IC695CPE330 Emerson GE Fanuc PACSystem RX3i CPU Controller Module

Product Overview

The IC695CPE330 is a high-performance Programmable Automation Controller (PAC) CPU module designed by Emerson Automation (formerly GE Fanuc) for the PACSystem RX3i platform. Built upon a 1.6 GHz dual-core processor with a dedicated communications engine, this controller executes complex automation algorithms across high-density industrial applications requiring low-latency synchronization and multi-protocol networking.

Featuring 64 MB of high-speed RAM and 64 MB of non-volatile user flash storage, the IC695CPE330 manages up to 32K discrete and analog I/O points across 8 local racks. It comes equipped with three gigabit RJ-45 Ethernet ports (one independent LAN 1 port and a dual-port embedded switch on LAN 2) alongside a USB 2.0 master port for thumb-drive program deployment and maintenance without a programming PC.

System Architecture & Feature Set

• Dual-Core Processing Architecture
  • Primary 1.6 GHz processor core dedicated exclusively to deterministic logic execution and high-speed scan times.
  • Secondary dedicated communications co-processor handling protocol stacks, OPC UA server sessions, and backplane bus traffic.
• Gigabit Ethernet & Multi-LAN Networking
  • LAN 1 (Single Port): Dedicated RJ-45 10/100/1000M port for high-priority controller-to-controller or SCADA links.
  • LAN 2 (Dual Port Switch): Integrated unmanaged switch ports providing ring or daisy-chain topology options for field devices.
  • Handles up to 48 concurrent SRTP Server connections and 16 Modbus TCP Server sessions (supporting 32 clients per connection).
• High-Availability Redundancy Support
  • Enables bumpless hot-standby CPU failover architectures via PROFINET controllers, Ethernet Global Data (EGD), and Genius I/O networks.
  • Supports external energy backup packs (IC695ACC402 / IC695ACC412) to preserve volatile memory contents during main power disruptions.
• Multi-Language Execution & Protocol Versatility
  • Native support for IEC 61131-3 languages (Ladder Diagram, Structured Text, Function Block Diagram) and embedded C programming.
  • Direct protocol translation for PROFINET, OPC UA, Modbus TCP/RTU, PROFIBUS-DP, DeviceNet, and Reflective Memory (CMX).

Technical Specifications

Diagnostic Capabilities & Operational Status Monitoring

• 6-LED Diagnostic Panel: Real-time visual tracking of CPU status (OK, RUN, DIAG), Ethernet activity (LAN 1/2 LINK/ACT), and battery/capacitor charge states.
• Hardware Run Mode Switch: Physical 3-position toggle switch (RUN W/OUTPUTS, RUN W/O OUTPUTS, STOP) for maintenance override protection.
• OPC UA Embedded Diagnostics: Provides direct telemetry, CPU thermal limits, memory utilization, and communication error rates to higher-tier MES/DCS software.
• USB Firmware & Logic Upload: Enables complete logic backup, restoration, and system event logging via encrypted USB flash drives without software license keys.

Target Application Scenarios & Systems

• High-Speed Packaging Lines: Coordinates motion, servo drives, and vision inspection systems using low-jitter PROFINET IRT communication loops.
• Power Generation & Turbine Control: Executes redundant hot-standby logic failovers across dual-CPU configurations on utility gas and steam turbines.
• Oil & Gas Compressor Racks: Manages distributed I/O blocks over long distances while streaming process variables directly into plant SCADA via OPC UA over Ethernet.

Installation & Rack Configuration Guidelines

• Slot Position Mandate: Must be installed strictly in the main CPU rack (Slot 0/1 area) of an RX3i Universal Backplane (IC695CHS012 or CHS016).
• Energy Pack Wiring: Connect the optional IC695ACC402 capacitor pack using the IC695CBL002 cable to guarantee non-volatile RAM retention upon complete power loss.
• Ethernet Separation: Isolate high-volume SCADA traffic on LAN 1 while using LAN 2 ports for local I/O drop loops to prevent network congestion.

Packaging, Logistics & Warranty Terms

• Dispatch Lead Time: In-stock units ready for immediate warehouse dispatch within 24 to 48 hours.
• Express International Logistics: Priority global shipping provided via DHL Express, FedEx, and UPS.
• Factory Packaging: Supplied 100% Brand New and Original in sealed anti-static factory packaging.
• 12-Month Coverage: Backed by a comprehensive 12-month quality replacement warranty against operational defect.

Engineering Procurement Guide

• Verify Rack Slot Space: Ensure the target backplane has two adjacent open slots, as the module dimensions occupy double slot width.
• Calculate 24VDC Power Requirements: Confirm the main 24VDC system power supply capacity covers the 0.625A current draw of the CPU card along with attached option modules.
• Select Correct Capacitor Pack: Match the CPU with an energy pack if your application requires retaining real-time clock and un-cleared table data during power outages.

Frequently Asked Questions (FAQ)

Q: What occurs if I insert a standard USB drive into the front master port while the controller is running?

A: The CPU detects the storage device without interrupting logic execution, allowing technicians to upload diagnostic logs or trigger pre-configured script downloads.

Q: How does the dual-core architecture prevent high Ethernet network traffic from affecting logic scan times?

A: Network handling runs on a dedicated secondary core, isolating Ethernet packet processing from the main logic execution engine.

Q: Can this controller be installed in an RX3i expansion or remote I/O rack?

A: No, the processor must be situated in the main CPU rack; remote expansion racks require dedicated expansion receiver modules instead.

Q: What is the main operational difference between LAN 1 and LAN 2 on this CPU card?

A: LAN 1 provides a single routed IP address, whereas LAN 2 features an embedded dual-port switch sharing one IP address across two physical ports.

Q: Is an external backup battery mandatory to retain user programs during power loss?

A: No, compiled user programs are saved to 64 MB NVRAM flash storage; the energy pack is only required to preserve unbacked volatile variables and internal clock time.

Global PLC Spare HUB's Insight

During an upgrade at a regional water treatment plant, operators were plagued by intermittent communications drops on their legacy rack CPU during peak polling cycles. The single-core processor was struggling to manage SCADA requests while simultaneously executing complex PID loops for chemical dosing pumps.

Our engineering team recommended upgrading to the IC695CPE330 controller. By segregating the plant SCADA network onto LAN 1 and using LAN 2 for localized PROFINET I/O drops, the plant leveraged the CPU's dual-core design to eliminate communication lag entirely. Logic scan times dropped by over 60%, providing the client with a rock-solid, high-availability control architecture without requiring complete field I/O rewiring.
