你好
Hi,
在PLC中使用Y_LINK的实际目的是什么?
What is the actual purpose of using Y_LINK In PLC?
你好,chet;
Hello chet;
以下常见问题解答中对使用Y-Link作为冗余H系统CPU和标准Profibus从站之间的网关进行了很好的解释:
There is a very good explanation of the use opf a Y-Link as a gateway between redundant H-system CPUs andstandard Profibus slaves in the following FAQ:
-
描述
Description
Y链路用于将只有一个DP接口的远程IO设备连接到冗余H系统。
The Y Link is used to connect remote IO devices that have only one DP interface to a redundant H system.
Y链路由两个IM 153-2接口模块和一个Y耦合器组成。
The Y link consists of two IM 153-2 interface modules and a Y coupler.
Y链路通过接口模块连接到冗余DP主系统。远程IO设备通过Y耦合器连接到Y链路,即:
The Y link is connected to the redundant DP master system via the interface modules. The remote IO devices are connected to the Y link via the Y coupler, i.e.:
Y链路创建一个从冗余DP主系统到单边DP主系统的网关。
The Y link creates a gateway from a redundant DP master system to a unilateral DP master system.

用简单的语言进行非常详细和良好的解释。
Very detailed and good explation in simple words. .
亲爱的朋友:,
Dear Friend,
根据我的想法,Y链接是一种设备,用于在冗余Profibus主站与标准Profibus从站之间进行通信。
As per My idea Y link is a Device to make the communication between redundant Profibus Master to Standard Profibus Slave.
这通常用于将驱动器(vfd或DC驱动器)与H系统通信。
Mostly this is used to communicate Drive(vfd or DC Drives ) to H-system.
当做

还应注意,操作员面板(按钮面板除外)通过Y链接与H控制器的连接是not 已发布。
It should also be noted that the connection of operator panels - except Push Button Panels - to an H controller via a Y link is not released.

您也可以使用两个profibus repeter代替Y-LINK。
You can use two profibus repeters also instead of Y-LINK.
在这种情况下,您必须打开和关闭专用中继器,以连接到冗余主设备的单profibus连接的从设备。
In this case you have to switch on & off the perticular repeater for conenctions to slaves with single profibus connection from the redundant masters.
您必须使用PLC DO作为中继器电源。你可以根据哪个CPU成为主CPU来进行开关操作。
You have to use PLC DO for repeater supply.That DO you can make on & off as per which CPU is becoming Master.
你好
Hello,
对于HMI通信,这是可以的。
For HMI Communication it is ok.
但如果我能用它和RIO交流呢?
But what if i could use it to communicate with RIO?
我确信它不会提供无冲击转换。
I am sure that it will not give bumpless changeover.
我同意Amit_86
I'm agree with Amit_86
切换时间可能需要2秒钟。两秒钟的监控时间并不长,但对控制系统来说时间太长。
Changeover time may take up to 2 seconds. Two seconds isn't a long time for monitoring, but too much time for control system.
你好
Hello,
你好,艾曼,
Hello Ayman,
这是我在一个项目中的个人经历。
This is my personal experience in one of the my projects.
有些自动化应用程序速度很快,有些则很慢。在这种情况下,我同意你的看法。
Some automation application are fast and some of them are slow. I'm agree with you in this case.
但此时,它可能会丢失一些瞬时信号。
But at this time, it may be lose some of the momentary signals.

因此,“两秒钟”不是静态持续时间。
So the "Two seconds" is not a static duration.
感谢您的澄清。
Thank you for clarification.
关于失去一些动量信号,真正的过程自动化不是一个问题。别担心。
And about loosing some momentry signals, really in process automation is is not an issue. Do not worry about it.
但在机器自动化中,您可能会因为切换时间而更改完整的解决方案。
But in Machine automation, you may change the complete solution because of this switchover time.
请注意,在过程自动化中,如果您选择S7-400H,并且您有SINAMICS驱动器通过profibus连接到系统,那么您必须使用Y-Link。没有其他解决方案。
And please note that in Process autolation, if you should go for S7-400H and you have SINAMICS drive connected to the system via profibus, then you have to use Y-Link. There is no other solution.
对不起,艾曼。我不同意这一点。
Sorry Ayman. I am not agree for this.
它也依赖于过程自动化的应用。。。
