real-time I/O control, monitoring, and explicit messaging simultaneously. This flexibility supports both high-speed automation tasks and supervisory data exchange.
FAQs
Q1: Can this module replace older DeviceNet scanners?
Yes. The 1788-EN2DNR replaces traditional DeviceNet scanner modules by providing Ethernet-based control access while maintaining compatibility with existing DeviceNet devices.
Q2: How many devices can I connect on the DeviceNet side?
You can connect up to 63 DeviceNet slave devices, depending on network power and topology constraints.
Q3: Does the device require special configuration software?

Tech & Buying Guide
Understanding Marshalling Cabinets in Industrial Control Systems Architecture
Industrial control system deployments rely on structured signal distribution to bridge field instrumentation with central processing hardware. A marshalling cabinet serves as the vital intermediate connection point between heavy field home-run multi-pair cables and delicate input/output (I/O) modules housed inside Programmable Logic Controller (PLC) or Distributed Control System (DCS) enclosures. By segregating field cable terminations from control hardware, engineers maintain system flexibility, safeguard controller components, and streamline commissioning workflows.
FAT vs SAT in Industrial Control Systems: Key Differences and Execution Guide
Industrial control system deployment relies on strict verification protocols to guarantee operational safety, system stability, and regulatory compliance. Commissioning complex Programmable Logic Controller (PLC) racks, Distributed Control Systems (DCS), and Safety Instrumented Systems (SIS) requires two critical milestones: the Factory Acceptance Test (FAT) and the Site Acceptance Test (SAT). Both procedures validate that system automation meets design specifications, but they occur at different stages of project execution and target distinct operational risks.
Hub vs Switch vs Router in Industrial Automation Architecture
Modern factory automation relies on reliable industrial networking infrastructure to exchange real-time field data across operational technology systems. Engineers often encounter networking hardware like hubs, switches, and routers when integrating Programmable Logic Controllers, Distributed Control Systems, and SCADA monitoring nodes. Although these devices share physical ports, they operate at different layers of the Open Systems Interconnection reference model and deliver distinct traffic management capabilities.
