ABB AC800M 3BSE053242R1 PM891K02冗余處理器單元450MHZ和256MB。兩個模塊冗余使用保護系統(tǒng)質(zhì)量管理操作

450MHZ和256MB。
包裝包括:
– 2個PM891K01處理器單元
– TK850V007 CEX總線延長電纜
– TK855 RCU數(shù)據(jù)鏈路電纜
– TK856 RCU控制鏈接電纜
-不含許可證
(BC810K02不包括在PM891K02冗余處理器單元套件中。為了實現(xiàn)PM891處理器單元的熱更換，需要單獨訂購BC810K02。)

AC 800M是一系列軌裝模塊，由CPU、通信模塊、電源模塊和各種附件組成。有幾個CPU模塊可供選擇，從中等處理器能力和低成本到高處理器能力和支持完全冗余。

PM891

PM891處理器是一個單片單元，配有電源、CPU板和單元終端。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(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(xué)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(biāo)識。

PM891

ABB AC800M 3BSE053242R1 PM891K02 Redundant processor unit 450MHZ and 256MB. Two modules are redundant using protection system quality management operations

450MHZ and 256MB.
The package includes:
– 2 PM891K01 processor units
– TK850V007 CEX bus extension cable
– TK855 RCU data link cable
– TK856 RCU control link cable
– License not included
The BC810K02 is not included in the PM891K02 redundancy processor unit suite. For hot replacement of the PM891 processor unit, the BC810K02 needs to be ordered separately.)

The AC 800M is a series of rail-mounted modules consisting of a CPU, communication module, power module and various accessories. There are several CPU modules to choose from, ranging from medium processor power and low cost to high processor power and support for full redundancy.
The PM891 processor is a single chip unit with a power supply, CPU board, and unit terminal. The 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.
