本章的配置部分与Advant OCS with Master相关
软总线上使用的快CDP周期时间,用于检测伙伴不再存在。如果
伙伴是当前的主节点,在冗余对中执行切换。交换机
超过需要额外的时间,对于快速CDP,多需要几个周期,接收CDP将超时
切换时设置为无效。
对于切换处理,如果CDP在切换时暂时无效,
冗余CI522的CDP超时设置为双倍,即八个周期,而不是四个周期。
注释
用于1、2和4毫秒CDP的双超时为40毫秒。
在以下情况下需要双重超时:
•由于切换,具有相应DSP的CDP必须无效=0。
•使用S800 I/O。由于切换,S800 I/O模块不得进入OSP状态。
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。fastest CDP cycle time used on the bus, to detect that the partner is no longer present. In case the
partner is the current primary, within the redundant pair, a switch over is performed. The switch
over needs extra time, up to several cycles for fast CDPs, and receiving CDPs would time out
and be set non valid in case of a switch over.
For switch over handling, without CDPs momentarily being non valid at the switch over,
the CDP time out for redundant CI522s is set double that is eight cycles instead of four.
NOTE
Double time out, used for 1, 2 and 4 ms CDPs, is 40 ms.
Double time out is needed when:
• CDPs with corresponding DSPs which must not get valid = 0, due to a switch over.
• S800 I/O is used. The S800 I/O Modules must not enter OSP state, due to a switch over.
The 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
