The IC697CPU788 is a 32-bit programmable logic controller for critical IC660/661 environments that may require emergency shutdowns. When used with C program modules, the IC697CPU788 supports triple modular redundancy (TMR). There are two ways to operate this device: run/stop the switch or connect the computer with the correct software.
Support for "Smart options" and I/O modules such as the IC697 LAN and I/O link interface modules, alphanumeric display modules, bus controllers for IC660 and IC661 devices, and IC697 discrete and analog modules. Note: The IC697 I/O module must be in simplex mode. To facilitate communication with these modules, the IC697CPU788 uses a rack-mounted backplane.
When the switch is in a protected position, IC697CPU788 can only change the IC697CPU788 CPU configuration through a programmer connected to the parallel port. The current requirement for the module (including the expansion memory board) is 1.6 amps. The module is compatible with 5 V DC input voltage. Lithium batteries have a shelf life of 20 years at 10 degrees Celsius, and the battery offers a nominal memory retention of 6 months. Supports up to 352 discrete inputs and outputs in simplex mode and 8,000 analog inputs and 8,000 analog outputs in simplex mode. The IC697CPU788 module uses an 80386DX microprocessor. The microprocessor has a clock speed of 16 megahertz. The time required to process the Boolean function is 0.4 microseconds. Four status leds provide information about the system to installers and operators.
