Description
Product Introduction & Engineering Value
When multi-axis motion control, dense analog monitoring, and plant-wide Ethernet communications collide on a single control rack, underpowered processors choke on scan times. The GE PACSystems RX3i IC695CPE310-ACAT handles heavy computational loads with ease, using a 1.1 GHz Intel Atom engine backed by 10 MB of battery-buffered execution memory.
Equipped with dynamic memory allocation, dual dual-stack Ethernet ports, and high-speed PCI backplane throughput, this CPU processes thousand-loop logic programs in milliseconds. It allows control engineers to seamlessly bridge legacy Series 90-30 I/O architectures with modern PROFINET remote drops without sacrificing deterministic performance or processor scan consistency.

Field Application & The “Trench” Experience
The Trench Story: A grain terminal’s main elevator PLC locked up during harvest season after an power surge corrupted the CPU memory. The local technician swapped in our pre-tested IC695CPE310-ACAT, inserted the plant’s backup SD memory card, and restored the full 8MB logic program and IP network map in under 10 minutes. The dual Ethernet ports immediately re-established deterministic communications with 14 remote I/O drops, getting the grain legs moving before trucks backed up into the highway.
- High-Speed Material Handling Systems: Managing complex high-density conveyor routing matrices and high-speed sorters requiring sub-millisecond scan resolution.
- Continuous Chemical Processing Units: Executing hundreds of continuous PID loops across multi-stage distillation and reaction vessels.
- Power Generation Control Panels: Synchronizing turbine generator speed signals and breaker trip interlocks via real-time Modbus TCP telemetry.
Transparency SOP: QA & Testing
- Visual & Port Mechanics Check: Thorough inspection of card-edge PCI connectors, front RJ-45 retention clips, serial pins, and housing latch assemblies.
- Backplane & Power-Up Diagnostics: Installation into an IC695CHS012 universal rack to verify boot sequence, internal self-tests, and
STAT,OK, andCONFIGLED states. - Firmware & Memory Integrity Audit: Flashing baseline firmware revision, verifying full 10 MB RAM address accessibility, and testing non-volatile memory backup functions.
- Communications Load Stress Test: Simultaneous high-bandwidth traffic testing across both embedded Ethernet ports using SRTP and Modbus TCP protocols to confirm zero packet drop under load.
- Logic Execution & I/O Loop Test: Running a multi-thousand-step test project driving digital and analog I/O cards to confirm scan speed performance and PCI backplane bus timing.

The Veteran’s Tech Trap Guide
⚠️ Energy Cell vs. Battery Selection: The IC695CPE310 utilizes a RAM memory backup cell (IC695ACC302 or Smart Energy Cell). If you power down the rack without a healthy energy cell connected, your user memory and RAM-stored register tables (%R) will wipe clean back to factory default on reboot. Always check the battery LED status before shutting down panel power for maintenance!
⚠️ Hardware Revision & Firmware Compatibility: Pay close attention to the revision suffix (e.g., -ACAT). Updating your project in PAC Machine Edition to a higher target CPU revision than the physical module’s installed firmware will block program downloads. Always verify your PAC Machine Edition hardware catalog matches the CPU’s firmware build.
PRO TIP: If you cannot establish a connection over the embedded Ethernet ports after swapping CPUs, the module may be configured with a static IP address from a previous installation. Use the front RS-232 serial port or PAC Machine Edition’s Ethernet Set IP tool over a direct MAC address broadcast to reassign the IP before placing it on the plant network.
Dynamic FAQ
Q: Does the IC695CPE310-ACAT require a separate Ethernet module to communicate over Modbus TCP?
A: No. The features two embedded Ethernet ports directly on the CPU front panel, supporting SRTP, Modbus TCP Server/Client, and Ethernet Global Data (EGD) natively without needing an extra IC695ETM001 card.
Q: Can I use this CPU in older Series 90-30 baseplates?
A: No. The is an RX3i module that requires a PACSystems RX3i Universal Baseplate (such as the IC695CHS012) with PCI backplane connections. However, it can control legacy Series 90-30 I/O modules plugged into the same RX3i universal rack.
Q: How is my program retained during a prolonged plant shutdown?
A: You can write the active project directly to the CPU’s internal non-volatile Flash memory. When configured to load from Flash on power-up, the controller restores your logic and initial values even if the backup battery drains completely.
Q: What condition are your surplus processors in?
A: All of our New Surplus and Refurbished CPUs undergo rigorous multi-step diagnostic testing (including full memory audits, communications stress tests, and physical inspections) and are backed by a complete replacement warranty in anti-static protective packaging.
