IC697CPM790-GD 三重 Genius I/O 总线，以及三重输入传感器和三重输出负载

该IC697CPM790-GD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-GD 配有一  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 IC422ACC485 的 RS-232/RS-690 至 RS-900 转换器或部件号为 IC232ACC422 的 RS-690 至 RS-901 微型转换器来建立。

IC697CPM790-GD可编程控制器 CPU 还适用于关键的工业和商业安全相关应用，例如火灾和气体相关应用以及 ESD 或紧急关机系统。它使用 Windows 或 MS-DOS 软件进行编程，并能够通过机架安装背板与安装它的同一 PLC 系统中的 I/O 模块和智能选件模块进行通信。IC697CPM790-GD可编程控制器 CPU 无法运行，除非独立 C 程序作为 CPU 加载的应用程序的一部分包含在内。

IC697CPM790-GD可编程控制器 CPU 必须与独立 C 程序一起使用，以运行 TMR 或三重模块化冗余以及自动测试和操作例程。该 CPU 具有 1 MB 的电池备份内存，高达 512 KB 的内存可用于梯形图程序。IC697CPM790-GD可编程控制器 CPU 可以处理多达 12,000 个离散输入和输出，只要输入和输出都处于单工模式，它就可以处理多达 2048 个离散输入和多达 2048 个离散输出。该 CPU 的其他功能包括可配置的程序和数据存储器、4 个状态指示灯 LED、密码控制的机器访问、一个 3 位操作模式控制开关和一个电池供电的日历时钟。

The IC697CPM790-GD 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-GD 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-232/RS-690 to RS-900 converters with part number IC422ACC485 or RS-690 to RS-901 microconverters with part number IC232ACC422.

The IC697CPM790-GD 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 in the same PLC system on which it is installed via a rack-mounted backplane. The IC697CPM790-GD programmable controller CPU cannot run unless a stand-alone C program is included as part of the application loaded by the CPU.

The IC697CPM790-GD programmable controller CPU must be used with stand-alone C programs to run TMR or triple modular redundancy as well as automated test and operation routines. The CPU has 1 MB of battery backup memory, and up to 512 KB of memory can be used for ladder diagram programs. The IC697CPM790-GD programmable controller CPU can handle up to 12,000 discrete inputs and outputs, and it can handle 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-operated calendar clock.
