产品详细资料
当配置为冗余IP操作时，活动和备份以太网接口也应配置为通过多播主机组或本地子网广播地址使用EGD交换。这允许活动单元和备份单元从网络接收新数据。艾默生不建议使用单播操作，因为不建议使用备份单元，因为它不会消耗冗余IP地址处的任何单播交换。1.4.9冗余系统中的EGD Class 2命令远程主机在与冗余系统通信时应使用冗余IP地址。只有激活单元对EGD命令作出响应。备份单元不响应冗余IP地址。当活动以太网接口更改为备份时，任何通过冗余IP地址的进程中EGD命令都将被放弃。当配置为冗余IP操作时，只有活动单元在网络上发送EGD命令。如果备份单元试图启动任何EGD命令，则COMMREQ错误状态返回到其应用程序。当活动以太网接口更改为备份时，任何正在处理的EGD命令都将结束。不建议向直接IP地址发出EGD命令；活动单元和备份单元都将响应在直接IP地址处接收到的EGD命令。
When configured for Redundant IP operation, the active and backup Ethernet interfaces should also be configured to consume EGD exchanges via multicast host groups or the local subnet broadcast address. This permits both the active and backup units to receive the latest data from the network. Emerson does not recommend Unicast operation as the backup unit is not recommended as it will not consume any unicast exchanges at the Redundant IP address. 1.4.9 EGD Class 2 Commands in a Redundancy System Remote hosts should use the Redundant IP address when communicating to a redundant system. Only the active unit responds to EGD commands. The backup unit does not respond to the Redundant IP address. When the active Ethernet interface changes to the backup, any in-process EGD commands over the Redundant IP address are abandoned.When configured for Redundant IP operation, only the active unit sends EGD commands on the network. If the backup unit tries to initiate any EGD commands, a COMMREQ error status is returned to its application program. When the active Ethernet interfaces changes to backup, any EGD commands in process are ended. Issuing EGD commands to the direct IP address is not recommended; both the active and backup units will respond to EGD commands received at the direct IP address.
