GE Fanuc IC693CPU372 Series 90-30 CPU Module
The GE Fanuc IC693CPU372-AD, also cataloged as the IC693CPU372 CPU Module, operates as a dedicated hardware component for centralized program execution and real-time network communications within Series 90-30 PLC platforms. Driven by a 133 MHz 32-bit AMD SC520 processor, the unit executes boolean logic at 0.22 ms per 1K instruction elements across up to 4,096 I/O points. Integrated dual 10/100 Mbps Ethernet ports support Ethernet Global Data (EGD) protocols, enabling direct interfacing with host SCADA systems and distributed PLC racks.

Backplane Bus Communication Velocity and System Determinism
The GE Fanuc IC693CPU372-AD CPU module manages high-speed backplane bus communication velocity across Series 90-30 rack structures to ensure sub-millisecond execution cycles. The integrated dual Ethernet ports run on an internal auto-sensing switch framework, facilitating deterministic Ethernet Global Data (EGD) exchanges without processor scan delays. Onboard firmware flash compatibility simplifies system upgrades while preserving logic memory contents stored in battery-backed RAM during backplane power cycles.
Frequently Asked Questions
Q: How does the module handle backup memory during backplane power loss?
A: The module relies on a dedicated lithium battery mounted to the Series 90-30 power supply module to retain user program logic and register data stored in the 240 KB RAM.
Q: What are the backplane power supply current requirements for the IC693CPU372-AD?
A: The CPU module draws its operational power directly from the 5 VDC rail on the Series 90-30 rack backplane, supplied by the main chassis power supply module.
Q: Can program logic be loaded onto the controller without an active software connection to a PC?
A: Yes, the unit supports the EZ Store Device hardware unit, which allows field engineers to transfer firmware and user program logic directly into flash memory without connecting a computer.
Field Installation Guidelines
Follow these core engineering procedures when installing or replacing the processor module:
- Power Isolation: De-energize the Series 90-30 baseplate rack before inserting or removing the CPU module to prevent backplane edge connector damage.
- Module Alignment & Seating: Align the rear circuit board connectors with the leftmost slot (Slot 1) of the primary Series 90-30 baseplate. Press firmly at the top and bottom of the module until the retaining lever clicks into place.
- Electrostatic Discharge Handling: Wear a grounded ESD wrist strap and handle the module exclusively by its plastic housing to protect internal silicon circuits from static discharge.
- Communication Cable Grounding: Use shielded twisted-pair cables for RS-485 and Category 5e shielded cables for Ethernet connections, grounding cable shields at a single earth ground terminal to block electromagnetic interference (EMI).
- Thermal Management: Ensure vertical cooling vents above and below the baseplate remain unobstructed to maintain airflow, keeping the ambient cabinet environment within 0 to +60 deg C.
