question

@Jhonatan David HV, Good Morning to you, too. You have chosen as a topic “combiner”, right?

If you look for the threads to this topic, you get this link and pages of answers. Have you read some of the threads and none of them doesn‘t answer your question?

The keyword you are looking for is “Change Component List“ and it is a picklist option of the Combiners‘ On Entry trigger. The default procedure depends on the label Type of the item entering the combiner first through its input port number one and a special formatted global table. Each column contains a recipe of items entering the combiner through its input port starting with number 2 as the first row, 3rd input port is 2nd row and so on.

I am a bit confused that your recipe depends on a special sequence of products as you said above component 1, then component 2 and then at last component 1 again. This feature isn’t part of a combiner, but that doesn’t matter, because as long as a recipe contains all ingredients in total, you can let them enter the combiner in your desired fashion. You control this in the objects that send the items into the combiner. And there isn’t any restriction that tells you, you are only allowed to let enter a single Type of a component through one single port. Let make me this a bit clearer. Your container item has got for example 3 items of Type 1. Then it doesn’t matter if your recipe is set to get 3 items of 3 ports or to get 3 items through one port. Which items you send through a port has nothing to do with their Type. Only their amount is important by the component list recipe table.

In your example you need in total 9 items. One item must enter through port 1. That is a default condition you can’t change that. Then you need 8 items. I assume the first item is Type mp1, then you have set in combiners’ component list to receive 8 items. The object that is connected with its outport to the input port number 2 of the combiner organizes that next an item of type mp1 leaves it, then 3 items of type mp2 and last 4 items of type mp1 again. As you see the order of items which enters a combiner isn’t a feature of the combiner at all. A combiner combines only a distinct number of items through input port numbers. On the other hand you can support this by declaring that at each input port number greater than input port number one has got only one type available, then the combiner allows only the number of items to be received which you describe in your recipe. But this hasn’t got any influence on the order of items entering a combiner depending on time, this is something you can only control in the objects that send or release items to a combiner.
