AS-BDAU-208模块备件

冗余CPU配置
在具有冗余CPU的配置中，IP地址必须设置如下：
1.关闭备用CPU（断电）。
2.将IPConfig工具连接到主CPU，并设置
主CPU上的CN1端口。请参阅IPConfig联机帮助。
（2） CEX总线上的大总限制是电气限制，可能会有进一步的限制
用于特定单元的性能。
（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，支持在线升级
固件。
建议始终使用以下命令启动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。
一次上电时，主处理器始终是连接到
RCU链路连接器标记为“上部”。

3.在备份CPU上设置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
控制器。
I/O系统
有几种将I/O系统连接到AC 800M控制器的方法：
•通过CI856进行S100 I/O。
•通过模块总线的S800 I/O单元。支持运行期间的热配置，
各级冗余、HART路由和事件序列（SOE）。
•通过CI854/CI854A和CI840/CI840A、PROFIBUS DP的S800 I/O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中设置备份CPU的IP地址。
备份CPU、CN1和CN2端口的IP地址将仅用于
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将永远不会注意到
转换。

模块总线
除PM891外，AC 800M控制器中的模块总线由一个
电气和一个光学单元。PM891仅由光学模块总线组成。
以下是ModuleBus的详细信息：
•电气模块总线（参见160页图54）–1个集群（组），带有
多连接12个S800 I/O单元。
•光模块总线（参见160页图54）–7个集群（组），带有
连接的大7 x 12=84个S800输入/输出单元。
请注意，电气模块总线只能用于连接S800 I/O
当AC 800M以单CPU配置运行时。
PM851/PM851A仅限于一个光模块总线集群。
使用冗余将减少S800信道的大数量。每个
集群多可包含12个单个S800 I/O单元或6个冗余S800 I/O
单位Redundant CPU Configurations
In configurations with redundant CPU, the IP address must be set as follows:
1. Switch off the backup CPU (power down).
2. Connect the IPConfig tool to the primary CPU and set the IP address of the
CN1 port on the primary CPU. See IPConfig online help.
(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.

• S800 I/O units via CI854/CI854A and CI801, PROFIBUS DP. Support for
HART routing, and hot configuration during run.
• S900 I/O units can be connected to PROFIBUS DP.
• ABB Drives can be connected to the ModuleBus, via CI801 and also via
Modulebus on the PM8xx. Some Drives equipment can be connected directly
to PROFIBUS or PROFINET IO. Please refer to Drives-specific
documentation for more information.
• Genius remote I/O (TRIO) via the CI862 Interface
• Satt I/O on ControlNet (19” Satt rack I/O, S200 I/O and S200L I/O) via the
CI865
• PROFINET IO via CI871
For more information on supported I/O systems and units, see I/O documentation.
ModuleBus
The ModuleBus in the AC 800M controller, except PM891, consists of one
electrical and one optical unit. The PM891 consists of optical ModuleBus only.
The following are the details of the ModuleBus:
• Electrical ModuleBus, (see Figure 54 on page 160) – 1 cluster (group), with a
maximum of 12 S800 I/O units connected.
• Optical ModuleBus (see Figure 54 on page 160) – 7 clusters (groups), with
maximum 7 x 12 = 84 S800 I/O units connected.
Note that the electrical ModuleBus can only be used for connection of S800 I/O
when AC 800M is running in single CPU configuration.
PM851/PM851A is restricted to one optical ModuleBus cluster.
Use of redundancy will reduce the maximum number of S800 channels. Each
cluster may contain up to 12 single S800 I/O units or up to 6 redundant S800 I/O
units
