Features:

  • Gateway Between Ethernet/IP Networks and FOUNDATION Fieldbus H1 Devices
  • Integrates High-Speed Ethernet Connectivity with Dual H1 Port Fieldbus Support
  • Functions Seamlessly Within Allen-Bradley ControlLogix System Architectures
The Allen-Bradley 1757-FFLD2/A serves as the FOUNDATION Fieldbus Linking Device in industrial control networks, establishing robust communication pathways between Ethernet/IP infrastructure and fieldbus instrumentation. It continuously bridges high-speed Ethernet protocols (10/100 Mbps EtherNet/IP and HSE) with H1 fieldbus segments (31.25 kbps), enabling centralized access to distributed process control devices across the manufacturing floor. Reliable data transfer is inherent to the 1757-FFLD2/A design, with each H1 port supporting up to 8 to 10 FOUNDATION Fieldbus devices and accommodating 16 publisher and 16 subscriber VCR connections per network. The 1757-FFLD2/A delivers significant advancements in industrial networking integration, incorporating dual Ethernet ports and comprehensive protocol support within the ControlLogix ecosystem.

The 1757-FFLD2/A provides essential communication functions bridging disparate network domains, serving as a critical component of the control path that directly influences the proper, coordinated operation of distributed process systems. One 1757-FFLD2/A module is required per ControlLogix chassis to establish FOUNDATION Fieldbus connectivity, with the device occupying a standard slot position within the rack. The 1757-FFLD2/A operates on 18 to 36 VDC input power (nominal 24 VDC) with maximum consumption of 36 watts and input current up to 1.5 amperes.

For comprehensive industrial networking applications, the 1757-FFLD2/A ensures continuous operation through robust electrical isolation and surge protection mechanisms. In addition to standard protocol translation functions, the module maintains 500 V RMS isolation voltage between Ethernet and H1 networks. The 1757-FFLD2/A withstands surges of ±2 kV across H1 ports and demonstrates immunity to electrostatic discharge rated at 8 kV air discharge and 6 kV contact discharge. Using these protective measures, the 1757-FFLD2/A continually safeguards communication integrity across both network domains. If the system detects electrical disturbances or transient events that could compromise data transmission, the isolation barriers and surge suppression circuitry maintain stable operation and preserve diagnostic event records within the ControlLogix controller.

The 1757-FFLD2/A Allen-Bradley ControlLogix Communication Module may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
