GE IC693CPU363-CH

  • Product Introduction: This is an enhanced mid-range CPU for the GE Fanuc 90-30 PLC platform. The “CH” suffix denotes the North American / Canadian market variant. It features 256KB of user memory, dual Ethernet ports (one for programming, one for HMI/SCADA), and a math coprocessor for fast floating-point calculations. It is the upgrade path from the IC693CPU360 and is designed for applications requiring more memory, faster math, and redundant network connectivity.

    • Front panel: 6 LEDs + 2 RJ-45 Ethernet ports
    • Battery compartment on front
    • Gold-plated backplane connector with keying
    • DIN-rail or chassis mount
  • Working Principle:
    • Similar to IC693CPU360 but with hardware FPU offloading floating-point calculations from the main CPU. Dual Ethernet ports operate independently — port 1 handles programming/upload, port 2 handles real-time HMI/SCADA traffic. The Genius Bus manages all I/O communication. The scan cycle reads inputs, executes logic (with FPU accelerating math-heavy blocks), and writes outputs.
  • Installation Requirements:
    • IC693CHS or IC693ACC chassis
    • Connect Ethernet port 1 to programming PC, port 2 to HMI/SCADA network
    • Use CAT5e or better cabling
    • Configure separate IP subnets for each Ethernet port to avoid conflicts
    • Ensure 24VDC chassis power is stable (IC693PWR330 recommended)
  • Usage Precautions:
    • Replace battery every 5 years
    • Do not connect both Ethernet ports to the same subnet — causes IP conflict
    • Use shielded Ethernet cable in high-EMI areas
    • Do not exceed 512KB total memory with expansion modules
    • For redundant networks, use managed switches with RSTP support
    • Do not hot-swap
