Product Introduction
In industrial networks, communication interruptions can halt production and corrupt data. The Schneider 170FNT11001 FIPIO Communication Module addresses this challenge with built-in fail-state logic. Part of the Modicon Momentum automation platform, this module maintains its last known value or falls back to zero on network failure, preserving system integrity. It supports up to 1 Mbit/s transmission over optical fiber or shielded twisted pairs, making it a reliable backbone for distributed control.
Technical Specifications Breakdown
The Schneider 170FNT11001 delivers key performance metrics that directly impact network reliability:
-
Transmission Rate: 1 Mbit/s ensures fast data exchange for real-time control loops.
-
Fail State: Configurable as maintain value or fallback to zero – critical for preventing actuator drift or data corruption.
-
Devices per Segment: Supports 0–31 nodes without a repeater and up to 97 with a repeater, offering flexible expansion.
-
Max Cable Distance: 5000 m via optical fiber allows wide-area coverage without signal degradation.
-
Access Method: Producer/consumer principle enables efficient peer-to-peer data sharing.
These specifications make the 170FNT11001 suitable for demanding applications where uptime is non-negotiable.
Industry Applications
The Schneider 170FNT11001 excels in sectors requiring deterministic communication over long distances. Common use cases include:
-
Water/Wastewater Treatment: Reliable data transmission across distributed pumping stations, with fail-state logic preventing valve misposition.
-
Material Handling: Synchronizes conveyor systems and palletizers, ensuring consistent operation even during brief network interruptions.
-
Process Manufacturing: Connects remote I/O clusters in chemical or food plants, maintaining process setpoints when a node drops offline.
In each scenario, the 170FNT11001’s ability to maintain or zero outputs reduces costly downtime and product waste.
Compatibility & Integration
This module integrates seamlessly with Schneider Modicon Premium and Momentum controllers via the FIPIO fieldbus. It uses the producer/consumer access method, which is native to FIPIO networks. The 170FNT11001 draws power directly from the I/O base, simplifying wiring. It supports both optical fiber (50/125 and 62.5/125) and shielded twisted-pair cable, so it can be retrofitted into existing installations without major rewiring. For systems using repeaters, the module’s segment capacity scales to 97 devices, making it suitable for large distributed architectures.
Troubleshooting & Common Issues
Communication modules often face issues like signal attenuation, incorrect termination, or power supply instability. The Schneider 170FNT11001 helps mitigate these through its fail-state mechanism. If a node fails, the module can either hold the last valid output or force outputs to zero – a choice that helps technicians isolate faults without disrupting the entire network. For long cable runs (up to 5000 m), ensure proper fiber end‑face cleaning and compliant shielded twisted-pair termination. The module’s CE marking guarantees adherence to European EMC standards, reducing interference risks. If a bus manager PLC (e.g., Premium) reports a communication error, verify the ‘Maintain value’ or ‘Fallback to zero’ setting in the configuration software to match your application logic.
Selection Guide & Purchasing Advice
Before ordering a Schneider 170FNT11001, verify your system’s bus management PLC (Premium or Momentum) and that the I/O base provides sufficient power. Confirm cable type compatibility – optical fiber for long runs, shielded twisted pairs for shorter segments. For networks exceeding 31 devices, purchase an appropriate FIPIO repeater.
