PROFIBUS协议结构是根据ISO7498国际标准，以OSI作为参考模型的。PROFIBUS-DP定义了第1、2层和用户接口。第3到7层未加描述。用户接口规定了用户及系统以及不同设备可调用的应用功能，并详细说明了各种不同PROFIBUS-DP设备的设备行为。PROFIBUS-FMS定义了第1、2、7层，应用层包括现场总线信息规范（FMS）和低层接口（LLI）。FMS包括了应用协议并向用户提供了可广泛选用的强有力的通信服务；LLI协调不同的通信关系并提供不依赖设备的第2层访问接口。PROFIBUS-PA的数据传输采用扩展的PROFIBUS-DP协议。另外，PA还描述了现场设备行为的PA行规。根据IEC1157-2标准，PA的传输技术可确保其本质性，而且可通过总线给现场设备供电。使用连接器可在DP上扩展PA网络。
