5 Controller redundancy

控制器冗余

 

5.1 Overview

概述

 

The availability of the AC 900F and AC 800F process stations can be increased by operation in redundant mode, i.e. the entire process station is configured twice.

AC 900F和AC 800F过程站的可用性可以通过在冗余模式操作提高可用性。即整个过程站配置两次。

 

In case of redundancy, a bumpless toggle is achieved between the active controller (Primary) and the passive controller (Secondary), so that:

在冗余情况下，活动控制器（主）和被动控制器（备）之间实现无扰切换，这样的话：

• in case of failure of the CPU module, PROFIBUS or CAN communication interface or 24 VDC power supply, the outputs of I/O components at connected
  fieldbusses are maintained,
• 在CPU模块、PROFIBUS或CAN通信接口或24 VDC电源故障的情况下，连接现场总线的I/O组件的输出保持不变。
• the internal statuses (component data, variable values) are maintained,
• 内部状态(组件数据、变量值)得到维护。
• configuration and working data are automatically adjusted between the active and passive controller。
• 配置和工作数据在主和备控制器之间自动调整。

The list box for a redundant process station features only the modules that can be used in redundant configuration. These modules are marked with an R for the AC 800F, e.g. FI 830FR. The parameter definition dialogs of redundant modules slightly differ from those for modules that cannot be used in redundant configuration. As the hardware of modules that are capable of redundancy is identical with the hardware of modules that are not capable of redundancy, these modules are interchangeable.

冗余过程站的列表框只包含可在冗余配置中使用的列表框。对AC 800F（控制器来说），这些模块（的型号）使用R标记，比如FI 830FR。冗余模板的参数定义对话框与不能在冗余配置使用的模板的对话框稍微不同。具有冗余能力的模块与不具备冗余能力的模块硬件上时相同的，这些模块是可以互换的。

 

The redundancy link between both controllers that is used for redundancy adjustment is automatically generated and need not be configured. For detailed information on the IP address setting for the exchange of redundancy data, see the corresponding Mounting and Installation Instructions.

两个控制器之间的冗余链路用于冗余调整，是自动生成的，且不需要配置的。关于冗余数据交换的IP地址设置细节信息，参见相应的安装指导。

 

To distinguish between both controllers, they are marked with IP1 and IP2. A redundant process station is always configured with two IP addresses, with the IP address 1 being used to address the upper IP1 controller and the IP address 2 for the lower IP2 controller.

为了区分两个控制器，它们被标注IP1和IP2。一个冗余过程站经常配置两个IP地址，其中IP地址1用于上面的IP1控制器，IP地址2用于下面的IP2控制器。

 

In a redundant network, the IP addresses 1 and 2 must be configured for the network lines A and B.

在冗余网络，IP地址1和IP地址2必须配置为网络线路A和网络线路B

 

The assignment of the IP address 1 or 2 does not define which controller acts as Primary or Secondary. With online connection, either the Primary or the Secondary may be in the upper position. See Network configuration in the hardware structure on page 38.

IP地址1和2的分配没有定义那个控制器作为主或者备。在线连接时，主或者备控制器都可能是上面那个。参阅第38页硬件结构中的网络配置。
