PM891 处理器是配备电源、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 不包含任何内置电池 PM891 有两个 RJ45 以太网端口（CN1、CN2）用于连接到控制网络，以及一个 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-Bus、通信接口和 S800 I/O）。

通信扩展总线（CEX-Bus）安装在本机上。CEX-Bus用于扩展带有通信接口单元的板载通信端口。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。该单元的光纤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，为设备提供硬件标识。

包装包括：

2 件 PM891K01 处理器单元

1 件 TK850V007 CEX总线延长线

1 件 TK855 RCU 数据链路电缆

1 件 TK856 RCU 控制链路电缆

请注意：BC810K02不包含在 PM891K02冗余处理器单元套件中。为了热更换 PM891 处理器单元，需要BC810K02，并且必须单独订购。

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 built-in batteries The PM891 has two RJ45 Ethernet ports (CN1, CN2) for connecting to the control network, and a RJ45 serial port (COM4). 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 this machine. The CEX-Bus is used to extend the onboard communication port with a 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 fiber module bus can be used to connect up to seven clusters of S800 I/O units (each cluster contains up to 12 units). Each PM891 has a unique Ethernet address that provides a hardware identity for the device.

The package includes:

2 PM891K01 processor units

1 TK850V007 CEX bus extension cable

1 piece TK855 RCU data link cable

1 piece TK856 RCU control link cable

Please note that the BC810K02 is not included in the PM891K02 redundancy processor unit suite. For hot replacement of the PM891 processor unit, the BC810K02 is required and must be ordered separately.
