Description
The IC697CPU788 is a 32-bit Programmable Logic Controller intended for use in critical IC660/661 environments where an emergency shutdown may be necessary. When used with C program blocks, the IC697CPU788 is capable of supporting Triple Modular Redundancy (TMR). There are two methods to operate this device: The run/stop switch or a connected computer loaded with the correct software. “Smart option” and I/O modules such as IC697 LAN and I/O link interface modules, alphanumeric display modules, bus controllers for IC660 and IC661 devices, and IC697 discrete and analog modules are all supported. Note: IC697 I/O modules must be in simplex mode. To facilitate communication with these modules, the IC697CPU788 uses a backplane mounted to the rack.
Other features of this device include a 16MHz microprocessor, processor speeds of 0.4 microseconds for each Boolean function, 8K analog I/O (simplex mode), 352 discrete I/O (simplex mode), 112 voted discrete inputs, 80 voted discrete outputs, and 1024 voted analog inputs. Data storage for the IC697CPU788 is provided by an attached memory expansion board. A CMOS battery supports 512 kilobytes of memory, 200 kilobytes of which is allotted for program data.
Configuration for this device is done via software from a computer. Jumpers and DIP switches are not needed. A computer running MS-DOS is used to program the IC697CPU788. Programming and setup is also possible with Windows 95/NT. A serial or parallel connection is used for programming, and if special hardware is installed, an Ethernet interface is also a possibility. For security reasons, configuration data is protected by passwords and a physical protection switch built into the device.
Follow the directions found in the manual during installation. Before installing, remove the power source from the rack. Turn off the configuration protect switch and move the operation control switch to the stop position. Insert the lithium battery. Attach the memory board using a Phillips screwdriver. Connect the IC697CPU788 to the rack, and restore power.
