IC697CPM790 is a 90-70 series programmable logic controller CPU. The CPU is a single slot wide module specifically designed for critical applications such as emergency shutdown systems, fires, gas, and other applications. This CPU supports triple media redundancy by integrating independent C programs to enable automatic testing routines. The IC697CPM790 has 1 MB of battery backup memory and a maximum of 512KB for user programs configured using ladder programming language. When configured in simplex mode, the IC697CPM790 can handle up to 8K analog inputs and outputs, and can handle any combination of analog inputs and outputs when running in simplex mode, with 1024 voting analog inputs. It is equipped with a 2DX64 microprocessor with a clock speed of 80486 MHz. This CPU has a relatively fast scanning rate of 0.4 microseconds per Boolean function, making it suitable for critical applications.

The IC697CPM790 programmable controller CPU is also suitable for critical industrial and commercial safety related applications, such as fire and gas related applications, as well as ESD or emergency shutdown systems. It is programmed using Windows or MS-DOS software and can communicate with I/O modules and intelligent option modules in the same PLC system where it is installed through a rack mounted backplane. The IC697CPM790 programmable controller CPU cannot run unless a standalone C program is included as part of the application program loaded by the CPU. The IC697CPM790 programmable controller CPU must be used in conjunction with independent C programs to run TMR or triple modular redundancy as well as automatic testing and operation routines. This CPU has 1 MB of battery backup memory, and up to 512 KB of memory can be used for ladder programs.

PLC控制器本身的硬件采用积木式结构，各厂家产品结构大同小异。以日本欧姆龙C200HE为例，为总线模板框式结构，基本框架(CPU母板)上装有CPU模板，其它槽位装有I/O模板;如果I/O模板多时，可由CPU母板经I/O扩展电缆连接I/O扩展母板，在其上装I/O模板;另一种方法是配备远程I/O从站等。这些都说明了PLC厂家将硬件各部件均向用户开发，便于用户选用，配置成规模不等的PLC，而且这种硬件配置的开放性，为制造商、分销商(代理商)、系统集成商、最终用户带来很多方便，为营销供应链带来很大便利，这是一大成功经验。
