    • A redundant host pair runtime arrangement is disclosed for a process control network environment. The environment includes a primary network through which process control information is transmitted. An active partner of a fail-over host pair operates on a first machine communicatively connected to the primary network, and the active partner hosts a set of executing application components. A standby partner of the fail-over host pair operates on a second machine communicatively connected to the primary network. The standby partner receives updates including engine synchronization data associated with the set of executing application components to facilitate taking over an active partner role in response to a fail-over event. The environment also includes a redundancy message channel, separate and distinct from the primary network. The redundancy message channel provides a communications path between the first machine and second machine facilitating passing the updates including engine synchronization data.
    • 公开了用于过程控制网络环境的冗余主机对运行时布置。 环境包括传输过程控制信息的主要网络。 故障转移主机对的主动伙伴在通信地连接到主网络的第一台机器上运行,并且主动伙伴承载一组执行的应用程序组件。 故障转移主机对的备用伙伴在通信连接到主网络的第二台机器上运行。 备用伙伴接收包括与该组执行应用程序组件相关联的引擎同步数据的更新,以便响应故障切换事件接管活动伙伴角色。 该环境还包括与主网络分离和分离的冗余消息通道。 冗余消息信道提供第一机器和第二机器之间的通信路径,便于传递包括发动机同步数据的更新。
