Pulling flowitem from racks

How to pull flow items from racks to queue using global table. Flow items are provided with labels such rack number, bay number, level number based on which required flow item has to pulled to queue. Have gone through many threads regarding pull option but in vain.
1. How to give reference in pull requirement for all the above mentioned labels using code?
2. whether need to specify any dwell time in racks before pull option?

Hello Manoj,

the uploaded PullSpecificItemfromRackCell_JV.fsm-model could give you a hint how to proceed. The main programcode is in the Pull Requirement in the queue.

The way is to find an logical expression, which compares a specific attribute with all to be released items in the rack. In my code I compare the pointer as a number of a flowitem in a specific cell to all the pointer numbers of items in the rack.

You don't have to specify a dwell time.

Hi Jörg,
The model is not opening. Its showing some error in system console showing "Error: GL_ARB_occlusion_query extension not available".

The model is opening and running without errors.

Maybe you have a local problem with your installation?!

I have attached the error message with this post. please check and guide.

Hello Manoj,

which version of Flexsim do you use?

Jörg

Flexsim 5.0

Hello Manoj,

the following code should be in the Pull Requirement of the object which pulls from the rack. I have used a queue.

treenode current = ownerobject(c);
treenode item = parnode(1);
int port =  parval(2);
/**Specific item of a rack cell*/
treenode racktable = getvarnode(inobject(current,1),"contenttable"); // Node of the table of all stored items
treenode rackcell = gettablecell(racktable,3,1); //node to the Rack cell 3rd bay, 1st level 
treenode cellcontent = first(rackcell);// node of the stored item. The node value is a number and reference to the item
double cellitem = getnodenum(cellcontent);// get the number
return cellitem == tonum(item); // if the number of the item to be released is equal to the stored value, receive that item.

The Rack has a size of 3 bays and 2 levels. The Place in Bay and Place in Level Functions are set to first available with a cell capacity of 1. The maxcontent of the Rack is 6.
