Working Principle:
The ARM9 processor executes the user program (written in IEC 61131-3 compliant languages: LD, FBD, SFC, ST, IL) stored in Flash memory. The Windows CE real-time kernel manages task scheduling, communication stacks, and the integrated motion control engine. I/O is scanned cyclically with a minimum scan time of 0.5 ms for the CPU module. Communication with remote I/O, HMIs, and SCADA systems is handled via Ethernet (Modbus TCP, EtherNet/IP), RS-485 (Modbus RTU), and RS-232C.

Advantages & Highlights:

• Windows CE platform enables rich HMI integration and data logging directly on the PLC
• Built-in motion control (2-axis pulse output, 4-axis high-speed counter) eliminates need for separate motion controller
• Dual Ethernet ports support redundant network configurations
• IEC 61131-3 compliant programming with FBD, LD, ST, SFC, IL languages
• Supports Yokogawa FAIR Planner programming software

Applicable Industries:

• Machine building (packaging machines, CNC machines, conveyors)
• Semiconductor manufacturing equipment
• Food and beverage packaging lines
• Printing and converting machinery
• Material handling and logistics automation

Installation Requirements:

• Mount on DIN rail in a control cabinet with adequate ventilation
• Connect DC 24 V power supply with minimum 2 A capacity (for CPU + I/O modules)
• Terminate Ethernet cables with shield grounding at one end only
• Use Yokogawa FA-M3 series I/O modules for expansion (no mixing with FA-M1 series)

Usage Precautions:

• Do not disconnect power while the CPU is writing to Flash memory (use battery backup or UPS)
• Do not exceed the total I/O point count (2,048 max) including remote I/O
• Update firmware only using Yokogawa FAIR Planner software via USB or Ethernet
• Ensure the SD card is formatted in FAT32 for data logging compatibility
