Product Details
Product Description
The 1788-CN2FFR is a specialized industrial network bridge designed to integrate FOUNDATION Fieldbus (FF) H1 segments directly into a ControlNet architecture. This linking device functions as a high-speed gateway, allowing controllers on a ControlNet network to communicate seamlessly with field-level instrumentation. By acting as the primary interface between these two distinct protocols, the 1788-CN2FFR (Part Number: 1788-CN2FFR) enables centralized configuration and asset management of fieldbus devices within a Process Automation System.
Engineered for mission-critical reliability, the module features dual BNC connectors to support redundant ControlNet media, ensuring continuous operation even in the event of a single cable failure. The device is housed in an open-style enclosure optimized for 35mm DIN rail mounting and is specifically designed for process control environments where high-speed data exchange and robust physical layer isolation are mandatory.

Integration and Application
This linking device is typically utilized in large-scale process plants where legacy ControlNet backbones must interface with modern smart instrumentation. The 1788-CN2FFR simplifies the network layer by allowing engineers to map Fieldbus device data directly into the ControlNet I/O image, effectively bridging the gap between plant floor control and field-level sensing.
Engineering FAQ
Does the 1788-CN2FFR support redundant media on both networks?The module is designed with redundant ControlNet BNC ports for high-availability communication. On the FOUNDATION Fieldbus side, it manages H1 segments; redundancy at that level is typically handled by the network architecture and segment design rather than the linking device itself.
What cabling is required for the ControlNet connection?Standard ControlNet RG-6 coaxial cable with BNC connectors is required for the primary ports. For any Ethernet-based configuration or diagnostic bridging, CAT5 Shielded Twisted Pair (STP) is recommended to maintain signal integrity in high-noise environments.

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.
