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?
No. The integrated web server allows direct configuration, diagnostics, and monitoring through a standard web browser.

Q4: What should I consider during installation?
Ensure stable 24 V DC power supply, proper grounding, and correct DeviceNet termination. Maintain cable separation from high-power lines to reduce electromagnetic interference.
