The IC698CPE010 is GE Fanuc’s 300 MHz VME‑based CPU module for the PACSystems RX7i (Series 90‑70) platform. It’s the entry‑performance RX7i processor, widely used in mid‑size to large automation systems.

Core features

• Processor: Intel Celeron 300 MHz microprocessor with floating‑point support.
• Memory:
  • 10 MB battery‑backed RAM for user program and data
  • 10 MB non‑volatile flash (NVRAM) for program storage and firmware
• Execution speed: Typical Boolean execution around 0.33 ms per 1,000 contacts/coils.
• Program structure: Supports up to 512 program blocks (max ~128 KB per block).
• I/O references:
  • Discrete %I / %Q: up to 32 Kbits each
  • Analog %AI / %AQ: configurable up to 32 Kwords each
  • %W (bulk memory): configurable up to the full available user RAM.

Communications and interfaces

• Backplane: VME64 bus to the rack backplane for CPU‑to‑I/O and option‑module communication.
• Ethernet: 2× embedded 10/100 Mbps auto‑sensing Ethernet ports (half/full duplex).
• Serial ports: 3 embedded serial ports (RS‑232 / RS‑485 style) supporting protocols such as:
  • Modbus RTU slave
  • SNP (Serial Network Protocol)
  • Generic serial I/O
• Web / diagnostics: Supports web‑based data monitoring and remote diagnostics (multiple concurrent network server connections).

Power and environment

Typical power and environmental specs from GE documentation and distributors:

• Backplane power requirements (nominal):
  • +5 VDC: ~3.2 A
  • +12 VDC: ~0.042 A
  • –12 VDC: ~0.008 A
• Operating temperature:
  • 32 °F to 122 °F (0 °C to 50 °C) standard
  • Up to 140 °F (~60 °C) with a fan‑cooled rack/tray
• Real‑time clock: Time‑of‑day clock with typical accuracy on the order of seconds per day; elapsed‑time clock accuracy ~0.01 %.

Programming and software

• Languages: Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), and C (via appropriate toolchains).
• Symbolic variables: Supports auto‑located symbolic variables that can use any portion of user memory.
• Firmware updates: Firmware can be updated in the field without hardware replacement (via GE’s RX7i firmware upgrade utility).

Typical use cases

• Mid‑range to large discrete and process control applications where 300 MHz performance and 10 MB user memory are sufficient.
• Systems requiring VME‑based modularity with mixed Series 90‑70 I/O, specialty modules, and Ethernet/serial communications.
