既然PROFIBUS-DP是一种通讯标准，一些符合PROFIBUS-DP规约的第三方设备也可以加入到PROFIBUS网上作为主站和从站，绝大部分设备都可作为从站，只有一小部分设备可作为主站，第三方设备做主站，组态软件需要第三方提供。第三方设备作从站，如果主站是S7设备，组态软件是STEP7和SIMATIC NET，如果是S5设备，组态软件是COM PROFIBUS或COM5431。支持PROFIBUS-DP的从站设备都会有GSD文件，GSD文件是对设备一般的描述，通常以GSD或GSE文件名出现，将此GSD文件加入到主站组态软件中后就可以组态从站的通讯接口。在这里主要介绍S7设备做主站的应用，STEP7作为组态软件加入PROFIBUS-DP从站设备，现以S7-400 CPU416-2DP做主站，S7-200 PROFIBUS接口模块EM277作从站为例，详细介绍怎样导入GSD文件，组态从站通讯接口区进而建立通讯。
