## Fields
| 参数名 | 类型 | Unit [Frame] | Range/Enum | 描述 |
| ------------------------------------------------------------------------------------------- | ---------- | ---------------------------------------------------------------- | ---------- | -------------------------------------------------------------------------------------------------------------------------- |
| timestamp | `uint64` | | | time since system start (microseconds) |
| request_id | `uint64` | | | ID, set this to a random value |
| name | `char[25]` | | | either the requested mode name, or component name |
| px4_ros2_api_version | `uint16` | | | Set to LATEST_PX4_ROS2_API_VERSION |
| register_arming_check | `bool` | | | |
| register_mode | `bool` | | | registering a mode also requires arming_check to be set |
| register_mode_executor | `bool` | | | registering an executor also requires a mode to be registered (which is the owned mode by the executor) |
| enable_replace_internal_mode | `bool` | | | set to true if an internal mode should be replaced |
| replace_internal_mode | `uint8` | | | vehicle_status::NAVIGATION_STATE_\* |
| activate_mode_immediately | `bool` | | | switch to the registered mode (can only be set in combination with an executor) |
| not_user_selectable | `bool` | | | mode cannot be selected by the user |
