Operating as a gateway between high-speed industrial networks and field instruments, this module bridges ControlNet communication networks to two independent Foundation Fieldbus H1 segments. It delivers centralized configuration, seamless signal translation, and real-time process data integration for large-scale distributed control systems.\u003c\/p\u003e\n\u003ch3\u003eDual H1 Segment Gateway Infrastructure\u003c\/h3\u003e\n\u003cp\u003eEquipped with two independent H1 Foundation Fieldbus ports, the module manages up to 32 field instruments (up to 16 devices per H1 segment) operating at a standard 31.25 kbit\/s bus speed. Functioning as a Link Active Scheduler (LAS) on each segment, it controls bus communications and executes deterministic timing to ensure uninterrupted process loops and reliable transmitter feedback.\u003c\/p\u003e\n\u003ch3\u003eNetwork Bridging and System Integration\u003c\/h3\u003e\n\u003cp\u003eThe device bridges field-level H1 segments to higher-level automation controllers over ControlNet (C-Net). Through this gateway architecture, process engineers can configure field devices, run fieldbus function blocks, and continuously stream process diagnostics into ProcessLogix control systems using standard RSLogix 5000 \/ Studio 5000 software tools.\u003c\/p\u003e\n\u003ch3\u003eTechnical Parameters\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1757-FFLDC2\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley \/ Rockwell Automation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003eProcessLogix \/ ControlLogix\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDevice Type\u003c\/td\u003e\n\u003ctd\u003eFoundation Fieldbus H1 Linking Device\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHost Network Interface\u003c\/td\u003e\n\u003ctd\u003eControlNet (C-Net)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eField Network Interface\u003c\/td\u003e\n\u003ctd\u003e2x Foundation Fieldbus H1 Segments\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFieldbus Speed\u003c\/td\u003e\n\u003ctd\u003e31.25 kbit\/s per segment\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Connected Devices\u003c\/td\u003e\n\u003ctd\u003eUp to 32 H1 field devices (16 per segment)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBus Master Role\u003c\/td\u003e\n\u003ctd\u003eLink Active Scheduler (LAS) capable\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eDIN Rail or Chassis Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e1.54 lbs (0.70 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: What function does the 1757-FFLDC2 perform in a DCS architecture?
