The IC697CPM790 is a 90-70 series Programmable Logic controller (PLC) CPU. The CPU is a single slot wide module designed for critical applications such as emergency shutdown systems, fire fighting, gas and other applications. The CPU supports triple media redundancy (TMR), enabling automated test routines by merging separate C programs.

The IC697CPM790 has 1mb of battery-supported memory and can use up to 512KB of memory through user programs configured using the ladder diagram programming language. When configured in simplex mode, the CPU supports any combination of discrete input and output points up to 12K; 2048 discrete inputs and 2048 discrete outputs. Similarly, the IC697CPM790 is capable of handling up to 8K analog inputs and outputs, any combination when operating in simplex mode and 1024 voting analog inputs. It is equipped with an 80486DX2 microprocessor with a clock speed of 64 MHz. The CPU has a relatively fast scan speed of 0.4 microseconds per Boolean function, making it suitable for use in critical applications.

The IC697CPM790 supports Triple module redundancy (TMR), which is used to allow the system to have no chance of downtime. This TMR setup basically consists of three PLC racks, each with a (1)IC697CPM790 CPU, three genius I/O buses, as well as three input sensors and three output loads.

The IC697CPM790 comes with a (1) 15-pin sub-D connector that allows communication with RS485 compatible devices. Using RS-422/RS-485 to RS-232 converters (part number IC690ACC900) or RS-232 to RS-422 mini-converters (part number IC690ACC901), other forms of communication can be established, such as connecting to a programming computer.

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 Windows or MS-DOS software and is capable of communicating with I/O modules and smart option modules installed in the same PLC system via a rack-mounted backplane. The IC697CPM790 Programmable controller CPU cannot run unless a separate C program is included as part of the application loaded by the CPU.

The IC697CPM790 programmable controller CPU must be used with a separate C program for operating TMR or triple module redundancy and automated test and operation routines. This CPU has 1mb of battery-supported memory, with up to 512 KB of memory available for ladder diagram programs. The IC697CPM790 programmable controller CPU can process up to 12,000 discrete inputs and outputs in any mix, and it can process up to 2048 discrete inputs and up to 2048 discrete outputs as long as both inputs and outputs are in simplex mode. Additional features of the CPU include configurable program and data storage, 4 status indicator leds, password-controlled machine access, a 3-bit operating mode control switch, and a battery-supported calendar clock.
