Select input for a combiner

Hi,

I have 2 combiner problems:

The 1st case is : there are 3 input for a combiner: A,B & C

I would like to combine A or B with C in random , but not both, how to set conditional input?

----------------------------------------
the 2nd case is: there is 2 input for a combiner: D & E and connected to input port 1 & 2 respectively
If I want to combine 2 items from D and 1 items from E, and remain D connected to port 1, it seems that I cant achieve the above requirement as in the component list of the combiner is base on a single item from port 1.

Regards,

Kelvin

Kelvin,

I searched for "combiner component list" in the forum and he found this thread:

I am pretty sure, that this thread is helpful for you.

I guess all you need to do is to update the component list of the combiner and you use randomness to do so.

Have a look into the thread and I hope you will find a solution.

Good success!

In your second case you could make two connections from D so that it is connected to port 1 and port 2 or 3. With E connected to port 2 or 3 as well by default you would combne 2 of D and 1 of E. In other words, you're allowed to connect the same object to the Combiner (or any object), more than once which can be helpful in cases such as this...

Hi Tom,

I read the case u mentioned above. This works if there is a main conponent and it must enter the combiner. If the case in "pick to light system" changed to there is 2 sources of pallet but not one, the pallet picklist can't control which pallet source to be used.

Kelvin,

Combiners only combine into port 1 and can not be easily changed to opperate differently. So,if you have two different sources that can be used then you'll have to set the model up to have the two pallet sources go to a queue that picks the right pallet and then have the queue connect to the first port of the combiner. This will allow you to have two different types of pallets. You can close the input of the queue on entry and open the input of the queue on exit of the combiner so that they act like a single object.

Good Luck,
Brandon

You could also try setting your Combiner to "Pull" and use a Pull Requirement to pull in the desired item from port 1. Just be aware that the pull requirement will be executed for all input ports, so you'll probably want to write if(port==1) .... else return true;

Hi Brandon,

Thanks for your idea, and actually this is the solution now i'm using. A dummy queue is added before the combiner for the selecting source function.
