电缆类型的长度（300米（1000英尺）或700米（2300英尺））。
由此，我们得到了以下限制：
A+B+C+D+E<=1400米（4500英尺）和
A、 对于RG11，C、E<=700米（2300英尺）；对于RG59，E<=300米（1000英尺）
D<=750米（2500英尺）。
注意！
该公式也适用于8500和15000米配置，参见

图2-21显示了“树形”配置的Advant Fieldbus 100。与的规则相同
计算电缆长度时，图2-20有效。的区别是这两个车站
计算中使用的距离大。
由此，我们得到了以下限制：

la:
2,000 -- 4 x 150 = 1,400 meter
or in ft
6,500 - 4 x 500 = 4,500 ft
The total physical cable length, optical cable + coaxial cable + twisted pair cable, in the figure
can be up to 1,400 meters (4,500 ft), according to the calculation above. This length can be split
up any way between the five different parts, as long as no coaxial cable exceeds the maximum
length for it’s type of cable (300 m (1,000 ft) or 700 m (2,300 ft)).
By this, we got the following restrictions:
A + B + C + D + E <= 1,400 meters (4,500 ft) and
A, C, E <= 700 meters (2,300 ft) for RG11 or 300 meters (1,000 ft) for RG59 and
D <= 750 meters (2,500 ft).
NOTE!
This formula is applicable also for 8,500 and 15,000 meter configurations, see
Chapter 1.8.2 Advant Fieldbus 100 length concept for information about
equipment supporting these lengths.
When using Advant Fieldbus 100 in “tree” configuration the bus length is the distance between
the two stations on the bus that is most far apart.This means that a number of length between
different combination of pairs of stations must be taken into consideration in order to decide
which two station that is most far apart. The same roles regarding calculating methods for bus
length as well possible length is valid both for star configuration as well as the common bus
configuration.
The Figure 2-21 shows an Advant Fieldbus 100 in a “tree” configuration. The same rules as for
Figure 2-20 is valid when calculating the cable length. The only difference is that the two stations
that is most far apart is to been used in the calculation.
By this, we got the following restrictions:
A + B + C + D + E <= 1,400 meters (4,500 ft) and
A + B + C + F + G + H <= 1,400 meters (4,500 ft) and
E + D + F + G + H <= 1,400 meters (4,500 ft) and
A, (C + F), E, H <= 700 meters (2,300 ft) for RG 11 or 300 meters (1,000 ft) for RG59 and
D, G <= 750 meters (2,500 ft).NOTE!This formula is applicable also for 8,500 and 15,000 meter configurations, see
Chapter 1.8.2 Advant Fieldbus 100 length concept for information about
equipment supporting these lengths.
