Basic PROFIBUS PA design versions when
使用PA链接作为PA路由器
此时显示基本PROFIBUS PA设计版本。
PA链接用作这些配置中的PA路由器
例子。
但是,PA路由器只能通过DP / PA实现
耦合器。profibus dp连接直接在
耦合器而不是每个接口模块。
PROFIBUS PA设备的数量根据
specifications in section "Technical data".
Line architecture with single coupler
最大限度。5个PROFIBUS PA线(线段)可以运行
通过单耦合器(最大3.用环的混合配置或
耦合器冗余)在PA链接作为PA路由器,配备了
to 5 DP/PA couplers.
In the line architecture with individual couplers, each line
segment is connected to one DP/PA coupler of the PA router.
帕router can be connected to a single or redundant
PROFIBUS DP..
The FDC 157-0 the first choice as the DP/PA coupler. When
using this coupler, the PA devices can be integrated into the line
通过Active Field Distributor AFD4和AFD8进行段(批准
对于EX SEAT 2/22)和AFDIS(exz区1/21批准)。帕
设备通过短路连接到这些现场分配器。

最多8型现场分销商AFD4 / AFD8,5个现场分销商
of type AFDiS, or 5 field distributors of both AFDiS and AFD4/
组合的AFD8类型可以在线中可选地操作

根据危险区域的本质安全PA设备

EX区域1/21中的设备,通过线段连接
the PA router with DP/PA coupler Ex [i] is a possible alternative.
The devices are integrated separately into the line segment via
SplitConnect水龙头(通过Spur Line或通过SplitConnect M12直接

By grouping individual devices in different line segments,
设备级别可以灵活的模块化冗余。
Line architecture with redundant coupler
帕link operable as a PA router on a single or redundant
PROFIBUS DP.can only be equipped with one redundant DP/PA
耦合器对(最多3个单耦合器也可选地

对于具有活动场分路器(AFS)的线架构或环形架构

通过线架构,AFS连接到冗余

誓库4., AFD8 or AFDiS. The limits with respect to the number of
现场分销商也是相同的(最多8 AFD4 / AFD8,最多
5 AFDIS或最多5个AFDIS和AFD4 / AFD8的任何组合)。
