Product Introduction & Supply Chain Strategy
The GE Fanuc IC693CPU350 is a high-performance, single-slot modular processor designed for Series 90-30 PLC systems. Built on a 32 MHz 80386EX processor with 32K Bytes of user memory, it delivers fast scan execution, expanded register capacity, and multi-rack communication control for mid-to-large industrial automation applications.
Securing this modular CPU as New Surplus provides an vital supply-chain safety buffer against sudden control system failures. Sourcing factory-fresh, unused inventory eliminates the elevated risks of memory corruption, timing jitter, and hardware degradation common in second-hand parts pulled from decommissioned sites.

Installation & Configuration Guide
Stage 1: Pre-Installation (Prep & Safety)
- Perform strict Lock-Out/Tag-Out (LOTO) procedures on the power supply feeding the main CPU baseplate.
- Put on a grounded anti-static wrist strap before handling the IC693CPU350 to guard against static damage to high-density memory chips.
- Verify that a fresh RAM backup battery (IC693ACC301) is installed in the power supply module to ensure project configuration retention.
Stage 2: Removal
- Turn off power to the baseplate and disconnect any serial communication cables attached to the power supply.
- Depress the top and bottom module retention latches on the existing CPU module installed in Slot 1.
- Pull the card straight outward from the baseplate connector to avoid bending backplane interface pins.
Stage 3: Installation (Clone & Seat)
- Align the rear card-edge guide of the replacement IC693CPU350 with Slot 1 on the CPU Main Baseplate (IC693CHS397 or IC693CHS391).
- Press firmly on the top and bottom of the module housing until the retaining latches click securely into the chassis rail.
- Verify that the keying pins on the backplane match the module connector to ensure correct seating.
Stage 4: Power-On & Testing
- Reapply 120/240V AC or 24V DC input power to the main rack power supply module.
- Observe the front panel status indicators: verify that the “PWR” and “OK” LEDs light solid green, confirming self-diagnostic completion.
- Connect via Proficy Machine Edition or Logicmaster 90 using an RS-485 SNP interface cable, upload the hardware configuration, and switch the CPU state to 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 IC693CPU350 uses flash-based operating system firmware. Ensure replacement cards match or exceed the firmware version (e.g., Firmware 10.0 or higher) required by your project logic, especially if utilizing advanced PID blocks or Ethernet Option Modules (IC693CMM321).
- Baseplate Restrictions: Must be installed in Slot 1 of a modular CPU baseplate (IC693CHS397 or IC693CHS391). It cannot be installed in embedded CPU baseplates (such as the IC693CPU311) or expansion baseplates.
Frequently Asked Questions (FAQ)
Is this IC693CPU350 processor brand new or a refurbished card?
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.
Why is purchasing New Surplus critical for central CPU modules?
The central processor is the most critical single point of failure in any PLC system. Refurbished or pulled CPUs frequently harbor thermal fatigue on solder joints, degraded flash memory cells, and worn backplane connectors. Investing in New Surplus guarantees 100% remaining component operational life, original factory timing tolerances, and zero prior environmental stress.
What quality assurance testing is completed on this CPU before shipping?
Every undergoes a thorough inspection protocol. This includes anti-counterfeit serial checks, backplane connector pin checks, power-on self-test (POST) validation, and full memory/SNP communication testing in a Series 90-30 rack.
What is the primary difference between the and lower-tier CPUs like the CPU331 or CPU341?
The operates at 32 MHz (compared to 16 MHz or 20 MHz on lower models), offers 32K Bytes of user logic memory, supports floating-point math functions, and can address up to 8 total racks (2,048 I/O points), making it suitable for larger, faster process applications.
Can I backup my user logic to non-volatile memory without relying on the battery?
Yes. The supports writing the user program and configuration data directly to onboard Flash memory using Proficy Machine Edition. This ensures logic retention even if the primary RAM battery fails during extended plant shutdowns.
What warranty coverage is provided 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 provide a replacement unit from our buffer stock.
