PM891 處理器是一個單片單元，配備電源、CPU 板和單元終端。該裝置包含微處理器和RAM存儲器、實時時鐘、LED指示燈、INIT按鈕和安全數(shù)字接口。PM891 不包含任何內(nèi)置電池 PM891 有兩個用于連接到控制網(wǎng)絡(luò)的 RJ45 以太網(wǎng)端口（CN1、CN2）和一個 RJ45 串行端口 （COM4）。COM4 端口是隔離的，用于配置工具。PM891 支持 CPU 冗余以實現(xiàn)更高的可用性（CPU、CEX 總線、通信接口和 S800 I/O）。
通信擴展總線（CEX-Bus）安裝在本機上。CEX-Bus 用于擴展帶有通信接口單元的板載通信端口?？梢栽?CEX-Bus 上使用冗余通信接口。CEX-Bus 互連單元 BC810 用于通過將 CEX-Bus 劃分為單獨的段來提高其可用性。該單元的光學(xué)模塊總線可用于連接七個 S800 I/O 單元集群（每個集群最多包含 12 個單元）。每個 PM891 都提供唯一的以太網(wǎng)地址，為設(shè)備提供硬件標識。

The PM891 processor is a single-chip unit equipped with a power supply, CPU board, and unit terminal. The device includes a microprocessor and RAM memory, real-time clock, LED indicator light, INIT button, and secure digital interface. PM891 does not contain any built-in batteries. PM891 has two RJ45 Ethernet ports (CN1, CN2) and one RJ45 serial port (COM4) for connecting to the control network. The COM4 port is isolated and used for configuration tools. PM891 supports CPU redundancy for higher availability (CPU, CEX bus, communication interface, and S800 I/O).
The communication extension bus (CEX-Bus) is installed on the local machine. CEX-Bus is used to expand onboard communication ports with communication interface units. Redundant communication interfaces can be used on CEX-Bus. The CEX-Bus interconnect unit BC810 is used to improve its availability by dividing the CEX-Bus into separate segments. The optical module bus of this unit can be used to connect seven S800 I/O unit clusters (each cluster can contain up to 12 units). Each PM891 provides a unique Ethernet address to provide hardware identification for the device.
