Product Advantages and Features
1. High-Speed Processing Performance
Faster Execution Speed:
Basic instruction execution time: 0.065μs (~3x faster than FX2N), ideal for high-speed logic control.
Enhanced floating-point arithmetic for complex calculations (e.g., PID control, data processing).
High-Speed Counting/Pulse Output:
Built-in 6 high-speed counters (single-phase 100kHz, dual-phase 50kHz).
Supports 3-axis independent pulse output (up to 100kHz), directly controlling stepper/servo motors (e.g., MR-J3/J4 servos).
2. Powerful Expandability
Modular Design:
Supports up to 8 expansion modules (compatible with FX2N series), max I/O points: 256.
Wide range of expansion modules:
Digital I/O (FX2N-16EX/EYR).
Analog I/O (FX3U-4AD/4DA, temperature module FX3U-4PT-PT100).
Communication modules (FX3U-485ADP, FX3U-ENET-L Ethernet).
Special Function Modules:
Positioning control (FX3U-20SSC-H, supports SSCNET III bus).
High-speed I/O (FX3U-16ET/ES).
3. Flexible Communication Capabilities
Built-in Communication Ports:
RS422/RS485 (supports Modbus RTU for HMI, inverters, etc.).
USB Programming Port (easy program download and monitoring).
Expansion Communication Modules:
Ethernet (FX3U-ENET-L, supports TCP/IP, FTP).
CC-Link (FX3U-64CCL, for distributed I/O control).
Profibus-DP (FX3U-232ADP, compatible with Siemens devices).
4. High Reliability & Stability
Industrial-Grade Design:
Operating temperature: -20°C to 60°C, strong resistance to vibration/interference.
Built-in watchdog timer (WDT) to prevent program crashes.
Data Backup:
Built-in flash memory (no battery required for program storage).
Optional battery (FX3U-32BL) for data backup.
5. Easy Programming & Debugging
GX Works2 Programming Software:
Supports Ladder Logic (LD), Instruction List (IL), Structured Text (ST).
Built-in simulation function for offline debugging.
Rich Instruction Set:
Over 300 application instructions, including PID control, data operations, string processing.
Supports subroutine calls and function blocks (FB) for code reuse.
6. Cost-Effectiveness & Compatibility
Affordable Price:
More budget-friendly than FX5U, suitable for cost-sensitive projects.
Backward Compatibility with FX2N:
Directly supports FX2N expansion modules (e.g., FX2N-16EX, FX2N-4AD), reducing upgrade costs.
