Product Description of IC697CPX928
The IC697CPX928 is a Programmable Logic Controller manufactured by GE Automation and Controls. It is designed to fit into a single rack slot and comes with three built-in serial ports. A backplane mounted on the rack allows this device to communicate with several different modules. A run/stop control switch with three positions or specific software running from an attached computer is used to control the IC697CPX928. Seven on-board LED lights display operational status.
Features of this device include a 96MHz 80486DX4 microprocessor, floating point calculations, processor speeds of 0.4 microseconds for each Boolean function, 8K analog I/O, and 12K I/O of any mix. The IC697CPX928 supports several modules, including IC697 LAN interface modules and various display, coprocessor, communications, and link interface modules. IC660/61 bus controllers and IC697 discrete and analog I/O modules are also compatible with this device.
To program this device, connect it to a computer loaded with MS-DOS, Windows 95, or Windows NT. This connection is possible by way of a serial, parallel, or Ethernet interface. For Ethernet connections to the programming computer, special hardware is required. As the IC697CPX928 is programmed via software, hardware setup with DIP switches and jumpers is not required. Device configuration settings can be protected digitally via a password and physically by a keyswitch.
The IC697CPX928 provides six megabytes of user and program data memory. This memory is maintained by a lithium CMOS battery. Up to 256 kilobytes of optional flash memory (NVRAM) is also supported. Operating system firmware is stored in flash memory. Device disassembly or EPROM replacement is not required to update firmware.
In environments where temperatures reach 122 degrees Fahrenheit (50 Celsius), a fan capable of 70 cubic feet per minute (CFM) is required to prevent overheating.
The product manual contains detailed guidelines for installing the IC697CPX928. Rack power should be off before installing. The operation control switch should be in the stop position. The memory protection keyswitch should be in the off position. Place the CMOS battery into one of the battery connection slots. Insert the device into the rack and resume power.

The nominal current required by the IC697CPX928 module is 3.1 Amps. The input voltage required is 5 Volts DC. With forced air-cooling rated at 70 CFM, the module can be operated at ambient temperatures between 32 and 140 degrees Fahrenheit. Without forced air-cooling, the range of operating temperatures of the IC697CPX928 CPU module is reduced to between 32 and 122 degrees Fahrenheit. Depending on the types of power supply that are available, 120 Volts AC, 240 Volts AC, or 24 Volts DC-powered rack fan assemblies can be installed on the IC697CPX928 module. The CPU module comes with 3 serial ports, of which 2 ports support RS-485 communication and 1 port supports RS-232 communication. These serial ports can be used to interface with programming devices for CPU configuration. Additionally, optional Ethernet modules can also be installed in the PLC to enable the configuration of the IC697CPX928 module over Ethernet networks. The I/O supported by the IC697CPX928 module include a maximum of 8000 analog I/O and 12,000 I/O in any mix. The IC697CPX928 module requires 1 slot in GE Fanuc Series 90-70 PLC rack for installation. A total of 7 LEDs are provided on the front of module for status updates.
