- Integrates ProcessLogix control strategies with two independently managed H1 links
- Uses a companion remote termination panel for field-side H1 connections
- Requires preserved schedules, device assignments, firmware, and controller project data
1757-FIM is an Allen-Bradley ProcessLogix FOUNDATION Fieldbus Interface Module for integrating controller strategies with H1 field-device networks.
The double-width module uses a companion remote termination panel and supports independent scheduling and link-management functions for two H1 links.
Before replacement, preserve the ProcessLogix project and verify chassis allocation, remote panel and cable, firmware, H1 segment power, terminators, devices, and schedules.
Availability, condition, price, and shipping time for 1757-FIM are confirmed during quotation.

- Install the module only in the documented non-redundant chassis arrangement
- Match the companion termination panel, interconnection cable, and both H1 link assignments
- Confirm controller and server capacity before adding field devices or control strategies
- Treat each 1757-FIM as the processing equivalent of three I/O modules when calculating ProcessLogix capacity.
- For allocation, use the 1757-FIM count plus the total I/O-module count divided by three; do not exceed 21 per controller or 100 per server.
- Each 1757-FIM supports two independent H1 links; the documented system limits are 42 H1 links per controller and 200 per server.
- Review module indicators and Control Builder monitoring before replacing hardware
- Check panel connection, segment power, terminators, wiring, and field-device communication
- Confirm scheduled and unscheduled data exchange before returning control to the process
- ProcessLogix control strategies communicating with FOUNDATION Fieldbus instruments
- Two-link H1 networks serving distributed process measurement and control devices
- Industrial process systems using fieldbus function blocks and scheduled communication
