在以下情况下启用双超时：
•定义了冗余CI522。在CI522 DB元素中定义这两个模块可以启用
双倍超时。
•单个CI522从具有冗余通信接口的控制器接收数据。
当CI522 DB元件上的EN_DTMO终端为
设置为1。
•FCI从属于Advant Controller 450，自动使用与
Advant Controller 450。
如果一个电台没有双重超时，接收周期时间可以加倍
与发送周期时间相比，CDP不会超时。
3.2通信接口功能
通电（或重启）后，通信接口只有在设置后才能运行
由电站运行。
在其运行之前，通信接口不会在
Advant Fieldbus 100。此外，它不能分担总线主控责任
无法参与活动扫描表的配置算法。
定义为总线管理员参与总线主控的通信接口
责任。由于公共汽车管理员监督公共汽车上的交通
如果当前主控失败，好是
如果可能，将通信接口定义为总线管理员。

3.2.1节通信接口CI520

3.2.1通信接口CI520
3.2.1.1定义通信接口CI520
CI520通信接口用于Advant Controller 400系列。
总线通信接口的DB元素如图3-1所示。
3.2.1.2设置CI520操作
启动并配置CI520时，必须将其设置为可操作，以便启用
Advant Fieldbus 100上的通信，并参与总线主机的共享
责任。这由Advant控制器400系列自动完成。
如果CI520是一个投入运行的通信接口，它会立即假定
公共汽车主人的责任。
如果另一个通信接口在CI520之前成为总线主控接口，则CI520将检测
Advant Fieldbus 100上存在总线主控器，并努力实现同步。
如果CI520在其他通信接口已经存在的总线上被命令运行
分担总线主控责任，CI520向当前主控发送消息以通知
它的存在。然后，当执行以下操作时，当前总线主机将扫描表发送到CI520
公共汽车主人的责任。CI520将自己的CDP添加到扫描表中，然后请求
成为当前总线主控。收到总线主控权后，新更新的扫描表为
分发给所有其他总线管理员。
如果CI520因数据库更改而联机更改其配置。CI520
更新自己的扫描表，然后double time out is enabled when:
• redundant CI522s are defined. Defining both modules in the CI522 DB element enables
double time out.
• a single CI522 receives data from a controller with redundant communication interfaces.
The double time out is enabled when the EN_DTMO terminal on the CI522 DB element is
set to 1.
• FCIs subordinated an Advant Controller 450 use, automatically, the same CDP time out as
the superior Advant Controller 450.
If double time out is not available for a station the receiving cycle times can be doubled
compared to the sending cycle times and by this the CDP would not time out.
3.2 Communication Interface Functions
After power on (or restart), the communication interface can only become operational if it is set
operational by the station.
Until it is operational, the communication interface does not provide any transmissions on the
Advant Fieldbus 100 at all. Furthermore, it cannot share the bus master responsibilities, and it
can not participate in the configuration algorithms of the active scan table.
Communication interfaces defined as bus administrators participates in the bus master
responsibilities. As the bus administrators supervises the traffic on the bus and have the
possibility to take over the bus mastership if the current master falls out, it is preferable to
define communication interfaces as bus administrators, when it is possible.

3.2.1 Communications Interface CI520
3.2.1.1 Defining Communication Interface CI520
The CI520 communication interface is used in the Advant Controller 400 Series.
The DB element for the bus communication interface is shown in Figure 3-1.
3.2.1.2 Setting the CI520 Operational
When the CI520 is started and configured, it must be set operational in order to enable
communication on the Advant Fieldbus 100, and to participate in the sharing of the bus master
responsibilities. This is done automatically by the Advant Controller 400 Series.
If the CI520 is the first communication interface to become operational, it immediately assumes
the bus master responsibilities.
If another communication interface becomes bus master before the CI520, the CI520 will detect
the presence of a bus master on the Advant Fieldbus 100 and work to get synchronized.
If a CI520 is commanded operational on a bus where other communication interfaces already
shares the bus master responsibilities, the CI520 sends a message to the current master to notify
its presence. The current bus master then sends the scan table to the CI520 while carrying out
the bus master responsibilities. The CI520 adds its own CDPs to the scan table and then asks to
become the current bus master. After receiving the bus mastership the new updated scan table is
distributed to all other bus administrators.
If a CI520 gets its configuration changed on-line due to changes in the database. The CI520
updates its own scan table and then a
