Return Value
The number of workpiece data that meets the specified conditions is returned by integer type data.
Description
This command returns the number of workpiece data within the tracking buffer. The counting condition is determined by the user data and the count object.
If the number of data in the tracking buffer is zero, "0" is returned.
If the number of data in the tracking buffer is one or more, return values will be as follows.
| User data | Count object | Reurn value |
|---|---|---|
| Y | N | Return the number of data in the tracking buffer that belongs to the specified user data. |
| Y | Y | Return the number of count object specified that belongs to the specified user data. |
| N | N | Return the number of data within the tracking buffer. |
| N | Y | Return the number of the specified count object regardless of the user data. |

Attention
- This is the conveyor tracking operation-dedicated command.
- If the "Tracking Buffer Data" in the fourth argument of TrackTargetPos is "Enabled", the original data of the tracking-target work remains the tracking buffer. Note that the remained data in this tracking buffer is not the object of TrackCount command.
