GE IC695CPU320 – High-Performance Dual-Core CPU Module | PACSystems RX3i Platform
Engineering Background: The GE IC695CPU320 is a flagship CPU module within GE Automation’s PACSystems RX3i control platform — a unified, scalable architecture designed for demanding process and discrete manufacturing environments. Built on a 320 MHz dual-core processor with 64 MB of user RAM, this module delivers the computational headroom required for complex ladder logic, function block diagrams, and structured text programs running simultaneously across multi-rack configurations.
Product Positioning: Targeted at procurement engineers and system integrators sourcing a proven, high-availability CPU for new installations or legacy RX3i system expansions, the IC695CPU320 is the preferred choice where deterministic scan times, large program memory, and Ethernet-native communications are non-negotiable requirements.

Engineering Advantages
- Dual-Core Architecture: Separates communication processing from logic execution — eliminates scan-time jitter caused by network traffic spikes.
- Large Memory Footprint: 64 MB RAM supports programs exceeding 32,000 rungs with extensive data logging without external memory expansion.
- Hot-Standby Redundancy Ready: Pairs with IC695RMX128 redundancy module for bumpless switchover in critical process applications.
- Native Ethernet I/O: Supports distributed I/O over Ethernet without additional communication modules, reducing BOM cost.
- Backward Compatibility: Accepts Series 90-30 and VersaMax I/O modules via adapter racks, protecting legacy investments.
- Field-Upgradeable Firmware: Reduces maintenance downtime — no module swap required for firmware updates.
System Architecture & Signal Flow
The IC695CPU320 occupies Slot 0 of the RX3i Universal Backplane. The dual-core processor allocates Core 1 exclusively to deterministic PLC scan execution (logic solve, I/O update, diagnostics) while Core 2 manages all Ethernet communications, EGD publishing, and HMI data serving. This architecture ensures that a burst of SCADA polling or historian queries does not extend the PLC scan cycle.
I/O data flows from field devices → RX3i I/O modules → backplane bus → CPU RAM → logic solver → output update → field actuators. Remote I/O racks communicate via the embedded Ethernet ports using EGD or Profinet (with IC695PNC001 adapter). The CompactFlash slot provides non-volatile recipe storage, data logging, and firmware staging.

Technical FAQ
Q: Is the IC695CPU320 compatible with PACSystems RX7i backplanes?
A: No. The IC695CPU320 is designed exclusively for RX3i Universal Backplanes (IC695CHS series). For RX7i applications, refer to IC698CPE020 or IC698CPE030.
Q: Can this CPU run redundancy without additional hardware?
A: Hot-standby redundancy requires the IC695RMX128 Redundancy Memory Xchange module and a dedicated fiber link between the primary and secondary CPU racks.
Q: What programming software is required?
A: GE Proficy Machine Edition (PME) v8.0 or later is required. PME supports all IEC 61131-3 languages and online editing.
Q: Is firmware upgrade included?
A: Units ship with the firmware version as received. We can pre-flash to a specified firmware version upon request at no additional charge.
Q: Do you provide export documentation for customs clearance?
A: Yes. We provide commercial invoice, packing list, certificate of origin, and ECCN classification documentation for all international shipments.
