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
Strategic Selection: Choosing the Right SCADA Software for Your PLC Project
In industrial automation, the SCADA (Supervisory Control and Data Acquisition) system acts as the bridge between raw machine data and actionable human intelligence. Selecting the incorrect software platform can lead to integration bottlenecks, scalability issues, and excessive long-term maintenance costs. As an automation consultant with 15 years of experience, I have guided many projects through the selection process. Below are the essential criteria for choosing a platform that ensures both performance and longevity.
Ensuring Operational Continuity: The Strategic Value of Redundant Automation Systems
In modern industrial landscapes, unplanned downtime is the ultimate adversary. For sectors relying on complex PLC and DCS architectures, a single hardware failure can trigger catastrophic production losses. Therefore, implementing redundant automation systems is no longer a luxury; it is a fundamental requirement for mission-critical operations. In this article, I analyze why redundancy remains the backbone of reliable industrial infrastructure.
Selecting the Right Cables for Industrial Automation: A Comprehensive Guide
Selecting the appropriate cabling infrastructure is critical for the success of any industrial automation project. Improper cable selection often leads to signal degradation, system instability, and costly downtime. As an automation engineer, I frequently see projects compromised by poor cabling choices in harsh industrial environments. This guide simplifies the complex landscape of cabling to help you make informed decisions for your PLC, DCS, and control systems.
