Emerson - GE Fanuc IC697CPX772

The IC697CPX772 is a 96 Megahertz, 32-Bit Point, 512 Kilobyte (Slow) Memory Central Processing Unit (CPU). It is part of the 90-70 Series of modules by GE Fanuc. Features of the IC697CPX772 include the single slot CPU with three serial ports, 512 Kilobytes of battery-backed RAM memory in the same slot, and 256K of non-volatile user flash memory. Support for program Load/Store capabilities and Datagrams is included in Serial ports 1 and 2 (starting with Firmware Release 8.00). The IC697CPX772 supports BMA versions 7.92 and higher, as well as floating point calculations. Time per Boolean function is 0.4 microseconds, and the units comes standard with a 96 Megahertz, 80486DX4 microprocessor. The IC697CPX772 is programmed using MS-DOS software (or Windows software running Windows 95 or NT over Ethernet TCP/IP) through the included SNP port. The software used to configure the module (MS-DOS) does not support all features, like Bulk Memory Area (BMA); BMA requires configuration with Windows software 2.2 or later.

Additional features for this module include configurable program and data memory, a battery-backed calendar clock, access controlled by password, memory detection through keyswitch, and 7 status LEDs available to the operator. Specifications for the IC697CPX772 include a battery shelf life of 5 years at 20 degrees Celsius, or 68 degrees Fahrenheit. Battery memory retention is 6-month nominal without any applied power. The current required from 5 Volt bus is 3.1 Amperes (nominal). The IC697CPX772 has an operating temperature range between 0 and 60 degrees Celsius, or 32 to 140 degrees Fahrenheit. It has an elapsed time clock accuracy of .01% (maximum).

The GE Fanuc manufactured IC697CPX772 CPU module operates at 96 megahertz. The IC697CPX772 is a 32-bit point-to-point module with 512 KB of user memory. Additionally, 256 KB of non-volatile flash memory is included in the Module. The IC697CPX772 Module occupies one PLC rack slot. The Module is powered by an 80486DX4 CPU running at 96 megahertz. The Module includes three inbuilt serial ports. The three ports are self-contained and may be accessed through connections on the Module's front. Serial ports can be used to communicate with serial devices and terminals for serial programming. The RS-232 serial communication protocol is supported via Port 1, which is a 6-pin RJ-11 integration. The RS-485 serial communication standard is supported via Port 2, which is a 15-pin female D-connector.
 RS-485 is also supported on Port 3 of the IC697CPX772 CPU unit. Port 2 is optocoupler isolated, but Port 3 is not. The IC697CPX772 Module consumes 3.1 Amps of electricity. The Module requires a 5-volt direct current input voltage. 
 The Module operates between 32- and 140-degrees Fahrenheit. The IC697CPX772 module operates under the following conditions: a small enclosure with almost no airflow into the system. The IC697CPX772 Module supports the following three types of rack fan assemblies: 120 Volts AC-powered assemblies, 240 Volts AC-powered assemblies, and 24 Volts DC-powered assemblies. The IC697CPX772 Module features floating-point math, 2000 input/output channels, and 8000 analog I/O channels. The device is programmed using DOS or Windows-based software. Serial or Ethernet connections can be used to link the programming computer to the CPU module.
 The IC697CPX772's front panel features seven green LEDs that display the CPU's condition, including the toggle switch's position, serial port activity, memory protection, and the program's state. Its functioning is controlled by a three-position switch (RUN/STOP). Software passwords are used to secure user data. A key switch can be used to secure it manually. For safe and proper functioning, the end-user must properly install the PLC equipment.
