ABB 5SHY3545L0014数字量输入卡件

产品详细资料
SVC_REQ 55对未配置为冗余IP操作的以太网接口没有影响。1.4.4冗余系统中的SRTP服务器操作只有活动单元在冗余IP地址处维护SRTP服务器连接，并且可以响应SRTP请求。备份单元不响应冗余IP地址。当以太网接口从活动状态变为备份状态时，它会断开所有SRTP服务器连接及其使用冗余IP地址的底层TCP连接。活动单元和备份单元都在直接IP地址处维护SRTP服务器连接，以便与编程器进行网络通信。其他远程主机在与冗余系统通信时应使用冗余IP地址。当以太网接口在活动状态和备份状态之间切换时，直接IP地址处的现有SRTP服务器连接不会受到干扰。冗余系统中的SRTP客户端操作只有活动单元建立和维护SRTP客户端连接（通道）。备份单元不会启动任何SRTP客户端操作。如果尝试SRTP客户端操作，则会向本地逻辑程序返回COMMREQ错误状态。当以太网接口从活动状态变为备份状态时，它会断开所有SRTP客户端连接及其底层TCP连接。
SVC_REQ 55 has no effect on Ethernet interfaces that are not configured for redundant IP operation. 1.4.4 SRTP Server Operation in a Redundancy System Only the active unit maintains SRTP Server connections at the Redundant IP address and can respond to SRTP requests. The backup unit does not respond to the Redundant IP address. When an Ethernet interface changes from active to backup state, it takes down all SRTP Server connections and their underlying TCP connections that use the Redundant IP address. Both the active and backup units maintain SRTP Server connections at the direct IP address for network communication with the programmer. Other remote hosts should use the Redundant IP address when communicating to a redundant system. Existing SRTP Server connections at the direct IP address are not disturbed when the Ethernet interface switches between active and backup states.SRTP Client Operation in a Redundancy System Only the active unit establishes and maintains SRTP Client connections (channels). The backup unit does not initiate any SRTP Client operations. If SRTP Client operations are attempted, a COMMREQ error status is returned to the local logic program. When the Ethernet interface changes from active to backup state, it takes down all SRTP Client connections and their underlying TCP connections.
