GSD文件
GSD文件用于识别Profibus DP设备。（大师或
从）。它包含的数据使依赖于制造商的配置工具成为可能。
GSD文件中的典型信息是供应商信息，
支持的波特率、定时信息、选项/功能
支持和可用的I/O信号。GSD文件必须可用
对于每个DP从机。DeltaV系统使用以下信息：

冗余主设备的切换时间小于100ms，随后检查输出信号并重新扫描总线，以确保：
该过程将不受干扰。
备份卡监控活动主卡的运行状况，而控制器监控冗余对的运行状况。当
如果检测到故障，系统将自动切换到备用主机。主服务器完整性错误的硬件警报
该卡可用于通知操作员或维护技术人员切换事件。还监控备份卡的以下内容：
完整性标志。
可能导致切换的事件包括。
„活动卡内的硬件故障。
„活动卡和控制器之间的通信故障。
„从载体上卸下活动卡。
„检测现场接线中的故障
也可以从诊断资源管理器手动启动切换。两张卡及其通道的运行状况和状态
也可在诊断资源管理器中找到。
系统自动委托新的备用卡。在安全区域，故障卡可以在电源下更换。危险的
区域，必须遵循适当的安装程序。
备用卡固定在地址0，并定期在段上声明自己为2类主卡，以验证连接。另外
当未设置为更高值时，2类主控卡可能与备用卡冲突，冗余Profibus卡不支持
地址大于1。

GSD Files
A GSD file is used to identify a Profibus DP device. (master or
slave). It contains data making it possible to have manufacturerindependent configuration tools.
Typical information in a GSD file is vendor information,
Baud rates supported, timing information, options/features
supported and available I/O signals. A GSD file must be available
for every DP slave. The DeltaV system uses the information in
the GSD file to set up the communications to the slave device.
The GSD can be imported into the DeltaV system to add the
new slave to the library.
Redundant Operation
The active and standby masters are connected to the segment
at the redundant terminal block, supporting a simplex wiring
scheme. Configuration of redundancy is not required as the
DeltaV system automatically recognizes the redundant pair of
cards and assigns device signal tags (DST) to the channels on
the primary card.

Switchover time for redundant master is less than 100 ms, followed by an output signal check and rescan of the bus to ensure that
the process will be undisturbed.
The backup card monitors the health of the active master, while the controller monitors the health of the redundant pair. When a
fault is detected, the system automatically switches to the backup master. A hardware alert on the integrity error for the primary
card can be used to notify the operator or maintenance technician of a switchover event. The backup card is also monitored for
integrity flags.
Events that can cause a switchover include.
„ Hardware failure within the active card.
„ Communications failure between the active card and the controller.
„ Removal of the active card from the carrier.
„ Detection of a fault in the field wiring
A switchover may also be manually initiated from the diagnostics explorer. The health and status of both cards and their channels
are also available in the diagnostics explorer.
The system automatically commissions a new standby card. In safe areas, failed cards can be replaced under power. In hazardous
areas, appropriate installation procedures must be followed.
The Standby card is fixed at address 0 and periodically declares itself on the segment as a Class 2 master to verify connectivity. Other
Class 2 masters may conflict with the standby card and are not supported with the redundant Profibus card when not set to a higher
address than 1.
