Calculate the distance of item in the conveyor

Hi, everyone.

How to calculate the distance of every item travel in my MergeSort Conveyor.

I had planned to calculate the time of item stay in conveyor, and then get the distance by multipled the speed of conveyor. While the item would be blocked during its conveying, this approach can not get the right distance.

For example: In the attached model how can I calculate the distance of each item travel in the conveyor?

Did anyone have a good idea to solve it?

Since Version 17.2.5. there exists the property "totalDistance" for the class Conveyor.Item. If you place a photo eye right before the exit Transfer you can get the Totaldistance of every item leaving the conveyor system. In the Decision Point you assert a label to the item to distinguish which item leaves next. calculate-conveyor-item-distance.fsm

Yes! Thanks! That is exactly what I want.

And I found the command which can be used in below V17.2:

conveyorinfo(obj conveyor,CONV_INFO_ITEM_TRAVEL_POS,obj item); //the "conveyor" is where the item stay in.

@jing.chen

This may be too simple but isn't it just the X position of the flowitem? Doesn't that give you the distance that the flowitem has traveled on any particular conveyor?

Thanks for your answer.

But I not quite understand what your mean. I attached a demo model which the item will come from different entries and it may not leave the conveyor when it meets the exitTransfer.
