Description
The GE Emerson PACSystems RX3i IC695CPE305 is a high-performance, slot-level central processing unit (CPU) engineered for industrial automation, high-speed machine control, and process optimization applications. Operating on an internal 1.1 GHz Intel Celeron processor with 5 MB of user memory, this controller manages complex logic sequencing, motion control, and multi-protocol network communication. It plugs directly into the RX3i Universal Backplane (PCI-based) to deliver high-speed data throughput and deterministic program execution.

Core Hardware Features & Physical Layout
The front plate of the IC695CPE305 features an array of physical interfaces and status indicators designed for real-time field diagnostics and service access:
- Energy Pack Interface: Accommodates a connection to an external Smart闪存 (SmartFlash) Energy Pack (IC695ACC402). This supercapacitor-based energy source powers the processor long enough to write all volatile RAM variables to non-volatile flash memory during an unexpected power blackout, eliminating the need for lithium backup batteries.
- USB Ports (USB1, USB2): Dedicated Type-A master ports used for firmware updates, logic cloning, and data-logging transfers via standard industrial USB flash keys. Note: These ports are not intended for direct programming connections.
- Serial Comm Port: An isolated RS-232 port utilizing an RJ25 modular connector. It provides direct serial links to legacy HMIs, barcode scanners, or Modbus RTU networks.
Field Integration & Firmware Guardrails
When installing or hot-swapping an IC695CPE305 module into an active RX3i system rack, prioritize the following engineering boundaries:
Firmware Generation Alignment
The PACSystems RX3i platform relies on tightly integrated firmware stacks.
Critical Field Note: Prior to placing a replacement CPU module onto a live production bus, verify its firmware revision using Machine Edition software. If the replacement CPU has firmware version 9.xx pre-installed, but your existing configuration project was compiled under version 7.xx or 8.xx, the backplane will reject the configuration download and flag a “Hardware Configuration Mismatch” error. Use the front firmware update procedure to align the CPU with your existing project standard.
Network Configuration and Security
- IP Address Allocation: The embedded Ethernet port must be assigned a static, un-conflicted IP address within the Machine Edition hardware configuration editor.
- Port Isolation: If the CPU is connected directly to a plant-wide network, disable unused communication servers (such as the legacy SRTP or anonymous FTP services) inside the CPU configuration software to mitigate unauthorized access vectors.
Frequently Asked Questions
Q: Can the IC695CPE305 be installed or extracted while the rack power is turned on?
No. The RX3i system supports Hot-Swapping (Insertion/Extraction Under Power) for standard I/O modules, but this does not apply to the central processing unit. Removing or inserting the CPU module while the backplane is energized can cause localized voltage arcing, which permanently damages the high-speed PCI interface pins on the Universal Backplane or corrupts the internal flash memory sectors.
Q: What does a flashing amber “STSTAT” or “RUN” LED signify on the front display?
A flashing green RUN LED indicates that the CPU has loaded a configuration and is executing logic, but is in an outputs-disabled or test state. A flashing amber STSTAT (System Status) LED points to an active entry inside the Controller Fault Table, such as a low energy-pack charge, a physical I/O module loss, or a software watchdog timer over-run. Connect via Machine Edition and read the fault logs to identify the exact cause.
Q: Does the IC695CPE305 require an external battery to retain its logic program during a shutdown?
No. The CPU utilizes non-volatile flash memory to store the primary control application program and configuration parameters. However, to preserve dynamic registers, system clocks, and historical data tables across a power cycle without a battery, you must deploy the optional external IC695ACC402 Energy Pack. If neither a battery nor an energy pack is present, all variable register data will revert to default factory parameters upon a hard cold restart.
