Stop at conveyor station

The attached model has a station on the conveyor and is controlled so that flow items from the back will not come while it is being processed at the station.

I would like to change this to a model that flows while stopping two flow items at the station as shown in the attached image.

As much as possible, I would like to operate without using the process flow.

@tomonori S,

You don't get much control over things like this unless you use Process Flow. But, you can still create primitive solutions without too much complex custom code.

One example of a solution is adding a photo eye at the beginning of the series of stations that assigns a label of "Process" to each item. Every other item receives a Process value of 1, which the Stations then use to determine whether or not the item should be processed.

This works just fine, but if you want more control, you're going to need Process Flow.

I checked the model.As you can see in the attached image, when the simulation is executed for about 180 seconds, items flow from behind.

It seems that the control to prevent it from flowing from the rear is not working during processing at the station.

A model is also attached, so please check.

@tomonori.s,

Try the model with the Acquire/Release Area Restrictions active in the triggers.
