The IC698CPE010‑JU is a specific revision of the IC698CPE010, GE Fanuc’s 300 MHz VME‑based CPU module for the PACSystems RX7i (Series 90‑70) platform. The “JU” suffix denotes a particular hardware/firmware revision and configuration of the base CPE010 CPU.

What “‑JU” means

• In GE Fanuc part numbers, the trailing letters (e.g. ‑AA, ‑BB, ‑JU, ‑CD) indicate board revision, firmware baseline, and sometimes regional or customer‑specific configuration.
• For IC698CPE010‑JU, all core capabilities match the standard CPE010 family: 300 MHz Intel Celeron CPU, 10 MB battery‑backed RAM, 10 MB flash, embedded Ethernet and serial ports, VME64 backplane interface.
• The “JU” variant is often seen in new, factory‑sealed stock and may carry updated components or compliance markings compared with earlier revisions, but remains functionally interchangeable with other CPE010 revisions in most system designs.

Key specifications (typical for IC698CPE010 / CPE010‑JU)

From GE documentation and distributor data:

• Processor: 300 MHz Intel Celeron microprocessor with floating‑point support
• Memory:
  • 10 MB battery‑backed RAM for user program and data
  • 10 MB non‑volatile flash for program storage and firmware
• Execution speed: Boolean execution on the order of ≈ 0.2–0.33 ms per 1,000 coils/contacts (depending on firmware and configuration).
• Backplane: VME64 interface to RX7i racks (IC698CHS009/017/117 families, etc.)
• Communications:
  • 2× 10/100 Mbps Ethernet ports (auto‑sensing, half/full duplex)
  • 3× serial ports (RS‑232/RS‑485 style) supporting Modbus RTU, SNP, and generic serial I/O
• Power (nominal backplane requirements):
  • +5 VDC: ~3.2–3.4 A
  • +12 VDC / –12 VDC: small currents (tens of mA range)
• Environmental:
  • Operating temperature typically 0 °C to 50 °C (up to ~60 °C with fan‑cooled racks)

Practical implications

• Replacement / upgrade: If you’re replacing an existing IC698CPE010 (any revision) in an RX7i system, the ‑JU version is generally a direct drop‑in, assuming your firmware and application are compatible with the CPE010 family.
• Firmware: Exact firmware features (e.g., Ethernet protocols, diagnostics, web server behavior) can vary slightly by revision; GE’s RX7i CPU manuals (GFK‑2244 series) document revision‑specific notes.
