Set Combiner Pack quantity by Globalvariabel?

Is it possible to set the Combiner Pack quantity by Globalvariabel?

Put this code in the OnMessage trigger

setnodenum(node(">variables/componentlist/From Input Port 2/Target Quantity", current), GlobalVariable);

and set the OnReset trigger to

senddelayedmessage(current,0,current);

Depending on what you want to do in your model, I would think about using a GlobalTable - and get the table value - instead of a GlobalVariable.

// Edit:

Or if you have multiple input ports to your combiner and you don't care how many FlowItems per ItemType are collected you could just use:

setvarnum(current,"targetcomponentsum",GlobalVariable);

I have a batch productionsystem and i wont only pre-set my 9 combiners by GV. I wont that i dont need to change it in every combiner when i change the batch size in my system.

Why i should send a message to the combiner itselfe on reset, i thing it should by sufficiently to take the change on reset?

Hi Peppino,

well, then the solution to use a GlobalVariable might be sufficient. It's just a personal experience that I always create a GlobalTable called paramters for my simulation model where I control all variables that I might have to change quickly.

About the reset trigger:
Especially with creating FlowItems it's better to create them with the OnMessage trigger combined with a message instead of creating directly in the OnReset trigger.

From Anthony Johnson:

It's generally a bad idea to create flowitems on reset. The point of reset is to set the model to an initial state, and not to begin logic for the next model run. Instead, the reset trigger should send a delayed message in 0 time, and then perform the logic in the message trigger. This is so that the model will do its initial population when the user hits the run button, and not the reset button.

So you are right. In your case it should be totally ok to use the OnReset trigger

Better test it first. What if the reset of the object is executed after your code and on reset the Target Quantity nodes are reset to 0?

So I would always use a delaymessage to prevent you interfering with the standard code of the object!

Hi Jens,

I think that is a good idea, i will use it next time.

About the reset trigger:
That sounds logic, i´ve done it by a delaymessage.

But now i have an other problem. I have all ready a rack in my model that creat on reset his opening balance, but it´s working fine i can´t find any errors.
I´ve done it in that way because i realse items on message.

I think i can change i by an "if" where i check a massage with value maybe 99. When true creat items, else releas item.

Or somebody, know some better?

I tried it, it works!
