IC697CPM790-GD Programmable Logic Controller

The IC697CPM790 is a Series 90-70 Programmable Logic Controller (PLC) CPU. This CPU is

a single slot wide module that is specifically used for critical applications such as Emergency shutdown

systems, fire, gas and other applications. This CPU supports Triple Media Redundancy (TMR) by incorporating Standalone C program for enabling autotest routines as well.

The IC697CPM790 features 1 MB of battery-backed memory with up to 512KB available for utilization

by the user program configured using ladder diagram programming language. This CPU supports up to 12K

discrete input and output points, of any combination, when configured in simplex mode; 2048 voted discrete

inputs and 2048 voted discrete outputs. Similarly, the IC697CPM790 is capable of handling up to 8K analog inputs

and outputs, of any combination when operated in simplex mode and 1024 voted analog inputs. It is equipped

with an 80486DX2 microprocessor with clock speed of 64 MHz. This CPU exhibits a relatively fast scan rate of 0.4 microseconds per boolean function, suitable for use in critical applications.

The IC697CPM790 supports Triple Modular Redundancy (TMR), utilized to allow the system without the chance

of downtime. This TMR set-up is basically comprised of Triple PLC Racks with each rack having One (1) IC697CPM790

CPU, Triple Genius I/O Busses, as well as Triple input sensors and Triple output loads.

IC697CPM790

The IC697CPM790 comes with One (1) 15-pin sub-D connector allowing communication with RS485 compatible

devices. Other forms of communication such as connection to a programming computer may be established with the

use of RS-422/RS-485 to RS-232 Converter with part number IC690ACC900 or RS-232 to RS-422 Miniconverter with part number IC690ACC901.

The IC697CPM790 programmable controller CPU is also suitable for critical industrial and commercial safety-related

applications such as fire and gas-related applications and ESD or Emergency Shutdown systems. It is programmed using

the Windows or MS-DOS software and able to communicate with the I/O modules and the smart option modules in the same

PLC system that it is installed in through the rack-mounted backplane. The IC697CPM790 programmable controller CPU cannot

operate unless a Standalone C program is included as part of the loaded application program for the CPU.
