1756-L7RMEN    |  以太网冗余接口   |   保数据的实时性和准确性

目录号:1756-L7RMEN

以太网冗余

外壳类型等级：无（开放式）

以太网端口：1 根以太网光纤

CIP 未连接的消息： 128 + 128 （背板 + 以太网）

当前消耗 ：1.2 A @ 5.1V 直流，3 mA @ 24V 直流

以太网电缆：多模光纤，LC连接器

接线类别：3 - 在 USB 端口上

1756-L7RMEN以太网冗余是网络通信中的一种重要机制，用于提高系统的可靠性和稳定性，确保数据的实时性和准确性。在以太网冗余中，成员接口有两种状态：激活状态和非激活状态。1756-L7RMEN在任意时刻，同一个以太网冗余接口内只有一个成员接口处于激活状态，能够收发报文，而另一个接口则处于非激活状态，不能收发报文。当激活接口的链路出现故障时，处于非激活状态的接口会自动激活，接替原激活接口收发报文，实现接口间的备份。

1756-L7RMEN Ethernet redundancy is an important mechanism in network communication, which is used to improve the reliability and stability of the system and ensure the real-time and accuracy of data. In Ethernet redundancy, member interfaces have two states: active and inactive. 1756-L7RMEN At any time, only one member interface of a redundant Ethernet interface is active and can send or receive packets, while the other member interface is inactive and cannot send or receive packets. When the link of the active interface is faulty, the inactive interface is automatically activated to send and receive packets over the original active interface. In this way, inter-interface backup is implemented.
