添加 MpIO 配置
要在运行时修改硬件配置，需要添加 MpIO 配置。
它包含 mapp 链接，可在 mapp 环境中唯一标识 mapp 组件。mapp 链接建立了编程和配置之间的连接。"备份设备名称 "指定了一个数据存储设备，在导入过程中将原始配置的备份文件存储到该设备中。数据存储设备已在硬件配置中定义。
Adding the MpIO configuration
To modify the hardware configuration at runtime, the MpIO configuration is added.
It contains the mapp Link, which uniquely identifies the mapp component within the mapp environment. The mapp Link establishes the connection between programming and configuration. "Backup device name" specifies a data storage device to which backup files of the original configuration are stored during an import. The data storage device was defined earlier in the hardware configuration.
