Producer Consumer loop

[Izzzzz]

Hello *E* I took a look at your VI, and could not understand why you had the enums wired to the obtain queue, enqueue element, or deque element. These VIs should store the data you want the consumer loop to manipulate. I made some changes to this VI and you can find it attached below.

Thank you very much for your reply!

Can you please resend me the VI example in 2011 version or lower please?

thanks for the reply and down converting the file. Can you please give me a little explaination on how to get the data from the top producer loop to the bottom loop? I dont fully understand this example. It reads the data in like i would like but i need to know were to place the formulas in the bottom consumer loop as it it transfered to the bottom loop. So as it is reading the file line by line first row. Will down the calculation as it comes off the queue then apend down thru thw rows

If you wire the output from the Dequeue Element node in the lower loop you will get the row of data that the upper loop posted. The queue is used to pass data from one loop to another. One or more loops can post (enqueue) data to the queue. Only one loop should remove (dequeue) data from the queue.

Thank you for the explaination.

Mark i got it working thanks again to all that help! One more question i'm able to read in all data from spreadsheet with -1 or using the iteration from the top while loop in the producer loop. At the bottom consumer is there a way to have all the data put on the enqueue then when it is dequeueing. It read row by row using some type of iteration ? Right now the top loop reads all the data and the bottom loop dequeue output element out displays the first row only . I would like it to shift down thru each row one at a time if possible?

Thanks never mind i figured it out.

In the producer loop I am able to read in the whole spread sheet at one time. Then the data is passed in to an index array  then the out put is enqueued. Then it is dequeued at the bottom. Is there a way to make all the data available to the consumer loop soon after it is read in from the producer loop? right now im only able to read it in row by row as it is enqueued by the index array. I would like all rows and columns be available at the same time as a block  instead of row 1 then row 2 then row 3 etc. The reason being is the data in the file will be time stamped and over written so it need to all be available at the same time. I think the problem may be that its read in as a 2 D array and going in the enqueue as a 1 D array therefore its dequeue as a 1 D array.
