.. _struct_CONVEYOR_TRACK:

CONVEYOR_TRACK
===============

This structure represents a **conveyor tracking status**,  
defining whether tracking is active, the synchronization state,  
and the tracking duration information.

.. note::
   - ``MONITOR_CONVEYOR`` → checks conveyor on/off state.  
   - ``CONVEYOR_OBJECT`` → defines an object carried on the conveyor.  
   - ``CONVEYOR_TRACK`` → tracks synchronization and runtime status.  
   - These structures work together for conveyor-based material handling and vision tracking.
