Kepware如何实现不同层级的冗余 在工业通信领域中，为了确保系统的正常运行，减少故障时间，提高可靠性，通常都需要对系统进行冗余设置。在冗余配置的过程中经常会遇到一些这样那样的问题，下面就一起来看看，Kepware如何实现不同层级的冗余吧!Kepware针对工业现场通讯实现冗余主要分两个层级:设备层冗余、服务器层冗余。 1. 设备层冗余 Kepware针对设备层提供Media Level Redundancy Plug-In来实现冗余，适用于使用串行或以太网进行通信的设备。用户可以在KEPServerEX的设备属性中设置冗余对，如下图所示，在主设备里设置“次级路径”来关联从设备，进而实现冗余设置。 设置完成后，上位只要访问主设备采集数据即可。当主设备出现问题后，会自动将备用设备数据给到上位，当主设备恢复通讯后会自动切换回主路径通讯。 2. 服务器层冗余 服务器层冗余，主要针对上位程序访问Kepware而言，根据通讯协议不同有不同的解决方案。 OPC DA： Kepware提供RedundancyMaster软件来实现OPC DA 的冗余，可在RedundancyMaster中设置“冗余对”，进行冷/温/热三种模式的冗余设置。 OPC UA： 针对OPC UA Server，KEPServerEX的OPC UA Client 驱动中支持冗余设置，设置方式同上述设备层冗余。 其他应用冗余--如ODBC Kepware支持通过Datalogger插件将数据写入例如SQL等关系型数据库，对于数据库存储想要保证数据高可靠性，又不想进行数据的重复存储可以使用如下方案 主备两个Kepware服务器配有相同的驱动，并都使用Datalogger来实现数据库的存储，期间备用服务器Kepware使用Ping驱动来主动获取主服务器的网络状态，当发现网络异常时，才触发存储动作进行数据写入数据库。 。
