GE IC695CPE310 Central Processing Unit – High-Performance RX3i Controller | PACSystems RX3i Platform
Engineering Background
The GE IC695CPE310 is a flagship Central Processing Unit within GE’s PACSystems RX3i automation platform — a successor architecture to the Series 90-30 and Series 90-70 families. Designed for demanding industrial environments, the RX3i backplane leverages a high-speed PCI bus (up to 200 MB/s) to deliver deterministic scan times and seamless I/O expansion. The CPE310 represents GE’s commitment to open-architecture control: it runs standard IEC 61131-3 programming languages and integrates natively with Proficy Machine Edition (PME) software.
Product Positioning
The IC695CPE310 targets mid-to-large scale process and discrete manufacturing applications where high memory capacity, dual-port Ethernet connectivity, and backward compatibility with legacy GE I/O are non-negotiable. It is the preferred CPU for engineers migrating from Series 90-70 systems while retaining existing field wiring and I/O modules.

- USB Programming Port: Direct laptop connection without a serial adapter — accelerates commissioning and on-site troubleshooting.
- Backward I/O Compatibility: Accepts legacy Series 90-30 I/O modules via IC694 adapter, protecting existing field wiring investments.
- Hot-Standby Redundancy Ready: Supports CPU redundancy configurations with IC695RMX128 redundancy memory xchange module.
- IEC 61131-3 Multi-Language: Engineers can mix LD, FBD, ST, and SFC within a single project — maximizing code reuse and team flexibility.
- Proficy Machine Edition Integration: Full support for online editing, force tables, data logging, and motion coordination within PME.
System Architecture & Signal Flow
The IC695CPE310 occupies Slot 0 of the RX3i main backplane. On power-up, the CPU performs a self-diagnostic sweep, initializes the PCI bus, and establishes Ethernet link states before entering RUN mode. Program execution follows a deterministic scan cycle:
- Input Scan: All discrete and analog input values are read from I/O modules into the CPU’s input image table.
- Logic Solve: The user program executes sequentially (or in task-scheduled blocks for SFC/FBD).
- Output Scan: Solved output values are written from the output image table to I/O modules.
- Communications Window: Ethernet, serial, and backplane communication requests are serviced.
- Housekeeping: Diagnostics, watchdog timer reset, and memory integrity checks.
Ethernet Port 1 is typically assigned to the plant LAN (SCADA/HMI), while Ethernet Port 2 is used for CPU-to-CPU peer communications or isolated programming network — both operate independently with separate IP addresses.

Technical FAQ
Q: Is the IC695CPE310 compatible with Series 90-30 I/O modules?
A: Yes, via the IC694ALG220 or equivalent adapter modules that allow Series 90-30 I/O to mount in RX3i expansion racks.
Q: Can I use both Ethernet ports simultaneously?
A: Yes. Both ports are independent with separate IP addresses and MAC addresses. They can be on different subnets simultaneously.
Q: What programming software is required?
A: GE Proficy Machine Edition (PME) version 8.0 or later is recommended. The USB port enables direct connection without a serial-to-USB adapter.
Q: Does this CPU support CPU redundancy?
A: Yes, when paired with the IC695RMX128 Redundancy Memory Xchange module and a redundant power supply configuration.
Q: What is the maximum number of I/O points supported?
A: The RX3i system supports up to 8,192 discrete I/O points and 2,048 analog I/O channels across all racks.
Q: Is firmware upgrade possible in the field?
A: Yes. Firmware can be updated via USB or Ethernet using PME’s firmware upgrade utility without removing the module from the rack.
Q: What happens to the program if power is lost?
A: The IC695CPE310 uses non-volatile flash memory to retain the user program. A supercapacitor maintains RAM data (timers, counters, retentive registers) for a limited period during power loss.
