（2） CEX总线上的大总限制是电气限制，由于以下原因，可能存在进一步的限制：
为特定单元执行。
（3） 在接口CI868、CI871和CI873中仅使用一个端口（CH1）。
如果冗余控制器（PM8XX）与冗余通信一起使用
接口，确保完全冗余并支持在线升级
固件。
建议采用以下方式启动IPConfig会话：
在分配预期IP地址之前，执行“恢复出厂设置”命令。
这将删除以前存储的备用MAC和IP地址（如果有）。看见
49页冗余配置中的MAC和IP地址处理。
在Control Builder中设置主CPU的IP地址时
备份CPU必须关闭（断电）。否则，备份CPU
会接管，你会断开连接。
一次加电时，主处理器始终是连接到
RCU链路接头标记为“上部”。

3.设置备份CPU上CN1端口的IP地址。使用默认设置
（0.0.2.0添加到主CPU的地址），除非您的网络
管理员另有要求。请参阅IPConfig联机帮助。
4.开始您的800xA工作场所。
5.在Project Explorer硬件树中创建控制器的表示。
确保PM861/PM864/PM865/PM891处理器单元定义为：
冗余的请参阅控件生成器联机帮助。
6.在Project Explorer中，将控制器的IP地址设置为
主CPU。请参阅控件生成器联机帮助。
7.打开辅助CPU。检查您是否与

输入/输出系统
有几种方法将I/O系统连接到AC 800M控制器：
•通过CI856的S100输入/输出。
•通过模块总线的S800输入/输出单元。支持运行期间的热配置，
各级冗余、HART路由和事件顺序（SOE）。
•通过CI854/CI854A和CI840/CI840A、PROFIBUS DP的S800输入/输出单元。
支持HART路由、各级冗余和热配置
在运行期间。
如果使用网络冗余，则主设备的CN2端口的IP地址
无法使用IPConfig设置处理器。必须在控制中设置此地址
建设者
如果使用网络冗余，您还必须设置CN2的IP地址
使用IPConfig的备份处理器的端口。请参阅IPConfig联机帮助。
无需在Control Builder中为备份CPU设置IP地址。
备份CPU、CN1和CN2端口的IP地址仅用于
主CPU和备用CPU之间的内部通信。当
备份CPU接管，它还接管定义的主IP地址
在控件生成器中。控制网络上的其他单元永远不会注意到
转换。

(2) The maximum total limit on CEX-Bus is the electrical one, there might be further limitations due
to performance for a particular unit.
(3) Only one port (CH1) is used in the interfaces CI868, CI871 and CI873.
If redundant controllers (PM8XX) are used along with redundant communication
interfaces, it ensures full redundancy and supports the online upgrade of
firmware.
It is recommended to make a practice of always starting an IPConfig session with
a “Restore factory settings” command before assigning the intended IP addresses.
This will erase previously stored alternative MAC and IP addresses if any. See
MAC and IP Address Handling in Redundant Configuration on page 49.
When setting the IP address of the primary CPU in Control Builder, the
backup CPU must be turned off (powered down). Otherwise the backup CPU
will take over and you get disconnected.
At the first power-up, the primary processor is always the one connected to the
RCU Link connector marked “UPPER”.

3. Set the IP address of the CN1 port on the backup CPU. Use default settings
(0.0.2.0 is added to the address of the primary CPU), unless your network
administrator requires otherwise. See IPConfig online help.
4. Start your 800xA Workplace.
5. Create a representation of the controller in the Project Explorer hardware tree.
Make sure the PM861/PM864/PM865/PM891 processor unit is defined as
redundant. See Control Builder online help.
6. In Project Explorer, set the IP address of the controller to the IP address of the
primary CPU. See Control Builder online help.
7. Switch on the secondary CPU. Check that you have communication with the
controller.
I/O Systems
There are several methods of connecting I/O systems to the AC 800M Controller:
• S100 I/O via CI856.
• S800 I/O units via the ModuleBus. Support for hot configuration during run,
redundancy on all levels, HART routing, and Sequence-of-Events (SOE).
• S800 I/O units via CI854/CI854A and CI840/CI840A, PROFIBUS DP.
Support for HART routing, redundancy on all levels, and hot configuration
during run.
If network redundancy is used, the IP address of the CN2 port of the primary
processor cannot be set using IPConfig. This address must be set in Control
Builder
If network redundancy is used, you also have to set the IP address of the CN2
port of the backup processor using IPConfig. See IPConfig online help.
There is no need to set IP address(es) for the backup CPU in Control Builder.
The IP address of the backup CPU, CN1 and CN2 ports will only be used for
internal communication between the primary and backup CPUs. When the
backup CPU takes over, it also takes over the primary IP address that is defined
in Control Builder. Other units on the control network will never notice the
switchover.
