GE Fanuc IC693CPU352 Series 90-30 High-Performance Processor Module

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The GE Fanuc IC693CPU352 is an advanced single-slot modular CPU module engineered for Series 90-30 PLCs. Featuring a 32 MHz 80386EX processor and 80K Bytes of configurable user memory, it handles large-scale process control, extensive floating-point calculations, and heavy multi-rack data exchange.

Securing the IC693CPU352 as New Surplus is a high-value supply chain strategy for facilities running extensive Series 90-30 infrastructure. Purchasing uninstalled, factory-fresh original stock mitigates the high risks of memory degradation, timing faults, and unexpected system downtime associated with used hardware while avoiding the massive capital expense of a full PLC platform migration.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Execute Lock-Out/Tag-Out (LOTO) procedures on the power source feeding the main CPU baseplate.
2. Put on an ESD grounded wrist strap to shield high-density memory ICs and processor chips from static damage.
3. Verify that a fresh RAM backup battery (IC693ACC301) is installed in the power supply to ensure program retention upon initialization.

Stage 2: Removal

1. De-energize the baseplate rack power supply and unplug any serial communications hardware.
2. Squeeze the release levers at the top and bottom of the existing CPU card in Slot 1.
3. Slide the card straight forward from the backplane guide rails to protect card-edge connectors.

Stage 3: Installation (Clone & Seat)

1. Position the rear card edge of the replacement IC693CPU352 into Slot 1 of the CPU Main Baseplate (IC693CHS397 or IC693CHS391).
2. Apply firm, steady pressure on the front face of the module until top and bottom latches snap locked.
3. Ensure backplane keying alignment is complete before securing front panel latches.

Stage 4: Power-On & Testing

1. Reapply main power to the PLC rack power supply.
2. Check that the front panel “PWR” and “OK” LEDs illuminate solid green, signaling a successful power-on self-test (POST).
3. Connect via Proficy Machine Edition or Logicmaster 90 over an RS-485 SNP interface cable, download/verify system logic, and command the processor into RUN mode.

Firmware/Software Versions & Upgrade Notes

• Software Compatibility: Fully supported by Proficy Machine Edition (PME) Release 3.0 or higher, as well as legacy Logicmaster 90-30 software version 8.0 or higher.
• Firmware Dependencies: The IC693CPU352 utilizes flash-based operating system firmware. Ensure replacement processors meet or exceed the firmware revision (e.g., Version 10.0 or higher) required by your program logic, especially when communicating with Ethernet Interface Modules (IC693CMM321).
• Slot Restrictions: Must be installed in Slot 1 of a standard CPU main baseplate (IC693CHS397 or IC693CHS391). It cannot be used in embedded CPU chassis (like the CPU311) or expansion racks.

Frequently Asked Questions (FAQ)

Is this IC693CPU352 processor a brand new unit or pulled/refurbished stock?

This product is a Brand New Surplus unit. It is not used, not pulled from a decommissioned plant, and not refurbished. All modules undergo rigorous quality verification to ensure OEM-level reliability.

What is the primary operational advantage of buying New Surplus for main CPU modules?

The CPU module is the central control hub of your entire automation stack. Refurbished or pulled processors often suffer from thermal solder cracking, degraded flash memory cells, and worn connector contacts. Sourcing New Surplus guarantees 100% remaining component operational life, original factory timing performance, and zero historical exposure to industrial environments.

What quality control steps are completed on this CPU prior to shipment?

Every undergoes a detailed QC protocol. This includes serial number verification, physical backplane pin inspection, power-on self-test (POST) execution, and live communications testing in a Series 90-30 rack.

What is the key difference between the IC693CPU350 and the ?

While both processors operate at 32 MHz and support up to 8 total racks (2,048 I/O points), the offers 80K Bytes of user memory compared to the 32K Bytes available on the IC693CPU350. This additional memory capacity accommodates significantly larger program logic, extended data tables, and complex math routines.

Can I back up the program logic without relying on the lithium RAM battery?

Yes. The supports writing the user program and system configuration directly to non-volatile onboard Flash memory through Proficy Machine Edition. This guarantees logic preservation during long-term power outages even if the backup battery expires.

What warranty is included with this New Surplus CPU?

This CPU module includes a full 1-year functional warranty. If any operational defect or hardware failure occurs during normal use within 12 months, we will immediately supply a replacement unit from our active buffer inventory.
