EN 50170规定母线为A型线路。应避免使用B型线路。
介质的物理性质如表3-3和表3-4所示。
指定的线路参数会导致母线段的以下长度。
短截线敢达1500 kbit/s<6.6 m。
如果使用12 Mbit/s,则应避免使用短截线。
如果使用EN 50 170规定的线路A,则总线端接电阻组合
如图3-23所示,从而确保线路上具有规定的空闲状态电位。

为了桥接更长的距离并绕过EMC干扰,使用光纤传输
还规定了导体(玻璃或塑料)。
标准总线插头连接器可用于光纤导线传输。
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,中继器可用于处理该信号转换。
这使您可以在中的两种传输技术之间进行切换
如果需要,一个系统。
您可以将多达126个站点连接到一个Profibus系统。
为了能够处理总线上的参与者数量,总线系统必须被划分
每个段多包含32个站点。
这些段由中继器连接。

bus line is specified in EN 50170 as line type A. Line type B should be avoided.
The physical properties of the media are shown in Table 3-3 and Table 3-4.
The specified line parameters result in the following lengths of a bus segment.
Stub lines up to 1500 kbit/s < 6.6 m.
If you are using 12 Mbits/s you should avoid stub lines.
If you are using line A as specified by EN 50 170, the bus terminating resistance combination
is as shown in Figure 3-23, so that a defined idle state potential is ensured on the line.

Section 3.13.4 Commands through Profibus
3BSE029382R0101 Rev C 3-41
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.
These segments are linked by repeaters.

The scaling of analog outputs does not affect the measurement values transferred through
Profibus.
If zero set has been performed, the zero set values are transferred through Profibus.
Scaling of Profibus measurement values, see Section 3.13.5.2.
Each measurement value has 16 bit, 2-complement representation (Integer 16).

The Profibus values can be scaled in two ways:
• Default Scaling – scaling that only depends on load cell nominal load.
• User defined Scaling – the scaling of the Profibus values can be set by the user.
