GE Fanuc IC695CPU310 CPU Module

The GE Fanuc IC695CPU310 is a CPU module ，it is a part of the GE Fanuc RX3i Series. It operates at 300 MHz and features an Intel Celeron (Pentium III) microprocessor with 10 MB of RAM and 10 MB of flash storage.

Communication and Protocols

This module has two embedded serial ports for RS-232 and RS-485 communications. These ports are conveniently located on the front of the chassis. They support three different serial protocols: Modbus RTU Slave, SNP, and Serial I/O. These protocols are essential for communicating with programmable logic controllers (PLCs) to facilitate data exchange. Notably, it utilizes the SNP Slave protocol for communication with Human-Machine Interface (HMI) devices.

System Status and LEDs

To provide quick system status information, the module features eight LEDs on the front panel. These LEDs follow standard conventions: blinking or red lights indicate faults, while steady green lights signify normal operation.

Backplane and Programming

The IC695CPU310 employs a dual backplane bus architecture. It is compatible with RX3i PCI and GE Fanuc Series 90-30-style serial bus usage. It supports up to 512 program blocks, each with a maximum size of 128 KB. This offers programming flexibility in languages such as Ladder Diagram, Structured Text, Function Block Diagram, and even C programming.
