PM891? COM4端口是隔離的，用于配置工具

ABB AC800M系列 PM891 處理器

PM891處理器是一個單片單元，配有電源、CPU板和單元終端。PM891該單元包含微處理器和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)部電池。PM891有兩個用于連接控制網(wǎng)絡的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冗余以獲得更高的可用性（CPU、CEX總線、通信接口和S800 I/O）。

通信擴展總線（CEX總線）安裝在裝置上。CEX總線用于擴展帶有通信接口單元的車載通信端口?？梢栽贑EX總線上使用冗余通信接口。CEX總線互連單元BC810用于通過將其劃分為單獨的段來增加CEX總線上的可用性。該單元的光學模塊可用于連接S800 I/O單元的七個集群（每個集群最多包括12個單元）。每個PM891都有一個唯一的以太網(wǎng)地址，為單元提供硬件標識。

ABB AC800M series PM891 processor

The PM891 processor is a single chip unit with a power supply, CPU board, and unit terminal. The PM891 unit contains a microprocessor and RAM memory, real-time clock, LED indicator, INIT button, and secure digital interface. The PM891 does not contain any internal batteries. The 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. The 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 device. The CEX bus is used to extend vehicle communication ports with communication interface units. Redundant communication interfaces can be used on the CEX bus. The CEX bus interconnect unit BC810 is used to increase availability on the CEX bus by dividing it into separate segments. The unit’s optical module can be used to connect seven clusters of the S800 I/O unit (each cluster consists of up to 12 units). Each PM891 has a unique Ethernet address that provides a hardware identity for the unit.
