AC 800F控制器冗余
控制器冗余可通过安装两个AC 800F。为确保在主AC 800F发生故障时，secon dary AC 800F能够快速、顺利地接管
通过第二个以太网的冗余通信链路模块确保两个AC 800F始终同步。所有输入和输出均设计为支持冗余活动
Profibus线路冗余使用冗余链路模块RLM 01将一条简单的非冗余Profibus线路转换为两条相互冗余的线路。
1MRB178066R1E控制主板您可以直接定位冗余链路模块RLM 01在Profibus模块（主）之后，在总线段之前几个奴隶或在一个奴隶之前。带有冗余耦合器的PROFIBUS站可以直接连接到PROFIBUS设置为RLM 01冗余。只有一个接口的桩号可以选择分配给一条或另一条线路。
冗余链路模块的技术说明日期RLM 01见文件3BDD011600R0201。
Profibus线路冗余的另一种解决方案是使用光纤环，例如OZD Profi 12M模块来自Hirschmann公司
AC800F冗余与Profibus线路冗余你可以实现这两个目标；控制器冗余和Profibus线路通过使用两个AC 800F和一个RLM01实现冗余。这拓扑结合了控制器冗余的优点具有上述线路冗余之一段落。
AC 800F Controller Redundancy
Controller redundancy can be achieved by installing two
AC 800F. To ensure quick and smooth takeover by the secon
dary AC 800F in case the primary AC 800F fails, a dedicated
redundancy communications link through the second Ethernet
module makes sure that both AC 800F are always synchro
nized. All inputs and outputs are designed to support redundant
operation.
Profibus Line Redundancy
Using the Redundancy Link Module RLM 01 will do the conver
sion of one simple, non-redundant Profibus line into two recip
rocally redundant lines.
You can position the Redundancy Link Module RLM 01 directly
after a Profibus module (master), before a bus segment with
several slaves or before an individual slave. PROFIBUS sta
tions with redundant couplers can be directly connected to the
PROFIBUS set redundant by RLM 01. Stations with only one in
terface can be optionally assigned to the one or other line.
For technical description dates of the Redundancy Link Module
RLM 01 see document 3BDD011600R0201.
An alternative solution to the Profibus line redundancy is to use
a Fiber Optic Ring, for example with the OZD Profi 12M module
from firm Hirschmann
AC800F Redundancy together with Profibus Line Re
dundancy
You can achieve both; controller redundancy and Profibus line
redundancy by using two AC 800F with one RLM01 each. This
topology combines the advantages of controller redundancy
with the one of line redundancy as described in the above
paragraphs.
