GE Fanuc IC695CPU315-CD RX3i High Performance CPU Module

Description

Product Introduction

The GE Emerson PACSystems RX3i IC695CPU315-CD is a high-capacity, 1 GHz central processing unit engineered for large-scale, complex automation processes. Featuring an impressive 20 MB of user memory, this processor allows plant engineers to execute extensive application code, handle massive data logging arrays, and process high-speed PID loops without running into memory bottlenecks or scan-time delays.

Occupying a double-slot footprint on an RX3i Universal Backplane (IC695CHS012 or IC695CHS016), the IC695CPU315-CD connects directly to the system’s high-speed PCI bus. It includes onboard RS-232 and RS-485 serial interfaces for direct programmer access or legacy device handshaking. The “CD” hardware revision reflects upgraded internal component architecture, ensuring long-term hardware stability in high-vibration and electrically noisy industrial environments.

Key Technical Specifications

Application Scenarios & The “Trench” Experience

When a main processing card suffers internal memory degradation or a backplane communication lockup, an entire production floor comes to an immediate halt. Downtime mounts every minute while technicians scramble to source a compatible high-capacity CPU with matching firmware revisions.

• Power Plant Balance-of-Plant (BOP) – Running multi-boiler sequence logic, turbine interlocks, and managing thousands of field sensor points across continuous polling loops.
• Large Automotive Body Shops – Coordinating high-density robot cell interlocks, safety zones, and conveyor tracking algorithms across multi-rack RX3i architectures.
• Pharmaceutical Batching Systems – Storing extensive batch recipes, multi-stage sequencing logic, and real-time audit trails requiring maximum onboard memory headroom.

Field Case Study: A continuous pharmaceutical batch plant experienced a fatal system fault when an old CPU failed during a routine program update, stranding two active 5,000-gallon batch reactors. The plant couldn’t afford a long outage. Swapping in an IC695CPU315-CD, verifying the hardware revision compatibility, and loading the project backup via PAC Machine Edition restored 20MB of logic processing in under 25 minutes—saving over $120,000 in raw chemical inventory from spoiling.

Transparency SOP: Quality Assurance & Testing

We understand that placing a high-capacity CPU back into a mission-critical control architecture requires 100% confidence. Every IC695CPU315-CD undergoes a rigorous diagnostic protocol on our live testing rigs before it leaves the bench.

1. Inbound Mechanical Check: Inspect double-slot housing tabs, PCI backplane edge pins, battery connection terminals, and OEM serial labels for hardware revision “CD”.
2. Backplane & Boot Sequence: Mount the CPU into an RX3i Universal Baseplate (IC695CHS012) powered by an IC695PWR330. Verify clean boot-up sequence and LED indicators (OK, RUN, FAULT, STAT).
3. PME Software Diagnostics: Establish communication via PAC Machine Edition (PME), clear diagnostic fault tables, test flash memory sectors, and document firmware revs.
4. Full Memory Load Test: Download a 20MB maximum-capacity stress program. Force high instruction-count loops to verify processing stability and exercise RS-232/RS-485 serial ports under full communication traffic.
5. ESD Safe Packaging: Install a protective cover over the backplane edge connector, seal in anti-static shielding bags with fresh desiccant, and box with custom dense foam packaging.

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

⚠️ Note the Double-Slot Footprint! Unlike single-slot CPUs like the CPE305, the IC695CPU315-CD requires two physical slots on your RX3i Universal Backplane (IC695CHS012/016). Make sure your cabinet layout has enough slot clearance next to the power supply module before installation!

❗ Verify Backplane Slot Type! This module MUST be installed in an RX3i Universal Backplane that supports PCI bus communication. It will NOT work in expansion baseplates (IC694CHS392/398) or legacy Series 90-30 racks.

⚠️ Watch Your Hardware Revision Compatibility! The “-CD” suffix indicates a specific hardware revision level. In certain redundant or high-availability rack setups, mixing different CPU hardware revs (e.g., pairing a CPU315-CA with a CPU315-CD) can cause synchronization failures during boot or redundancy handshakes. Ensure both main and backup racks match.

Frequently Asked Questions (FAQ)

Q: Does the IC695CPU315-CD have built-in Ethernet ports?

he includes onboard RS-232 and RS-485 serial ports, but no direct RJ-45 Ethernet connection. To add Modbus TCP, PROFINET, or SRTP Ethernet communication to your RX3i system, add an expansion Ethernet module such as the IC695ETM001 or IC695PNC001.

Q: What is the main difference between the IC695CPU310 and ?

A: The IC695CPU310 features 10 MB of user memory, whereas the doubles that capacity with 20 MB of user memory, making the CPU315 better suited for very large control projects with high variable tags and recipe storage.

Q: Can I replace an older -AB or -BC with this -CD revision?

A: Yes. In standard non-redundant applhe is fully backward compatible with older revision levels. Simply download the original project from PAC Machine Edition to the replacement unit.

Q: How is the memory bache when power is turned off?

A: The module relies on either a plug-in lithium battery (IC698ACC701 / IC693ACC302) or an optional RX3i Energy Pack (IC695ACC402) to retain user program RAM and register data during panel power shutdowns.

Q: What warranty is provided with this unit?

A: Every new surplus and fully bench-tesed module shipped from our facility comes backed by a full 12-month replacement warranty.
