Allen-Bradley 1788-EN2FFR ControlNet-to-EtherNet/IP Linking Device – 1788 Series
When a ControlNet segment loses its bridge to the EtherNet/IP backbone, the consequences cascade instantly: HMI screens go blank, SCADA systems lose visibility, and production lines halt without warning. Maintenance engineers scramble to diagnose a fault that may span two entirely different network protocols, while every minute of downtime translates directly into lost output and escalating costs. The Allen-Bradley 1788-EN2FFR exists precisely to prevent this scenario — it is the critical translation layer that keeps your legacy ControlNet infrastructure communicating seamlessly with modern EtherNet/IP systems, ensuring uninterrupted data flow across your entire automation architecture.
Within Rockwell Automation’s 1788 Linking Device series, the 1788-EN2FFR occupies a strategic position as the dual-port EtherNet/IP variant with integrated ControlNet media redundancy support. As industrial facilities worldwide transition toward unified Ethernet-based architectures while maintaining substantial investments in ControlNet infrastructure, this module has become a cornerstone component in brownfield integration projects across automotive, oil & gas, food & beverage, and discrete manufacturing sectors globally.

- Brownfield Integration Ready: Ideal for facilities upgrading to EtherNet/IP infrastructure while retaining existing ControlNet I/O, drives, and controllers.
- Compact DIN-Rail Form Factor: Space-efficient design fits standard control panel layouts without requiring additional enclosure space.
- Wide Industrial Temperature Range: Rated for harsh industrial environments from 0°C to 60°C ambient.
Industry & Equipment Applications
- Automotive Manufacturing: Body welding lines, paint shop conveyors, and assembly robots using legacy ControlNet I/O with modern EtherNet/IP supervisory systems.
- Oil & Gas: Pipeline SCADA integration, compressor station control, and wellhead automation where ControlNet PLCs interface with EtherNet/IP DCS platforms.
- Food & Beverage: Packaging lines, filling machines, and CIP (Clean-in-Place) systems requiring reliable cross-protocol communication.
- Water & Wastewater: Pump station control and treatment plant SCADA systems bridging older ControlNet networks to modern Ethernet infrastructure.
- Discrete Manufacturing: Machine tool control, press lines, and material handling systems with mixed-generation network architectures.
- Power Generation & Utilities: Substation automation and turbine control systems requiring deterministic ControlNet communication with Ethernet-based SCADA.

Frequently Asked Questions
Q: What is the difference between 1788-EN2FFR and 1788-EN2F?
A: The 1788-EN2FFR features dual EtherNet/IP ports supporting Device Level Ring (DLR) topology for Ethernet media redundancy, whereas the 1788-EN2F has a single EtherNet/IP port. Both support dual ControlNet BNC ports for ControlNet media redundancy. Choose the EN2FFR for applications requiring Ethernet ring topology resilience.
Q: Can the 1788-EN2FFR connect a ControlLogix controller to ControlNet I/O without a ControlNet scanner card in the chassis?
A: Yes. The 1788-EN2FFR allows an EtherNet/IP-connected ControlLogix controller to own and communicate with ControlNet I/O adapters across the linked ControlNet segment, effectively acting as the ControlNet network manager and bridge — eliminating the need for a 1756-CNB module in the controller chassis in many configurations.
Q: Is the 1788-EN2FFR compatible with Studio 5000 / RSLogix 5000?
A: Yes. The module is fully supported by Rockwell Automation’s Studio 5000 Logix Designer and RSLinx Classic/Enterprise. RSNetWorx for ControlNet is required for ControlNet network scheduling configuration.
Q: What firmware version should I use?
A: Firmware requirements depend on your controller firmware and Studio 5000 version. Please consult the Rockwell Automation Product Compatibility and Download Center (PCDC) or contact our technical team with your system details for guidance.
Q: Do you supply new, surplus, or refurbished units?
A: We supply new-in-box, factory-sealed units as well as tested surplus stock. All units are clearly identified by condition in your quotation. We do not supply unmarked or unverified refurbished units.
Q: How long does international shipping take?
A: Standard express shipping (DHL/FedEx) to most destinations takes 3–7 business days. Expedited options are available. Lead time for sourcing varies by stock availability — confirmed at time of quotation.
