### 10.24.1 Device Motion Control Macro Attributes

#### 10.24.1.1 Device Motion Execution Mode

Device Motion Execution Mode (300A,0451) identifies how the operator invokes and controls the motion.

Enumerated Values:

CONTINUOUS

  The device must be moved while the operator is activating one or more switches on the machine during the whole period of movement to prevent any uncontrolled movement.

TRIGGERED

  The device can be moved automatically to the desired position, triggered by a one-time command of the operator, without the need to constantly activate any switch.

AUTOMATIC

  The device movement can be initiated and performed automatically by the device to the desired position.

#### 10.24.1.2 Device Motion Observation Mode

Device Motion Observation Mode (300A,0452) describes the presence of the operator in the room, observing the motion.

Enumerated Values:

INROOM

  The movement of the device is only allowed when the operator is present in the treatment room.

REMOTE

  The device can be moved by a command of the operator not being present in the treatment room, that is, from a device outside the treatment room.
