how to control the items flow on conveyors

I want to know how to stop and resume the items on conveyor using DP and PhotoEye.

I want to go on continue the second white item after stopping above picture.

The second white item should stop before one blank space for the process finished item passing.

After the second item stopping, it should resume on message from the cleared photoeye.

But it did not resume to go continue.

Hi @david.seo,

In PET_StopGo Photo eye type >> On Clear trigger >> Send a message to the center object of the photo eye. Then use the below code in On message trigger of the DPType_PassIn2 to resume the item.

Object item = current.activeItem;
Conveyor.Item conveyorItem = conveyor.itemData[item];
Object involved = current.activeItem;
involved.up.as(Conveyor).itemData[item].resume();

Thanks.

@Raja Sekaran

Thank you for your replying.

But the model added you answer and it did not show any difference to me.

Did you test your answer in the model? If you had it, please upload it here.
