GSD文件含义

大家好，欢迎来到IT知识分享网。

GSD即电子设备数据库文件，用于Profibus-Dp主站与从站交换数据时的参考数据，当主站与从站使用简介组态时，可以利用组态工具存取当前的参数和有关DP从站的GSD数据（电子设备数据库文件）？。

GSD 文件的组成：

1. 一般规范 这部分包括生产厂商和设备的名称，硬件和软件的版本状况，支持的波特率一可能的监视时间问隔
2. 与DP 主站有关的规范这部分包括只运用于DP 主站的各项参数(如连接从站的最多台数或上装和下装能力)。这一部分对从站没有规定；
3. 与DP 从站有关的规范 这部分包括与从站有关的一切规范(如输入／输出通道的数量和类型、中断测试的规范以及输入／输出数据一致性的信息)。

GSD文件规范： 
在GSD文件中，“；”作为注释符。#Profibus_D作为文件正式开头。

； 
Redundancy：（默认） ——设备是否支持冗余传输机制。 
Repeater_Ctrl_Sig：（默认）——Here, the level of the bus connector signal CNTR-P is specified——0: Not connected, 1:RS485, 2:TTL

Implementation_Type——描述了DP从站使用了哪些标准实现。比如，软件标准，控制器或是ASIC方案。此描述由标准方案提供商给出，GSD规范里也要遵从它。(例：“SPC3”) 
Bitmap_Device——用于一般情况下，代表设备特征的位图文件的文件名。格式为.DIB，70*40像素(宽高) 
Bitmap_SF——用于特殊运行情况下，代表设备特征的位图文件的文件名。格式为.DIB，70*40像素(宽高)

User_Prm_Data_Len——Length of User_Param_Data 
;— Module-Definitions — 
Module——I/O配置数据，与初始化报文中的CFG一致 
EndModule
