photo eye issue

Using Photo Eye, I'm trying to send a message if an item doesn't come in for 10 seconds.


But I get an error.

time: 93.144454 exception: FlexScript exception: Invalid item in Conveyor.itemData[] call at MODEL:/PE1>variables/localType/clearTrigger
What is the cause of this error?

How should I handle the error?

If you've a long delay on the clear trigger then it's likely the item has left the conveyor system. Get around it by commenting out this line:

  1. Conveyor.Item conveyorItem = conveyor.itemData[item];
