产品详细资料
多个SNTP服务器(仅适用于SNTP广播和多播模式)为了防止SNTP定时消息丢失,可以在网络上跟踪多个SNTP时间服务器。以太网接口一次多可以维护四个SNTP时间服务器的定时信息。每个服务器分配一个层次号,该层次号决定其优先级。以太网接口使用来自具有低层号的服务器的消息,直到与该服务器的通信丢失。然后,具有下一个低层号的服务器成为所选择的服务器,并且如果以太网接口在150秒的时间段内接收到两个定时消息,则以太网接口与之同步。如果定时消息之间的间隔超过150秒,则服务器被视为“丢失”。SNTP定时信号的丢失或缺失如果为SNTP配置了以太网接口,但在150秒内没有从SNTP网络时间服务器接收到两条后续定时消息,则会发生以下情况:▪ 故障条目将被放置在PLC故障表中。▪ 一个故障条目将被放置在以太网接口的异常日志中。可以使用Station Manager读取此日志。
Multiple SNTP Servers (Applies only to SNTP Broadcast and Multicast Mode) To guard against loss of SNTP timing messages, multiple SNTP timeservers can be tracked on a network. An Ethernet interface can maintain timing information from up to four total SNTP timeservers at a time. Each server assigns a stratum number that determines its priority. The Ethernet interface uses the message from the server with the lowest stratum number until communication with that server is lost. Then the server with the next lowest stratum number becomes the server of choice and the Ethernet interface synchronizes to it if it receives two of its timing messages within a 150-second period. A server is considered "lost" if more than 150 seconds elapse between timing messages.Loss or Absence of SNTP Timing Signals If an Ethernet interface is configured for SNTP, but does not receive two subsequent timing messages from an SNTP network timeserver within a 150-second period, the following will happen: ▪ A fault entry will be placed in the PLC Fault Table. ▪ A fault entry will be placed in the Ethernet interface's exception log. This log can be read using the Station Manager.
