中文摘要本发明涉及一种高可用性功能块冗余方法,包括以下步骤:对现场设备进行增设处理;组态并设置冗余关系,将上述增设处理后的现场设备组成现场回路,组态并设置相应的主功能块及备分功能块;对主功能块和备份功能块进行实时数据同步;当同一冗余关系中的主功能块失效时,最先发现的现场设备调用冗余切换请求服务发送冗余切换报文;备份功能块所在的设备即冗余设备接收并处理冗余切换请求报文,调用冗余切换命令服务,发布全局的冗余切换命令报文,通知所有相关设备进行冗余切换。本发明方法保证了控制过程的连续性,最大限度地保证了冗余链路和主链路之间数据的一致性,开发成本低;冗余切换速度快,具有广阔的应用范围。

英文摘要The invention relates to a high-availability function block redundancy method, which comprises the following steps that: field devices are subjected to addition processing; redundancy relationships are configured and set to enable the field devices after the addition processing to form a field circuit, and corresponding main function blocks and back-up function blocks are configured and set; real-time data synchronization are carried out on the main function blocks and back-up function blocks; when the main function blocks in the same redundancy relationship fail, the field devices which find the failure firstly call a redundancy handover request service to send a redundancy handover message; and the device in which the back-up function blocks are positioned (namely redundancy units) receive and process the redundancy handover request message, and call a redundancy handover command service to issue a global redundancy handover command message for notifying all related devices to carry out redundancy handover. The method ensures the continuity of the control process, and maximally ensures the consistency of the redundant links and the main links, and has the advantages of low development cost, quick redundancy handover speed and wide application range.[
