GE Fanuc IC693CPU374 Series 90-30 133MHz Embedded Ethernet CPU

Description

Key Technical Specifications

Product Introduction & Supply Chain Strategy

The GE Fanuc IC693CPU374 is the highest-performing single-slot processor available for Series 90-30 PLCs. Powered by a 133 MHz processor with 240K Bytes of user memory and an integrated 2-port 10/100 Ethernet switch, it delivers sub-millisecond execution speeds and direct network integration without requiring a separate Ethernet module (IC693CMM321).

Securing the IC693CPU374 as New Surplus is a critical supply chain strategy for plant operations running complex Series 90-30 architectures. Sourcing factory-fresh, uninstalled original inventory eliminates the elevated risks of chip thermal degradation, Ethernet port PHY failures, and memory corruption associated with second-hand parts while avoiding multi-million-dollar control system migrations.

Installation & Configuration Guide

Stage 1: Pre-Installation (Prep & Safety)

1. Execute Lock-Out/Tag-Out (LOTO) procedures on the power source supplying the CPU main rack.
2. Put on an anti-static grounded wrist strap to protect sensitive surface-mount Ethernet and processor circuitry from ESD damage.
3. Record or photograph the IP address, subnet mask, and network topology settings from the existing controller prior to removal.

Stage 2: Removal

1. De-energize the baseplate rack power supply and disconnect RJ-45 Ethernet patch cables from the front panel ports.
2. Squeeze the release levers at the top and bottom of the CPU module in Slot 1.
3. Slide the card straight forward from the baseplate connector to protect backplane interface pins.

Stage 3: Installation (Clone & Seat)

1. Position the rear card edge of the replacement IC693CPU374 into Slot 1 of the CPU Main Baseplate (IC693CHS397 or IC693CHS391).
2. Press firmly on the top and bottom face of the module housing until the retaining latches click securely into place.
3. Plug the RJ-45 Ethernet network cables into the front panel ports (PORT 1 / PORT 2).

Stage 4: Power-On & Testing

1. Reapply power to the main rack power supply module.
2. Observe front panel LEDs: confirm that “PWR” and “OK” light solid green, and the Ethernet “LAN” and “LINK” indicators show active green status upon network connection.
3. Connect via Proficy Machine Edition over Ethernet (SRTP) or RS-485 SNP, download/verify system logic and hardware configuration, and set the processor to RUN mode.

Firmware/Software Versions & Upgrade Notes

• Software Compatibility: Requires Proficy Machine Edition (PME) Release 5.0 or higher. Legacy Logicmaster 90-30 software does not natively support Ethernet configuration for the CPU374.
• Firmware Dependencies: Operating system and Ethernet transceiver logic are stored in flash memory. Ensure that replacement modules match or exceed the firmware revision (e.g., Firmware Version 12.0 or higher) required by your program, particularly if utilizing advanced Modbus TCP/IP client/server features.
• Baseplate Restrictions: Must be installed in Slot 1 of a modular CPU main baseplate (IC693CHS397 or IC693CHS391). It cannot be installed in embedded baseplates (such as the CPU311) or expansion chassis.

Frequently Asked Questions (FAQ)

Is this IC693CPU374 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.

Why is purchasing New Surplus critical for high-speed Ethernet CPUs like the IC693CPU374?

The CPU374 generates more internal heat than standard processors due to its high-frequency 133 MHz processor and dual Ethernet transceivers. Refurbished or pulled units frequently suffer from thermal stress fractures on BGA chips, failing PHY transceivers, and degraded RAM retention circuits. Sourcing New Surplus guarantees 100% remaining component lifespan, full signal integrity, and zero prior industrial exposure.

What quality control procedures are completed on this unit prior to shipment?

Every undergoes a comprehensive QC sequence. This includes serial number verification, physical backplane pin inspection, power-on self-test (POST) execution, and live Ethernet communications testing (ping, SRTP handshake, EGD broadcasting) in a Series 90-30 test rack.

What is the advantage of the built-in Ethernet switch on the ?

The integrated 2-port 10/100 Ethernet switch allows daisy-chaining network connections between multiple PLCs or HMI panels without requiring an external industrial Ethernet switch in the control cabinet, saving space and wiring cost.

Can the IP address be assigned without using programming software?

Yes. If temporary address setup is required, the supports IP address assignment via the GE Ethernet SetIP Utility over the network, though permanent IP configuration should always be stored in the hardware project configuration file using Proficy Machine Edition.

What warranty coverage comes with this New Surplus processor module?

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.
