也称为GSD文件（参见附录A.7 Profibus DP-PFEA112的GSD文件）。然后将该文件存储在Profibus Master中。在启动时，Profibus Master验证总线上是否确实存在具有给定类型文件的从设备。为了桥接更长的距离并绕过EMC干扰，还指定了光纤导体（玻璃或塑料）传输。标准总线插头连接器可用于光纤导体传输。这些连接器将RS 485信号转换为光纤导体信号，反之亦然。（OLP=光链路插头）。此外，中继器可用于处理这种信号转换。这使您可以在必要时在一个系统内的两种传输技术之间进行切换。最多可将126个工作站连接到一个Profibus系统。为了能够处理这一数量的公交参与者，公交系统必须划分为单独的部分，每个部分最多包含32个车站。also known as GSD file (See Appendix A.7 Profibus DP - GSD File for PFEA112). This file is then stored in the Profibus Master. At start-up the Profibus Master verifies that the Slave with the given type file is indeed available on the bus.To bridge longer distances and bypass EMC interference, transmission with optical fiber conductors (glass or plastic) is also specified. Standard bus plug connectors are available for transmission with optical fiber conductors. These connectors convert RS 485 signals to optical fiber conductor signals and vice versa. (OLP = optical link plug). In addition, repeaters are available to handle this signal conversion. This gives you the option of switching between the two transmission techniques within one system if necessary. You can connect up to 126 stations to one Profibus system. To be able to handle this number of participants on the bus, the bus system must be divided into individual segments, containing maximum 32 stations each.
