GE Fanuc IC695CPE330-ABAF Replacement for PACSystems RX3i

Product Overview

GE Fanuc IC695CPE330-ABAF Replacement for PACSystems RX3i: Seamless Transition & Legacy System Upgrade

The IC695CPE330-ABAF is a high-performance CPU module for the GE Fanuc PACSystems RX3i platform, widely deployed across process automation, discrete manufacturing, power generation, and utility control systems. As GE Intelligent Platforms (now Emerson Automation Solutions) continues to evolve its product roadmap, many facilities operating legacy RX3i racks face the challenge of sourcing reliable, specification-matched replacements for aging or discontinued CPU modules. TOPNLMS stocks the IC695CPE330-ABAF to support exactly this need — providing a verified, tested, and warranty-backed unit that enables a smooth, low-risk migration from older or end-of-life controllers without requiring a full system redesign.

Whether your plant is retiring a Series 90-30 CPU or consolidating multiple legacy racks into a unified RX3i architecture, the IC695CPE330-ABAF integrates directly into the existing IC695CHS016 or IC695CHS012 universal backplane without mechanical modification. The module retains full backward compatibility with RX3i I/O modules, including analog input modules such as the IC695ALG608 and digital output modules such as the IC695MDL754, eliminating the need for rewiring field terminations during the upgrade process.

Seamless Upgrade Solutions

A successful IC695CPE330-ABAF migration rarely involves the CPU alone. In practice, field engineers upgrading from a Series 90-30 or early RX3i system will also evaluate the surrounding infrastructure to ensure the entire control architecture is modernized without introducing new failure points.

On the communications side, the IC695CPE330-ABAF’s dual Ethernet ports natively support SRTP and Modbus TCP, which means existing SCADA or HMI connections using the IC695ETM001 Ethernet module can often be consolidated directly onto the CPU — reducing rack slot consumption and simplifying network topology. For sites still relying on legacy serial fieldbus connections, the IC695CMM002 communications module provides continued RS-232/RS-485 support alongside the new CPU, preserving existing device wiring to RTUs, drives, and third-party instruments.

On the I/O side, most IC695 series analog and digital modules — including the IC695ALG608 8-channel analog input module and the IC695MDL754 32-point 24VDC output module — are fully compatible with the IC695CPE330-ABAF without any configuration changes. For facilities that still operate IC693 series I/O modules in mixed racks, the IC695LRE001 RX3i expansion adapter allows seamless integration, protecting the existing I/O investment during the CPU upgrade phase.

Power supply compatibility is another key consideration. The IC695PSA040 40W AC power supply and the IC695PSD040 DC variant are both fully rated for use with the IC695CPE330-ABAF, and no power budget recalculation is typically required when replacing an equivalent-generation CPU. For installations where the existing power supply is also aging, TOPNLMS recommends sourcing a replacement IC695PSA040 simultaneously to avoid a secondary unplanned outage.

Finally, for commissioning and program transfer, a standard USB-to-mini-USB programming cable compatible with Proficy Machine Edition is all that is required to download the existing ladder logic or structured text program to the new CPU. No hardware key or license transfer is needed for the CPU module itself, significantly reducing the administrative burden of the upgrade.

Retrofit Guidance FAQ

Q: Do I need to rewire field terminals when replacing my existing RX3i CPU with the IC695CPE330-ABAF?
A: No. The IC695CPE330-ABAF is a CPU-slot replacement only. All field wiring connects to I/O modules, not the CPU directly. As long as your I/O modules remain in place, no field wiring changes are required.

Q: Can I reuse my existing Proficy Machine Edition project file?
A: Yes. Projects developed in PME 7.x or later are compatible with the IC695CPE330-ABAF. You may need to update the hardware configuration target in PME to match the new CPU firmware revision, then perform a full download. Logic, variable tables, and HMI tag references are preserved.

Q: What communication protocols does the IC695CPE330-ABAF support natively?
A: The CPU supports SRTP (GE native), Modbus TCP (client and server), EGD (Ethernet Global Data), and standard TCP/IP. OPC-UA connectivity is available via Proficy software integration. Legacy SNP serial protocol is supported via the onboard serial port.

Q: Will the IC695CPE330-ABAF fit in my existing RX3i rack without mechanical modification?
A: Yes. The module occupies a single CPU slot in any IC695CHS012 or IC695CHS016 universal backplane. No additional mounting hardware, brackets, or slot adapters are required.

Q: How do I handle the transition from a Series 90-30 system to the RX3i platform?
A: A Series 90-30 to RX3i migration typically involves: (1) exporting the existing 90-30 program from Proficy ME, (2) creating a new RX3i hardware configuration targeting the IC695CPE330-ABAF, (3) importing and validating the logic, and (4) using the IC695LRE001 adapter if retaining IC693 I/O modules. TOPNLMS can provide pre-shipment functional testing documentation upon request.

Q: What is the physical installation space requirement?
A: The IC695CPE330-ABAF occupies one slot in the RX3i universal backplane. Control cabinet depth requirements are standard for the RX3i form factor (approximately 150mm depth). No additional clearance beyond standard RX3i installation guidelines is needed.

Warranty Assurance

Every IC695CPE330-ABAF unit shipped by TOPNLMS is covered by a 12-month replacement warranty from the date of delivery. Prior to shipment, each unit undergoes a multi-point functional inspection including power-on verification, communication port testing, and firmware version confirmation. Units are shipped in anti-static packaging with full traceability documentation.

In the event of a warranty claim, TOPNLMS provides a direct replacement unit — not a repair-and-return process — to minimize your system downtime. Our average response time for warranty replacement requests is within 2 business days. For urgent plant-down situations, expedited air freight options are available to most global destinations.

TOPNLMS maintains stock of the IC695CPE330-ABAF and related PACSystems RX3i components to support both planned maintenance schedules and emergency breakdown scenarios. All units are sourced through verified supply channels and are not refurbished or reconditioned unless explicitly stated.
