Product Description

The IC695CPU310 is a 300 MHz Central Processing Unit from the GE Fanuc RX3i Series. The IC695CPU310 has an Intel Celeron (Pentium III) microprocessor with 10 MB of RAM and 10 MB of flash storage. It also has a pair of embedded serial ports for RS-232 and RS-485 communications. Both ports face front on the chassis for easy access. The IC695CPU310 supports three different serial protocols (Modbus RTU Slave, SNP, and Serial I/O), all of which work with programmable logic controllers to structure the ways in which PLCs supply information: IC695CPU310 uses the SNP Slave protocol to communicate with HMI (human machine interface) devices.


Eight LEDs on the face of the chassis let you see system status at a glance, so that you can tell whether the CPU, battery, and communications channels are working as expected. Product documentation reminds you of what LED colors and states mean, but the CPU follows widely accepted conventions: blinks or red lights indicate system faults, while steady green indicates normal operations.


Dual backplane bus architecture supports RX3i PCI and GE Fanuc Series 90-30-style serial bus usage. The CPU itself supports up to 512 program blocks, each with a maximum size of 128 KB. You can program it in the Ladder Diagram, Structured Text, or Function Block Diagram programming languages. You can also program it in C.


RX3i CPUs are programmed and configured by the programming software to perform real-time control of machines, processes, and material handling systems. 

Technical Specifications

Processing Speed: 300 MHz

The IC695CPU310 module is a CPU module manufactured by GE Fanuc Automation as part of the RX3i PACSystems product line. It supports installation in the 16-slot or 12-slot RX3i universal backplane. This module operates at a current rating of 1.25 Amps at a voltage rating of 3.3 Volts DC, and at a current of 1 Amp at 5 Volts DC. It has an operational temperature range from 0 to 60 degrees Celsius, and it comes with battery-backed RAM with a capacity of up to 10 MB and non-volatile flash memory of 10 MB. The GE Fanuc IC695CPU310 CPU module supports the floating-point data format, and it has a typical execution speed of 0.195 milliseconds/1000 Boolean instructions. This unit comes with an internal daytime clock with a drift of 2 seconds per day at maximum. The elapsed time clock has an internal timing accuracy of 0.01 percent at maximum.

The GE Fanuc IC695CPU310 CPU module supports RS-232/RS-485 interfaces, and it also supports the Serial I/O, Modbus RTU slave, and SNP serial communications protocols. It is well matched and usable with the GE Series 90-30 serial backplane and with the RX3i PCI backplane. The IC695CPU310 CPU module is engineered so that it is electrically compliant with the PCI 2.2 standards. It supports a maximum of 512 program blocks and a block size of 128 KB at maximum. This module supports programming in formats including the ladder diagram, structured text, and function block diagram formats. Additionally, it has system firmware that allows for upgrading to enable advanced features.
