Product Description

The IC695CPE310 is a CPU in the GE Fanuc PACSystem RX3i Series.  The CPU can  perform real-time control of machines, processes, and  material handling systems. It communicates with I/O and Intelligent Option modules over a dual-purpose PCI and serial backplane. 


IC695CPE310  has a 1.1 GHz Atom processor and 10 MB of memory. Its embedded Ethernet interface accommodates two connections rated for 10Mb/sec and 100Mb/sec. It also has RS-485 and RS-232 serial ports. The module supports up to 512 program blocks, each of which can be as large as 128 KB. IC695CPE310 comprehends the Modbus RTU Slave, SNP, and Serial I/O protocols, while using the SNP protocol to communicate with human-machine interface (HMI) devices.


You can program the IC695CPE310 in Ladder Diagram, Structured Text, C, or Function Block Diagram programming languages. Labeled LED indicators on the unit housing can be green, red, off, or blinking when the unit is powered up. This makes troubleshooting efficient, and lets you verify system status at a glance.


IC695CPE310 can be installed in any pair of slots in the main RX3i controller rack except for the slots with the two highest numbers on them.


The processor in IC695CPE310 is approximately three times faster than the  300 MHz Celeron processor in the  otherwise-similar model C695CPU310 . You can upgrade from CPU310 to CPE310 without changing legacy PME software. Please note that if you do decide to upgrade to CPE310 from CPU310, then the RS-232 port on CPE310 does not provide 5V power on pin 5.

Technical Specifications

Processing Speed: 1.1 GHz
CPU Memory: 10 Mbytes
Floating Point: Yes
Power Requirements:   3.3 VDC, 5 VDC or 24 VDC
Serial Protocols: Modbus RTU Slave, SNP Slave, Serial I/O
Embedded Comms: RS-232, RS-485


The IC695CPE310 CPU module is a GE Fanuc CPU from the RX3i PACSystems product line. Its processor is an Atom processor that has a maximum processing speed of 1 GHz. The IC695CPE310 CPU module comes with both SRAM and Flash memory, and it can store program data in its 10 MB uf user memory. The power requirements of the IC695CPE310 CPU module include 1 Amp of current at a backplane voltage rating of 3.3 Volts DC or 5 Volts DC, and 0.5 Amps at a backplane voltage rating of 24 Volts DC. When the RX3i PACSystems IC695CPE310 CPU module is installed in a complete RX3i PACSystems machine control system, it must be installed in the system’s central universal backplane. This CPU cannot function properly if it is installed in an expansion backplane or a remote backplane.


The GE Fanuc IC695CPE310 CPU module from the RX3i PACSystems series comes with a real-time clock that is battery backed. It can also back up its data dynamically. One of the ports on the IC695CPE310 CPU module is a USB port that is a Type A 2.0 master USB port which can be used for configuring the CPU’s applications and also for downloading the application data. It can support 2 Ethernet programmer connections at a time. The 2 serial ports on the IC695CPE310 CPU module are an RS-485 serial port and an RS-232 serial port. The serial protocols that this CPU module supports are the SNP Slave protocol, the Serial I/O protocol, and the Modbus RTU Slave protocol.

Technical Information


Memory retention

The non-volatile storage (NVS) can retain data indefinitely without loss of data integrity. When CPU power is restored, data stored in NVS is transferred back to user memory and the NVS is cleared.

An optional IC695ACC400 Energy Pack powers the CPU long enough to write its user memory contents to non-volatile storage during a system power loss. For details on the Energy Pack, refer to publication GFK-2724.

Program storage

10 Mbytes of non-volatile flash user memory.

Power requirements, nominal

+3.3 VDC: 1.0 A

+5 VDC: 1.0 A (up to 1.5 A if USB is fully loaded with 0.5 A)

+24 VDC: 0.5A at startup, 0.1 A during run time (Applies only if Energy Pack is connected to the CPE310.)

Operating Temperature

0 to 60°C (32°F to 140°F)
