Emerson - GE Fanuc IC697CGR935

The GE Fanuc Emerson IC697CGR935 is a CPU that can be employed for the Series 90-70 of Programmable Logic Controllers (PLCs). The IC697CGR935 offers a speed of 96 Megahertz and high calculation efficiency employing an 80486DX4 microprocessor and a 32-bit floating-point for CPU redundancy applications. The IC697CGR935 is a single slot CPU that can be programmed and configured through either MS-DOS or Windows. It includes seven (7) LED indicators on the faceplate to show the CPU status. The IC697CGR935 includes a battery-backed fast CMOS RAM of one (1) megabyte with a key switch to protect the memory. The IC697CGR935 offers 12-kilo discrete inputs and outputs and 8-kilo analog inputs and outputs. The IC697CGR935 provides 0.4 microseconds per boolean function. It supports IC660, IC661, and IC697 I/O modules. This CPU has configurable data and program memory which can be locked and protected using either software or key password. The IC697CGR935 has three (3) serial ports.

The IC697CGR935 can be controlled using either programming software or the RUN/STOP three-position switch. The IC697CGR935 includes the top port 1 which is a 6-pin, female RJ-11 connector that is RS-232 compatible, the center port 2 which is a 15-pin female type D serial connector that is RS-485 compatible, and the bottom port 3 which is a 15-pin female type D serial connector that is non-isolated RS-485 compatible. The IC697CGR935 contains a lithium battery with a shelf life of 5 years at 20 degrees Celsius (68 degrees Fahrenheit) to maintain data, program memory, and calendar clock operation. The IC697CGR935 requires a current of 3.1 Amperes at a voltage of 5 Volts DC. The IC697CGR935 includes flash memory to store and save CPU firmware and user data during the upgrading process between PC and the serial port. The IC697CGR935 weighs approximately 1 kilogram (2.2 pounds) while shipping and operates at zero (0) to 60 degrees Celsius (32 to 140 degrees Fahrenheit) for industrial applications.

The IC697CGR935 CPU by GE Fanuc is a programmable processor based on the 80486DX4 instruction set. It is fully compatible with GE's PLC Series 90-30 and 90-70. It is used extensively in industrial applications to aid in the processing of floating-point computations. The CPU may be readily programmed by connecting it to a personal computer running MS-DOS or Windows. It operates on a 5 Volt supply of power. It is currently rated at 3.1 Amps. The CPU processes data using 1 MB of CMOS RAM and a battery powers the memory. The IC697CGR935 programmable CPU features two ports labeled Ports 1 and 2. To either of the ports, an AS693232SNP cable can be attached.
 The IC697CGR935 CPU's front panel features LED status indicators that light solid green in response to various events. When a cable is attached to any of the ports, the LEDs illuminate. The center-left LED displays the processor's operation, while the bottom LED represents I/O activity. Along with these LEDs, a three-position switch corresponding to the LEDs is supplied. The switch's top position enables all operations. Once the switch is in the middle position, all outputs are disabled, and when the switch is in the bottom position, the CPU exits the RUN mode. The IC697CGR935 CPU must be operated in a temperature range of 0 to 50 degrees Celsius. For temperatures more than 50 degrees Celsius, forced cooling techniques must be used. An RJ 45 connector is provided on the IC697CGR935 CPU for network and communication connectivity.
