PM891处理器是一个配有电源、CPU板和单元终端的单片单元。该装置包含微处理器和RAM内存、实时时钟、LED指示灯、初始化按钮和安全数字接口。PM891不包含任何内部电池。PM891有两个用于连接控制网络的RJ45以太网端口（CN1、CN2）和一个RJ45串行端口（COM4）。COM4端口是隔离的，用于配置工具。PM891支持CPU冗余以实现更高的可用性（CPU、CEX总线、通信接口和S800 I/O）。通信扩展总线（CEX总线）安装在装置上。CEX总线用于通过通信接口单元扩展车载通信端口。可以在CEX总线上使用冗余通信接口。CEX总线互连单元BC810用于通过将CEX总线划分为单独的段来提高其可用性。该单元的光学模块总线可用于连接七组S800输入/输出单元（每个单元最多包含12个单元）。每个PM891都有一个唯一的以太网地址，该地址为装置提供硬件标识。

Programmable automatic controller, suitable for high reliability control application in process industryThe rich function application library contains a variety of control circuit types, such as advanced control and self-tuning functions, and integrates ABB drive and motor applications. The controller communication includes the built-in rnrp redundant communication based on Ethernet and the connection of various communication modules to third-party equipment. The advanced redundancy concept can ensure fast switching between controllers and flexible topology. A variety of CPU types are available, and the processing performance, memory size and redundancy functions can be flexibly selected. Priority based and cycle based tasks can ensure the highest stability even in the case of complex control tasks.The programming tool is compact control builder, which supports the programming language of Standard IEC 61131-3, and can configure the control program and the hardware configuration of AC 800m. Through one database, all functions such as logic, sequence control and analog quantity control can be realized for all controllers in an automation system. Flash cards enable applications to be loaded without engineering tools for OEM and remote solutions.AC 800m is a product family, based on rail installation, including a variety of CPUs, communication modules, power supply modules and a wealth of accessories. There are 7 kinds of controllers available, ranging from the controller with medium processing performance to the controller with high performance and full redundancy. Users can determine them according to application requirements and prices.
