>>>>>型号:IC697CPM790-GD 可编程逻辑控制器 支持三重模块化冗余
【功能描述】
IC697CPM790是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，专门用于关键应用，例如紧急停机系统、火灾、燃气和其他应用。该CPU通过整合独立的C程序来支持三重媒体冗余（TMR），以启用自动测试例程。
该IC697CPM790具有1 MB的电池备份内存，最高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的任意组合的离散输入和输出点;2048个投票的离散输入和2048个投票的离散输出。同样，该IC697CPM790能够处理高达8K的模拟输入和输出，在单工模式下运行时可处理任意组合的模拟输入和输出，并具有1024个投票模拟输入。它配备了时钟速度为80486 MHz的2DX64微处理器。该CPU具有相对较快的扫描速率，每个布尔函数0.4微秒，适用于关键应用。
该IC697CPM790支持三重模块化冗余（TMR），用于使系统不会停机。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sub-D连接器，可与RS485兼容设备通信。其他形式的通信，例如连接到编程计算机，可以使用部件号为IC690ACC900的RS-422/RS-485至RS-232转换器或部件号为IC690ACC901的RS-232至RS-422微型转换器来建立。

【英文介绍】
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, gas and other applications. The CPU supports triple media redundancy (TMR) by integrating separate C programs to enable automated test routines.
The IC697CPM790 has 1 MB of battery backup memory and up to 512KB is available for user programs configured using the ladder diagram programming language. When configured in simplex mode, this CPU supports any combination of discrete input and output points up to 12K; Discrete input of 2048 votes and discrete output of 2048 votes. Similarly, the IC697CPM790 is capable of handling analog inputs and outputs up to 8K, can handle any combination of analog inputs and outputs when run in simplex mode, and has 1024 voting analog inputs. It is equipped with a 2DX64 microprocessor with a clock speed of 80486 MHz. The CPU has a relatively fast scan rate of 0.4 microseconds per Boolean function, which is suitable for critical applications.
The IC697CPM790 supports Triple modular redundancy (TMR) for system downtime. This TMR setup essentially consists of triple PLC racks, each with one (1) IC697CPM790 CPU, triple Genius I/O bus, and triple input sensors and triple output loads.
The IC697CPM790 is equipped with one (1) 15-pin sub-D connector for communication with RS485 compatible devices. Other forms of communication, such as connection to a programmed computer, can be established using RS-422/RS-485 to RS-232 converters with part number IC690ACC900 or RS-232 to RS-422 microconverters with part number IC690ACC901.
