PM891 处理器是一个单片单元，配备电源、CPU 板和单元终端。该装置包含微处理器和 RAM 存储器、实时时钟、LED 指示灯、INIT 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-Bus）安装在设备上。CEX-Bus用于通过通信接口单元扩展车载通信端口。可以在 CEX-Bus 上使用冗余通信接口。CEX-Bus 互连单元 BC810 用于通过将 CEX-Bus 划分为单独的段来提高 CEX-Bus 的可用性。该单元的光模块总线可用于连接七个 S800 I/O 单元集群（每个集群最多包含 12 个单元）。每个 PM891 都有一个唯一的以太网地址，用于为设备提供硬件标识。

The PM891 processor is a single chip unit with a power supply, CPU board, and unit terminal. The device includes 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 the on-board communication port through the communication interface unit. Redundant communication interfaces can be used on the CEX-Bus. The CEX-Bus interconnect unit BC810 is used to improve the availability of the CEX-Bus by dividing the CEX-Bus into separate segments. The unit's optical module bus can be used to connect up to seven clusters of S800 I/O units (each containing up to 12 units). Each PM891 has a unique Ethernet address that provides a hardware identity for the device.
