GE Fanuc IC695CPE305 RX3i Programmable Automation Controller CPU

Description

Product Introduction

The GE Emerson PACSystems RX3i IC695CPE305 is a high-speed, 1.1 GHz central processing unit designed to serve as the brain of PACSystems RX3i control architectures. Built around a high-performance AMD Geode microprocessor with 5 MB of user memory, this CPU executes complex control logic, advanced math functions, and multi-axis motion algorithms at blistering speeds.

Occupying a single slot on an RX3i Universal Backplane (IC695CHS012 or IC695CHS016), the IC695CPE305 leverages a high-speed PCI backplane architecture for rapid data exchange with I/O and communication modules. It features built-in RS-232 and RS-485 serial communication ports, making it a reliable, standalone controller for standalone machine control or distributed plant setups where dedicated Ethernet cards (like the IC695ETM001) are added for networking.

Key Technical Specifications

Application Scenarios & The “Trench” Experience

When a main CPU locks up or suffers flash memory corruption during a plant-wide power cycle, the entire process drops dead. No logic runs, field networks lose master polling, and operators face immediate downtime costs while waiting for a controller replacement.

• High-Speed Packaging Lines – Managing complex motion profile timing, high-speed registration, and sorting routines across multiple station racks.
• Chemical Batch Reactor Systems – Executing large-scale sequential function charts (SFCs), continuous PID loop control, and historical alarm logging.
• Material Handling & Stacking – Serving as the central logic master for automated storage and retrieval systems (ASRS) communicating via serial encoders.

Field Case Study: A plastic extrusion facility experienced a power spike that killed the CPU on their primary RX3i control rack, locking up the temperature zones and die positioning logic. With no spare on the shelf, the line sat idle for hours. Swapping in an IC695CPE305, popping in the original energy pack/battery, and re-downloading the PAC Machine Edition project restored full 1.1 GHz logic processing in under 20 minutes, preventing raw material from hardening inside the barrel.

Transparency SOP: Quality Assurance & Testing

CPU modules require far more than a simple power-on check. Our automation technicians put every IC695CPE305 through full hardware and firmware diagnostics before clearing it for shipment.

1. Inbound Mechanical Inspection: Inspect PCI edge connector contacts, battery connector pins, terminal retention clips, and OEM serial tags.
2. Backplane & Boot Diagnostics: Mount the CPE305 into an RX3i Universal Backplane (IC695CHS012) powered by an IC695PWR330. Verify clean boot sequence and diagnostic LED behavior (OK, RUN, FAULT).
3. PME Software Handshake: Connect via PAC Machine Edition (PME), clear hardware error logs, verify flash memory integrity, and log the exact firmware version.
4. Logic Stress & Communication Test: Download a 100% memory-capacity stress program. Cycle logic execution, verify RS-232/RS-485 port handshaking under Modbus RTU traffic, and test battery hold-up performance.
5. Anti-Static Packaging: Install a protective cover over the backplane edge connector, seal in an ESD-shielded bag with fresh desiccant, and box with custom dense foam packaging.

The Veteran’s Tech Trap Guide (Crucial Value-Add)

⚠️ This CPU Requires a PCI Slot on a Universal Backplane! The IC695CPE305 uses the high-speed PCI bus connector on RX3i Universal Baseplates (IC695CHS012 or IC695CHS016). It CANNOT be plugged into expansion baseplates (IC694CHS392/398) or legacy Series 90-30 baseplates.

❗ Check Firmware Compatibility with Your PME Software Version! Before downloading your program to a replacement CPE305, verify its firmware revision level. If your project file was created in an older version of PAC Machine Edition, you may need to upgrade/downgrade the CPU firmware via the GE Firmware Upgrade Tool to avoid communication mismatch errors.

⚠️ Don’t Forget to Reconnect or Replace the Memory Battery! The 5 MB user RAM on the CPE305 requires a healthy lithium battery module or Energy Pack to retain the program and register values when system power is removed. If the “BAT” LED turns amber on startup, replace the battery immediately before cycling panel power!

Frequently Asked Questions (FAQ)

Q: Does the IC695CPE305 have built-in Ethernet ports?

A: No. The provides RS-232 and RS-485 serial ports onboard, but it does NOT have built-in Ethernet ports. To add Modbus TCP or SRTP Ethernet communication to your RX3i rack, you must install an expansion Ethernet module like the IC695ETM001.

Q: What is the difference between the and IC695CPE310?

A: The features a 1.1 GHz processor with 5 MB of user memory and occupies a single slot. The IC695CPE310 offers 10 MB of user memory for larger control projects requiring higher data array storage.

Q: Can I hot-swap the CPU module?

A: No! You must NEVER remove or insert the main CPU module while power is applied to the RX3i backplane. Doing so will disrupt logic execution instantly and risks damaging the backplane PCI bus.

Q: What battery does the use?

A: It uses the standard RX3i CPU lithium battery assembly (such as IC698ACC701 or IC693ACC302) or an optional RX3i Energy Pack (IC695ACC402) for maintenance-free RAM retention.

Q: What warranty is included with this CPU?

A: Every new surplus and fully bench-tested pre-owned controller shipped from our facility comes backed by a full 12-month replacement warranty.
