GE Fanuc IC698CPE030-GJ RX7i High-Performance Central Processor

Description

Product Introduction

The GE Fanuc PACSystems RX7i IC698CPE030-GJ is a flagship, high-performance central processing unit engineered to serve as the master controller for demanding, high-density industrial automation applications. Built on the open VME64 backplane standard, the RX7i platform serves as the migration bridge for legacy Series 90-70 VME systems, allowing plants to upgrade to the high-speed PACSystems control engine while retaining existing field-proven VME I/O hardware.

Powered by a 700 MHz Intel Pentium III processor and equipped with 64 Megabytes of battery-backed user RAM along with 64 Megabytes of non-volatile Flash memory, the IC698CPE030-GJ easily handles intensive floating-point math, multi-axis motion synchronization, and complex batch sequencing. The “-GJ” revision designation reflects updated hardware components and firmware enhancements over earlier revisions (such as -AA through -FH). It features two built-in 10/100 Ethernet ports supporting Modbus TCP and SRTP, as well as three RS-232/RS-485 serial ports for seamless communication across plant networks.

Key Technical Specifications

Application Scenarios & The “Trench” Experience

When a high-tier controller like the CPE030 drops offline, entire processing cells or multi-rack control topologies lose synchronization. Because the CPE030 often sits at the head of large-scale chemical reactors, power plants, or rolling mills, a CPU failure stops production immediately.

• Power Generation & Turbine Governor Control – Executing rapid-response trip logic, speed matching, and generator synchronization algorithms.
• Large Water/Wastewater Master Control – Functioning as the master supervisory PLC polling dozens of distributed RX3i, Series 90-30, and Genius I/O nodes via Ethernet.
• Metals & Continuous Casting Lines – Managing real-time closed-loop position and pressure regulation across heavy hydraulic press rolls.

Field Case Study: A continuous chemical processing facility suffered a fatal CPU hardware lockup on an older IC698CPE010 processor due to scan-time overruns following a plant expansion. Upgrading to the 700 MHz IC698CPE030-GJ slashed total execution scan times from 38 ms down to 8 ms, clearing scan-interrupt faults and allowing engineers to re-establish Modbus TCP communication across 22 remote drops without adding external Ethernet coprocessors.

Transparency SOP: Quality Assurance & Testing

Testing high-speed PACSystems RX7i VME CPUs requires a dedicated RX7i chassis, active VME backplane handshakes, and simultaneous multi-port network stress testing.

1. Inbound Mechanical Inspection: Inspect VME gold backplane pins, faceplate insertion/ejection levers, RJ-45 port contacts, and confirm OEM serial/revision tags.
2. Backplane Boot & POST Check: Mount in Slot 1 of an RX7i test rack, verify Power-On Self Test (POST) LED sequences, and clear fault tables using PAC Machine Edition.
3. RAM & Flash Stress Test: Load a full 64MB diagnostic routine across both CMOS RAM and non-volatile Flash, validating memory retention across multiple simulated power cycles.
4. Multi-Port Communication Test: Run continuous full-duplex traffic across both embedded Ethernet ports and all three serial channels under 100% CPU scan load.
5. ESD Packaging & Battery Prep: Disconnect the lithium battery during transport to prevent battery drain, wrap in an ESD shielding bag, and package inside custom dense foam boxes.

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

⚠️ Slot 1 Installation Requirement: The IC698CPE030-GJ MUST be installed into Slot 1 (the leftmost slot) of the primary RX7i rack (IC698CHS017). Installing it in any other slot or expansion chassis will prevent system boot and VMEbus arbitration.

❗ Battery Connection & Memory Protect: The CPE030-GJ relies on a front-mounted lithium battery assembly to retain CMOS RAM memory during power loss. Always verify that the battery lead is securely plugged into the module housing and the front-panel Memory Protect switch is managed correctly before downloading your PAC Machine Edition project.

⚠️ PAC Machine Edition (PME) Hardware Definition: When upgrading from an older revision or smaller CPU (such as a CPE010 or CPE020), ensure your PME software target configuration is updated to the IC698CPE030 hardware profile (Revision GJ). Down-level CPU target definitions will cause configuration download mismatches or prevent proper Ethernet port initialization.

Frequently Asked Questions (FAQ)

Q: What is the main difference between the IC698CPE020 and the IC698CPE030-GJ?

A: The IC698CPE030-GJ features a much faster 700 MHz Pentium III processor and 64 MB of RAM/Flash memory, compared to the CPE020 which utilizes a 300 MHz Celeron processor and 10 MB of RAM/Flash memory.

Q: Can the host legacy Series 90-70 VME cards in the same rack?

A: Yes. The PACSystems RX7i architecture is built on the VME standard, allowing legacy Series 90-70 discrete, analog, and specialty VME cards to run in the same chassis alongside the CPE030-GJ.

Q: What programming software is used for the ?

A: Programming and hardware configuration are performed using Emerson / GE PAC Machine Edition (PME) Logic Developer – PLC software.

Q: Is the hot-swappable?

A: No. RX7i VME racks do NOT support hot-swapping CPU modules. Always disconnect main power to the rack chassis before inserting or removing the processor card.

Q: What warranty is provided with this CPU module?

A: All new surplus and bench-tested pre-owned modules supplied from our stock carry a full 12-month replacement warranty.
