AC 800F控制器冗余
控制器冗余可通過安裝兩個AC 800F。為確保在主AC 800F發(fā)生故障時，secon dary AC 800F能夠快速、順利地接管
通過第二個以太網(wǎng)的冗余通信鏈路模塊確保兩個AC 800F始終同步。所有輸入和輸出均設(shè)計為支持冗余活動
Profibus線路冗余使用冗余鏈路模塊RLM 01將一條簡單的非冗余Profibus線路轉(zhuǎn)換為兩條相互冗余的線路。
1MRB178066R1E控制主板您可以直接定位冗余鏈路模塊RLM 01在Profibus模塊（主）之后，在總線段之前幾個奴隸或在一個奴隸之前。帶有冗余耦合器的PROFIBUS站可以直接連接到PROFIBUS設(shè)置為RLM 01冗余。只有一個接口的樁號可以選擇分配給一條或另一條線路。
冗余鏈路模塊的技術(shù)說明日期RLM 01見文件3BDD011600R0201。
Profibus線路冗余的另一種解決方案是使用光纖環(huán)，例如OZD Profi 12M模塊來自Hirschmann公司
AC800F冗余與Profibus線路冗余你可以實現(xiàn)這兩個目標(biāo)；控制器冗余和Profibus線路通過使用兩個AC 800F和一個RLM01實現(xiàn)冗余。這拓?fù)浣Y(jié)合了控制器冗余的優(yōu)點具有上述線路冗余之一段落。
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.
