具有处理器模块PM861、PM864、PM865、PM866和PM891。
启动时，有关CEX总线和CEX模块的一些事项必须：
启动冗余AC 800M系统时应考虑：
•不使用BC810装置：
–如果有基板，则必须至少插入一个CEX模块
在其他位置插入模块。
CEX-BUS提供车载通信端口的扩展。

标记为“上”）必须一次作为主CPU启动。
启动模式
热启动
启动应用程序控制任务。变量值初始化，除非
标记为保留或冷保留。
要启动热重启，请断开电源几秒钟。
电源故障后，热重启功能将自动启动
在电源恢复时。
冷重启
应用程序重新启动。变量值初始化，除非标记为“冷”
保持
要启动冷重启，必须通过短按重新启动控制器
初始化按钮（小于2.5秒）。
冗余配置中的冷重启
要重新启动以冗余配置运行的CPU：
1.执行备份CPU的控制器重置（见下文）。该系统将继续运行
进入单CPU状态。
2.等待几秒钟，然后按INIT push重新启动主CPU
按钮不到2.5秒。
3.系统将再次升级到同步CPU状态。
电源故障后，而不是热重启应用程序SIL3
使用cold retain ma重新启动应用程序

Start-up
Refer to relevant document for information on:
• Firmware download
• Controller IP address
• Downloading application
• Updating firmware
Start-up in Redundant Configuration (CEX Bus Considerations)
The redundant configuration using CEX bus and CEX modules is supported along
with the processor modules PM861, PM864, PM865, PM866 and PM891.
At start-up, some things regarding the CEX bus and CEX modules have to be
considered when starting up a redundant AC 800M system:
• Without using BC810 units:
– At least one CEX module must be inserted, if there are base plates without
inserted modules in other positions.
CEX-BUS Provides extension of on-board communication ports.
Valid for PM861/PM864/PM865
RCU Link Connector Provides information and data transfer between Primary
and Backup CPU in redundant configuration.
Valid for PM891
RCU Data Link
Connector
Provides transfer of data required to keep the backup
CPU synchronized with the primary CPU.
RCU Control Link
Connector
Provides role selection and CPU identity assignment.
(1) Electrical ModuleBus not valid for PM891.

Marking Function
Section 4 Operation Start Modes

– After having rebuilt the hardware on the CEX bus, that is, after removing
or adding a number of base plates (equipped with CEX modules or not)
the upper CPU (the CPU connected to the part of the RCU Link cable that
is marked “UPPER”) must be started as the primary CPU the first time.
Start Modes
Warm Start
Application-controlling tasks are initiated. Variable values are initialized unless
marked Retain or Cold retain.
To initiate a warm restart, disconnect the power supply for a few seconds.
Following a power failure, the warm restart function will be automatically initiated
on power restoration.
Cold Restart
The application program restarts. Variable values are initialized unless marked Cold
retain.
To initiate a cold restart, the Controller must be restarted by briefly pressing
the INIT push button (less than 2.5 seconds).
Cold Restart in Redundant Configuration
To restart CPUs running in redundant configuration:
1. Perform a Controller Reset of the backup CPU (see below). The system will go
into single CPU state.
2. Wait a few seconds and then restart the Primary CPU by pressing the INIT push
button less than 2.5 seconds.
3. The system will be upgraded to synchronized CPU state once again.
After a power fail, instead of doing a warm restart of the application SIL3
applications are restarted using cold retain ma
