GE IC697CPM790-GD 中央处理器

IC697CPM790是一款90-70系列可编程逻辑控制器（PLC）CPU。该CPU是一个单插槽宽的模块，专门用于紧急停机系统、消防、燃气和其他应用等关键应用。该 CPU 通过结合独立 C 程序支持三重媒体冗余 （TMR） 以启用自动测试例程。

IC697CPM790具有1 MB电池备份存储器，高达512KB可供使用梯形图编程语言配置的用户程序使用。当配置为单工模式时，此 CPU 支持多达 12K 的任意组合离散输入和输出点;2048 个投票的离散输入和 2048 个投票的离散输出。同样，IC697CPM790能够在单工模式和8个投票模拟输入下工作时处理高达1024K的模拟输入和输出，包括任意组合。它配备了时钟速度为 80486 MHz 的 2DX64 微处理器。该CPU具有相对快速的扫描速率，每个布尔函数0.4微秒，适用于关键应用。

IC697CPM790支持三重模块化冗余（TMR），用于使系统没有停机的机会。这种TMR设置基本上由三重PLC机架组成，每个机架具有一（1）个IC697CPM790 CPU，三重Genius I / O总线，以及三重输入传感器和三重输出负载。

IC697CPM790 配有一 （1） 个 15 针子 D 连接器，可与 RS485 兼容设备通信。其他形式的通信，例如与编程计算机的连接，可以使用部件号为IC422ACC485的RS-232/RS-690至RS-900转换器或部件号为IC232ACC422的RS-690至RS-901微型转换器建立。

IC697CPM790 is a 90-70 series Programmable logic controller (PLC) CPU. This CPU is a single slot wide module specifically designed for critical applications such as emergency shutdown systems, firefighting, gas, and other applications. This CPU supports Triple Media Redundancy (TMR) in combination with independent C programs to enable automatic testing routines.

IC697CPM790 has 1 MB of battery backup memory and up to 512KB for user programs configured using ladder programming language. When configured in simplex mode, this CPU supports up to 12K of any combination of discrete input and output points; Discrete inputs for 2048 votes and discrete outputs for 2048 votes. Similarly, IC697CPM790 can handle up to 1024K analog inputs and outputs, including any combination, when operating in simplex mode and 8 voting analog inputs. It is equipped with a 2DX64 microprocessor with a clock speed of 80486 MHz. The CPU has a relatively fast scanning rate of 0.4 microseconds per Boolean function, which is suitable for key applications.

IC697CPM790 supports Triple Modular Redundancy (TMR) to prevent system downtime. This TMR setup basically consists of three PLC racks, each with one (1) IC697CPM790 CPU, three Genius I/O buses, as well as three input sensors and three output loads.

IC697CPM790 is equipped with one (1) 15-pin sub D connector that can communicate with RS485 compatible devices. Other forms of communication, such as connections to programming computers, can be established using RS-232/RS-690 to RS-900 converters with part number IC422ACC485 or RS-690 to RS-901 microconverters with part number IC232ACC422.
