The IC695CPU315 1 GHz Central Processing Unit

The IC695CPU315 is a 1 GHz Central Processing Unit from the GE Fanuc PACSystems RX3i Series. It has an Intel Celeron-M  microprocessor with 20 MB of user memory (also known as random access memory or RAM) and 20 MB of flash storage memory. As a programmable controller, the  IC695CPU315 is capable of up to 32K I/O operations per second. It supports up to 512 program blocks at a maximum size of 128 KB per block. The IC695CPU315 communicates with I/O and Intelligent Option modules using a dual backplane bus.

RX3i CPUs like this one are designed for real-time control of machines, processes, and material handling systems. They can be programmed in C, or in three of the five programming languages recognized by the IEC (International Electrotechnical Commission). From the IEC language list specifically, you can program IC695CPU315 in Ladder Logic (Ladder Diagram), Structured Text, or Function Block Diagram languages. Only the Sequential Function Chart and Instruction List language options do not apply.

IC695CPU315 uses floating point algorithms, and its firmware can be upgraded within the system. Auto-located Symbolic Variables can use as much memory as they need, up to the full 20 MB capacity of user memory. The CPU comes factory-configured with two front=facing ports, an RS-485 serial port and an RS-232 serial port. Accordingly, you have both a 9-pin connector and a 15-pin connector. The CPU supports the SNP, Serial I/O, and Modbus Slave and Master serial protocols. IC695CPU315 also supports most of the older GE Fanuc Series 90-30 modules and expansion racks.
