FP-1601
National Instruments FP-1601 – Network Interface Module
Overview
The National Instruments FP-1601 is a network interface module that connects up to nine FieldPoint I/O modules to a high-speed Ethernet network. It enables reliable, event-driven communications at speeds of up to 100 Mb/s, making it easy to interface with a PC or embedded controller for distributed measurement and automation applications.
The FP-1601 acts as a bridge between the host PC and FieldPoint I/O modules, using a local high-speed bus for communication. It includes diagnostic and autoconfiguration features to simplify installation, operation, and maintenance.
Key Features
✅ Ethernet Communication: Supports 10BaseT and 100BaseTX networks via RJ-45 connector.
✅ High-Speed Data Transfer: Up to 100 Mb/s data rates for efficient network performance.
✅ Event-Driven Architecture: Sends data only when changes occur to reduce unnecessary Ethernet traffic.
✅ Publisher-Subscriber Model: Multiple PCs can subscribe to data updates, enabling efficient distributed networking.
✅ Flexible System Configuration: Supports up to 9 FieldPoint I/O modules, making it easy to scale.
✅ Compatible with NI Software: Works with LabVIEW, LabWindows/CVI, Measurement Studio, Lookout, and OPC client applications.
✅ Compact, DIN-Rail Mountable: Snaps together with FieldPoint bases for easy installation.
Applications
Industrial Automation – Controls and monitors sensors, actuators, and control systems.
Remote Monitoring & Data Logging – Collects real-time field data for analysis and predictive maintenance.
Process Control – Ideal for SCADA systems, environmental monitoring, and industrial control networks.
Machine Condition Monitoring – Provides real-time updates on equipment status and performance.
Network Communications Interface
The FP-1601 connects directly to Ethernet networks and uses standard TCP/IP protocols for compatibility with existing network infrastructures. Key features include:
✔ Auto-Negotiation for 10/100 Mb/s – Adjusts speed based on network conditions.
✔ Event-Driven Communication – Publishes data only when values change, reducing bandwidth usage.
✔ Dead Band Settings – Prevents insignificant signal changes from triggering unnecessary updates.
System Configuration & Scalability
Manages up to 9 FieldPoint bases and I/O modules.
Modules connect via a local high-speed data bus for rapid communication.
Modular terminal bases allow easy expansion as system requirements grow.
DIN rail mounting provides compact, space-efficient installation.
